On 14 September 2026, attackers compromised Brevo’s infrastructure, injecting malicious code into JavaScript assets that reached over 100,000 customer websites. WordPress administrators had backdoor plugins silently installed while logged in; regular visitors faced ClickFix credential-harvesting overlays. Meanwhile, the Clop threat group continues exploiting CVE-2026-12569 in PTC Windchill with a custom web shell built for rapid data exfiltration, targeting UK manufacturing and engineering supply chains. A third campaign involves Settra ransomware maintaining persistence via MeshAgent, a legitimate remote monitoring tool that endpoint security often trusts by default. All three attacks share one structural weakness: reliance on third-party platforms, scripts, and tools that UK small businesses cannot directly audit or control. This briefing walks through the mechanics of each campaign, explains why supply chain compromise scales so effectively, and sets out the specific questions business owners must ask their web developers, IT providers, and managed service providers today. No patch can protect you from a script you load from someone else’s content delivery network, and no endpoint tool will flag an RMM agent it has been trained to trust. The NCSC has published supply chain guidance repeatedly; these campaigns demonstrate how rarely it is applied in practice.

• Intro Mauven frames the common vulnerability across today’s campaigns: reliance on third-party platforms that UK small businesses cannot audit, patch, or monitor in real time.
• Brevo Supply Chain Attack On 14 September 2026, attackers compromised Brevo’s infrastructure, injecting malicious JavaScript that silently installed WordPress backdoor plugins on admin machines and delivered ClickFix credential-harvesting overlays to visitors across over 100,000 customer sites.
• CTA Mauven asks listeners to follow the show and share it with colleagues who need the briefing.
• Clop Returns with a Custom Implant The Clop threat group is exploiting CVE-2026-12569 in PTC Windchill with a custom web shell built for rapid credential harvesting, database enumeration, and data exfiltration, targeting UK manufacturing and engineering businesses.
• Settra Ransomware and RMM Abuse Settra ransomware maintains persistence by installing MeshAgent, a legitimate remote monitoring tool that endpoint security trusts by default, making unauthorised access harder to detect.
• The Wider Pattern Mauven connects all three campaigns to the same structural weakness: shared platforms, scripts, and tools that businesses cannot directly control, and the persistent gap between available NCSC guidance and real-world application.
• Outro Mauven summarises the specific actions listeners must take today: audit Brevo-linked sites, confirm PTC Windchill patches, and ask MSPs which RMM agents are authorised and how unauthorised ones would be detected.

Two critical threats require immediate attention from UK businesses today. Cisco has disclosed an authentication bypass vulnerability in its Identity Services Engine with a maximum CVSS score of 10.0, and exploitation is already confirmed as active. ISE functions as a network gatekeeper for VPN, device compliance, and access control, making this vulnerability a direct path to your network perimeter. Separately, the GhostCode phishing technique weaponises Microsoft’s legitimate OAuth device code flow to bypass multi-factor authentication entirely. The attack arrives via business contact forms, presents victims with authentic Microsoft URLs, and produces valid session tokens that persist even after password resets. Analysis of ransomware activity in Japan reveals that 80 per cent of victims had capital under one billion yen, confirming that small and medium businesses are the majority of targets, not the exception. With Windows 11 24H2 reaching end of support in October 2026, unpatched endpoints remain a consistent entry point in post-breach analysis. This briefing provides specific actions for patching, MFA hardening, conditional access policies, and session revocation.

• Introduction Mauven introduces two urgent threats: a Cisco vulnerability with active exploitation and a phishing technique that bypasses MFA controls most organisations rely on.
• Cisco ISE Authentication Bypass (CVSS 10.0) Analysis of the critical Cisco Identity Services Engine vulnerability with confirmed active exploitation, explaining why network access control systems are high-value targets and providing immediate patching guidance.
• Call to Action Encouragement to follow the show and share with business owners and IT providers who need timely threat intelligence.
• GhostCode OAuth Device Code Phishing Detailed breakdown of the GhostCode phishing kit that abuses Microsoft’s OAuth 2.0 device authorisation flow to bypass MFA, including detection indicators and specific mitigation steps.
• Ransomware Targeting of Smaller Businesses Analysis of Cisco Talos data showing 80 per cent of ransomware victims in Japan were small and medium enterprises, challenging the assumption that smaller size reduces risk.
• Windows 11 24H2 End of Support Reminder that Windows 11 24H2 Home and Pro editions reach end of support in October 2026, with guidance on fleet assessment and update planning.
• Outro Recap of the two key takeaways: immediate patching and verification actions, and the structural reality that small businesses are primary ransomware targets.

CISA has confirmed active exploitation of a critical ConnectWise ScreenConnect vulnerability, the remote access tool used by countless UK IT providers to support small business clients. Attackers are targeting managed service providers to gain indirect access to entire client portfolios. Meanwhile, the GhostCode phishing campaign is bypassing traditional defences by abusing Microsoft’s legitimate OAuth device code flow, landing in inboxes through web contact forms and requiring no fake login pages. Finally, Google has patched a zero-day privilege escalation flaw in Pixel devices that was exploited in targeted attacks. This briefing explains why these threats matter to UK SMBs, what the attack patterns look like in practice, and what concrete actions business owners and IT managers should take today. Mauven MacLeod delivers the technical detail and the operational context that turns threat intelligence into defensible decisions.

• Introduction Mauven introduces two active threats targeting UK small businesses through legitimate infrastructure: a remotely exploited ScreenConnect flaw and an OAuth device phishing technique that bypasses traditional defences.
• ScreenConnect: CISA Confirms Active Exploitation CISA has added a critical ConnectWise ScreenConnect vulnerability to its Known Exploited Vulnerabilities catalogue. Attackers are targeting IT providers to gain indirect access to their SMB clients. Business owners are advised to verify their MSP has patched the tool and to understand the supply chain risk.
• Call to Action A reminder to follow the show and share the briefing with colleagues who need the information.
• GhostCode: OAuth Device Phishing eSentire has documented the GhostCode phishing kit, which abuses Microsoft’s OAuth device code flow to gain persistent access to Microsoft 365 accounts. The campaign impersonates procurement officers, uses web contact forms, and directs victims to legitimate Microsoft URLs, bypassing traditional phishing defences.
• Pixel Zero-Day Google’s September 2026 patch for Pixel devices includes a fix for a zero-day privilege escalation vulnerability exploited in targeted attacks. Organisations using Pixel devices should install the update immediately.
• Closing Remarks Mauven summarises the three practical actions listeners should take: verify ScreenConnect patch status with IT providers, brief staff on OAuth device code phishing indicators, and review OAuth app consents in Microsoft Entra admin centre.

Three active cybercriminal campaigns are exploiting trust in routine business systems. GrelosGTM injects payment skimmers into Google Tag Manager containers on compromised e-commerce sites, bypassing traditional file integrity checks and PCI compliance tools. Two IoT malware families, KATARU and Evooo1Bot, are scanning for unpatched edge devices using vulnerabilities dating back to 2007, turning compromised routers and network appliances into proxy infrastructure. Meanwhile, criminals are creating convincing fake versions of legitimate financial portals that surface in organic search results through typosquatting and Punycode manipulation. Each campaign targets a different attack surface, but all exploit the same underlying assumption: that familiar tools, devices, and search results are inherently trustworthy. Mauven MacLeod examines the behavioural incentives that make these attacks effective and outlines practical steps UK businesses can take today to audit their Google Tag Manager containers, verify firmware on internet-facing devices, and reduce social engineering risks through simple URL management practices.

• Introduction Overview of three active campaigns exploiting trust in marketing tools, network hardware, and search engine results.

Two active exploitation campaigns are affecting UK small businesses today. Ransomware operators are exploiting a critical WatchGuard Firebox vulnerability that was added to CISA’s Known Exploited Vulnerabilities catalogue in December 2025, yet remains unpatched in many deployments nine months later. The flaw allows remote, unauthenticated code execution on internet-facing devices. Separately, four China-aligned threat actors have adopted an identical Chrome and Windows zero-day exploit chain within days of each other, enabling full system compromise through a single malicious webpage visit. The BlueMoon exploit kit combines CVE-2026-85046 in Chrome’s V8 engine with CVE-2026-85880 in the Windows kernel. Patches are available for both campaigns. Additionally, Cisco Secure Firewall Management Center is under active exploitation via two vulnerabilities that grant administrative control, with possible connections to the Qilin ransomware group. Today’s briefing provides specific remediation steps for each threat and examines why a nine-month-old vulnerability continues to find victims, highlighting fundamental patch management failures across the UK SMB sector. Mauven frames the discussion around visibility, accountability, and the compression of exploitation windows in modern threat environments.

• Introduction Mauven opens the tenth of September 2026 briefing with two active exploitation events affecting UK small businesses: a nine-month-old WatchGuard vulnerability now used by ransomware operators, and a browser-based zero-day chain adopted by four state-aligned actors within days.
• WatchGuard Firebox Ransomware Exploitation CISA confirms ransomware gangs are actively exploiting a critical remote code execution flaw in WatchGuard Firebox appliances. The vulnerability was added to the KEV catalogue in December 2025, yet remains unpatched in many UK SMB deployments. Ransomware operators use automated scanning to find vulnerable devices. Mauven emphasises the need to verify firmware versions immediately and obtain written confirmation from managed service providers.
• Call to Action Mauven encourages listeners to follow the show and share it with colleagues who need daily threat intelligence.
• BlueMoon Chrome Zero-Day Exploit Chain Proofpoint and Volexity report on the BlueMoon exploit kit, which chains CVE-2026-85046 in Chrome’s V8 engine with CVE-2026-85880 in the Windows kernel. Four China-aligned threat actors adopted identical exploitation within days, suggesting coordinated or brokered tooling. The attack requires only visiting a compromised webpage and achieves full system compromise. Patches are available from Google and Microsoft’s September 2026 Patch Tuesday.
• Cisco Secure Firewall Management Center Exploitation Cisco Talos tracks active exploitation of CVE-2026-20079 and CVE-2026-20316 in Cisco Secure Firewall Management Center, which together grant administrative control. Possible connections to the Qilin ransomware group are noted. The vulnerability primarily affects mid-market professional services and managed security provider infrastructure.
• Patch Management Reality Check Mauven examines the operational reality of three network security products under active exploitation in the same news cycle. The continued exploitation of a nine-month-old WatchGuard vulnerability demonstrates that patch management is treated as optional despite NCSC guidance. The core issue is visibility: organisations must be able to answer which internet-facing devices and applications were updated in the last thirty days.
• Closing and Practical Takeaway Mauven summarises the immediate action items: confirm WatchGuard Firebox firmware is current and verify Chrome and Windows updates are applied across all devices. Listeners are encouraged to demand specific answers from IT providers, not vague reassurances.

Three separate incidents this week reveal a single, critical vulnerability across UK small businesses: access management. Microsoft Threat Intelligence has confirmed an active campaign exploiting Teams external collaboration to impersonate IT helpdesk staff, tricking employees into installing remote access tools that deploy malicious payloads. Meanwhile, new analysis shows that resetting passwords after infostealer compromise leaves authenticated session tokens active, allowing attackers continued access for days. A separate case study documents a terminated employee retaining elevated access long enough to cause hundreds of thousands in damages, purely because no formal offboarding checklist existed. The technical controls to prevent all three scenarios are available and documented. What is missing is operational discipline: caller verification before granting remote access, session revocation alongside password resets, and comprehensive leaver access audits. This episode provides specific, actionable guidance for small businesses without dedicated security teams, walking through the configuration changes, staff briefings, and process checklists required to close these gaps before they are exploited.

• Introduction Overview of three incidents that all point to access management as the primary UK SMB vulnerability right now, with context from yesterday’s coverage and Microsoft’s new formal confirmation.
• Attackers Impersonating IT Helpdesk via Microsoft Teams Detailed breakdown of the confirmed Microsoft Teams helpdesk impersonation campaign, including the full technical chain from initial contact to lateral movement, and specific configuration and process changes required to mitigate the risk.
• Call to Action Brief listener engagement prompt.
• Infostealer Sessions: The MFA Problem Nobody Is Talking About Analysis of the session token problem in infostealer incidents, why password resets alone are insufficient, and the specific session revocation steps required in Microsoft 365 and other platforms.
• The Leaver Who Kept Access Case study of a terminated employee retaining elevated access due to absent offboarding processes, with practical guidance on access audits and leaver checklists for small businesses.
• The Pattern Connecting All Three Synthesis of the common access management gap across all three incidents and the operational discipline required to close it.

Nearly 22,000 Microsoft Exchange servers remain unpatched for a critical authentication bypass vulnerability allowing complete mailbox takeover. PaperCut print management software, deployed across thousands of UK offices, is actively exploited for data theft days after a patch was released. A 33-hour BGP hijack of Softaculous infrastructure may have poisoned the hosting supply chain for small business websites. This briefing provides specific verification steps for IT providers, explains why the window between patch release and exploitation continues to shrink, and connects these incidents to wider supply chain and social engineering threats including Teams vishing campaigns and fake CAPTCHA attacks. For UK small businesses running on-premises Exchange, PaperCut installations, or shared hosting websites, today’s combination represents direct and immediate exposure requiring same-day action.

• Introduction Three active threats with direct paths into UK small business environments: 22,000 unpatched Exchange servers, active PaperCut exploitation for data theft, and a 33-hour BGP hijack of Softaculous infrastructure.
• CVE-2026-62911: Exchange Authentication Bypass High-severity vulnerability allowing unauthenticated attackers to hijack all user mailboxes on 22,000 internet-exposed Exchange servers. Verification steps for IT providers and the organisational failure behind persistent Exchange patching delays.
• Listener Call to Action Encouragement to follow the show and share with those running on-premises Exchange or shared hosting sites.

Manchester Airports Group has suffered a confirmed data breach larger than initially disclosed, with 86GB of validated customer and travel records now in threat actor hands. UK businesses with corporate travel through Manchester, Stansted, or East Midlands face immediate phishing risk. Meanwhile, the TerminalFix campaign bypasses email defences entirely by tricking users into executing malicious PowerShell commands through fake Cloudflare CAPTCHA overlays on compromised websites. Microsoft Defender’s broken status alerts, with official guidance to ignore warnings, create a window where genuine malware could disable endpoint protection undetected. Mauven examines the gap between initial breach disclosures and validated impact, the social engineering techniques that route around traditional defences, and why session token theft from infostealer malware cannot be resolved by password resets alone. Practical guidance includes staff briefings on travel data targeting, application control policies for Windows Terminal, and management-layer monitoring to compensate for unreliable user-facing alerts.

• Introduction Overview of three active threats affecting UK businesses: a confirmed airport breach with validated stolen data, a social engineering campaign designed to bypass email defences, and a Microsoft Defender issue creating alert fatigue.
• Manchester Airports Group Breach FulcrumSec claims 86GB data theft from Manchester Airports Group, with independently validated customer and travel records. Analysis of the disclosure gap, targeting risks for corporate travel, and practical steps for businesses with MAG connections.
• Call to Action Encouragement to follow the show and share the episode with UK business contacts who need awareness of the Manchester Airports situation.
• TerminalFix Campaign Microsoft’s analysis of TerminalFix, a ClickFix variant using fake Cloudflare CAPTCHA overlays on compromised websites to trick users into executing malicious PowerShell commands through Windows Terminal, bypassing email-based defences entirely.
• Microsoft Defender Alert Fatigue Latest Defender update causes false ‘antivirus is turned off’ alerts, with Microsoft advising users to ignore warnings. Implications for security culture and the need for management-layer monitoring during the issue.
• Infostealer Session Theft Anthropic confirms Claude session token theft via infostealer malware, illustrating broader principle that stolen session cookies remain valid after password resets and require explicit session revocation across all platforms.
• Closing Summary of common theme across stories: existing defences do not address current attack vectors. Three immediate actions for UK businesses: brief staff on MAG breach targeting, educate on terminal-based social engineering, and implement management-layer Defender monitoring.

This episode examines three active threats targeting UK small businesses through infrastructure that is often managed inattentively. PaperCut print management servers face active zero-day exploitation with no official vendor patch available, forcing organisations to choose between unvalidated emergency fixes or taking systems offline. A Microsoft Teams vishing campaign, running since January 2026, uses social engineering and the legitimate Windows Quick Assist tool to deploy the GoGRPC backdoor for ransomware operators. Research into ZBT router firmware reveals three pre-installed implants, including DARKLANTERN, an unauthenticated backdoor offering root shell access. The episode also covers critical ServiceNow vulnerabilities, over 8,300 unpatched Gitea instances facing active exploitation, and CISA’s observation that most exploited vulnerabilities in 2026 should have been eradicated decades ago. The common thread is infrastructure that organisations do not actively monitor: print servers, router firmware, and remote access tools that staff use without scrutiny. Mauven provides specific, actionable guidance for each threat, emphasising that the surfaces receiving least attention from defenders are those being studied most carefully by attackers.

• Introduction Overview of three active threats targeting infrastructure that UK small businesses manage inattentively: a print server zero-day, an eight-month Teams vishing campaign, and firmware implants in routers.
• PaperCut Zero-Day: Active Exploitation, No Official Patch PaperCut print management servers face active zero-day exploitation with no validated vendor patch. The software, widely deployed in UK SMBs, has administrative access to networked devices and was previously exploited by ransomware groups in 2023. Organisations must choose between applying an unvalidated emergency patch or taking servers offline.
• Call to Action Brief listener engagement request.
• Microsoft Teams Vishing: GoGRPC Backdoor and the Ransomware Pipeline Zscaler research details an eight-month campaign using Microsoft Teams vishing and the legitimate Windows Quick Assist tool to deploy the GoGRPC backdoor. Attackers impersonate IT support, gain remote access, and sell network access to ransomware operators. The attack exploits normalised IT support behaviours.
• Firmware Implants in the Supply Chain: ZBT Routers VulnCheck identifies three firmware implants in ZBT routers distributed globally: SPEAKINGSTONE, DARKLANTERN, and ENDLESSDOORS. DARKLANTERN provides unauthenticated root shell access via UDP port 9992. The implants were present in firmware before devices reached customers, representing a hardware-layer supply chain compromise.
• ServiceNow, Gitea, and the CISA Observation Three maximum-severity vulnerabilities patched in ServiceNow AI Platform. Over 8,300 internet-exposed Gitea instances remain unpatched against actively exploited remote code execution flaws. CISA notes that most exploited vulnerabilities in 2026 should have been eradicated decades ago, citing organisational culture failures.
• Closing Remarks The common thread across all threats is infrastructure inattention. Print servers, router firmware, and remote access tools that organisations do not actively monitor are precisely the surfaces attackers study most carefully. Practical guidance emphasises active management of unglamorous infrastructure.

Three maximum-severity vulnerabilities have been disclosed in Ubiquiti’s UniFi network products, all exploitable remotely without authentication. Separately, CISA has confirmed active exploitation of a critical code injection flaw in Gitea, the self-hosted Git service widely used for internal code repositories. Both disclosures highlight a persistent gap in how UK businesses secure infrastructure that sits behind the public perimeter. UniFi kit manages internal networks and physical security systems across thousands of SMBs, yet firmware updates often lag months behind current versions. Gitea servers hold development code, credentials, and API keys, but are frequently treated as lower-priority assets despite their access to production environments. The observed Gitea exploitation involves cryptominer deployment, but the real risk is remote code execution on systems that touch sensitive infrastructure. This episode examines why trusted infrastructure receives less scrutiny than customer-facing systems, and why that gap creates exploitable exposure. Mauven provides specific patch guidance, incident response steps, and asset inventory priorities for both vulnerabilities.

• Intro Mauven introduces episode thirty-nine, focusing on infrastructure vulnerabilities that receive insufficient security attention despite supporting critical business operations.
• Ubiquiti UniFi: Three Max-Severity Flaws Three maximum CVSS score vulnerabilities disclosed in UniFi Network Application and UniFi Protect, all exploitable remotely without authentication. Covers authentication bypass and command injection risks, UK SMB deployment patterns, and immediate patching requirements.
• CTA Brief call to action encouraging listeners to follow the podcast and share with colleagues managing network infrastructure.
• Gitea RCE: CISA Confirms Active Exploitation CISA adds critical Gitea code injection vulnerability to Known Exploited Vulnerabilities catalogue following confirmed cryptominer deployment. Discusses risks to self-hosted Git repositories, credential exposure, and the need for log analysis and repository auditing.
• The Trusted Infrastructure Problem Analysis of why infrastructure supporting operations rather than serving customers receives less security scrutiny, creating exploitable gaps. Covers NCSC guidance on vulnerability management and notes a ClickFix phishing campaign using npm mirror infrastructure.
• Outro Summary of patch requirements and asset review priorities for both UniFi and Gitea. Closing remarks and episode credits.

Three active threats demand immediate attention from UK small businesses today. ClickFix social engineering campaigns have matured into a multi-vector malware ecosystem using MSI packages, NodeJS execution, and fake CAPTCHA lures to deliver persistent backdoors across Windows and macOS systems. Attackers are abusing legitimate Windows tools and storing command-and-control addresses in blockchain smart contracts, making traditional network defences less effective. Check Point has confirmed active exploitation of CVE-2026-16232, a critical authentication bypass in SmartConsole that grants unauthenticated remote attackers full administrative access to firewall management servers. Organisations using managed service providers for firewall infrastructure need specific answers about exposure windows and remediation status. A remote code execution vulnerability in Zimbra Collaboration Suite has already compromised over 270 email servers, with the campaign ongoing. This episode provides actionable guidance on endpoint monitoring configuration, management server security reviews, and supplier due diligence for email hosting platforms. None of these threats are theoretical. All three are actively exploiting UK organisations today.

• Introduction Mauven introduces three active threats affecting UK small businesses: a mature social engineering malware ecosystem, a critical firewall management authentication bypass under active exploitation, and an email server vulnerability with over 270 confirmed compromises.
• ClickFix: The Social Engineering Technique That Grew Up Analysis of ClickFix malware campaigns using MSI packages with DLL sideloading, NodeJS execution, and fake CAPTCHA lures. Coverage includes PavinLoader’s blockchain-based command-and-control infrastructure, cross-platform macOS variants, and fraudulent SysScan websites. Practical guidance on endpoint protection configuration and staff awareness training.
• Call to Action Encouragement to follow the show and share threat intelligence with professional networks to close the gap between awareness and action.
• Check Point SmartConsole: Authentication Bypass Under Active Exploitation Detailed examination of CVE-2026-16232 and accompanying privilege escalation vulnerabilities in Check Point SmartConsole. Focus on exploitation conditions, attack chains, and specific questions UK SMBs must ask managed service providers about exposure and remediation.
• Zimbra RCE: 270 Servers Down, Campaign Ongoing Coverage of the ongoing Zimbra Collaboration Suite remote code execution campaign affecting over 270 instances. Discussion of supply chain risks through managed hosting providers and the operational impact of email server compromise. Guidance on verification and patching.
• Closing Remarks Mauven identifies the common thread across all three threats: attackers exploiting configuration gaps and awareness failures rather than extraordinary techniques. Recap of actionable steps for endpoint monitoring, supplier verification, and staff training.

This episode examines three active threats demanding immediate attention from UK small businesses. First, a zero-click remote code execution vulnerability in Zimbra Collaboration Suite (CVE-2025-66376) under active exploitation by Russian-linked threat actors, with a three-day federal patch deadline from CISA. Second, an authentication bypass flaw in Check Point SmartConsole (CVE-2026-16232) allowing unauthenticated remote attackers full administrative access to exposed management servers. Third, a vishing and device code phishing campaign by the Helix data extortion group that requires no malware and leaves minimal forensic trace. The episode emphasises that all three threats exploit the gap between what organisations have configured and what they actually review. Practical actions include patching Zimbra immediately, verifying Check Point management interfaces are IP-restricted, enabling Microsoft 365 unified audit logging, and training staff on device code phishing recognition. The common thread is organisational discipline: knowing what is running in your environment, how it is configured, and whether anyone is reviewing the evidence of activity within it.

• Introduction Mauven introduces three threats for 24 August 2026: two confirmed, actively exploited vulnerabilities with patches available, and a social engineering campaign that leaves no malware trace. The third threat is identified as the most dangerous for UK small businesses reliant on endpoint detection alone.
• Zimbra Zero-Click RCE Under Active Exploitation CISA has added CVE-2025-66376, a zero-click remote code execution flaw in Zimbra Collaboration Suite, to its Known Exploited Vulnerabilities catalogue with a three-day federal patch deadline. The vulnerability is being exploited by Russian-linked threat actor Void Blizzard (LAUNDRY BEAR) in a systematic credential harvesting operation targeting government, defence, transportation, and financial sector organisations across NATO member states. UK small businesses, particularly legal firms, accountancy practices, and professional services running on-premises email, must patch immediately, verify Zimbra deployment status, restrict internet access if patching cannot occur immediately, and review access logs for anomalous activity.
• Call to Action Listeners are encouraged to follow the show and share the briefing with colleagues who can act on the information presented.
• Check Point SmartConsole Authentication Bypass Check Point has confirmed active exploitation of CVE-2026-16232, an authentication bypass vulnerability in SmartConsole that allows unauthenticated remote attackers full administrative access to exposed Management Servers. Exploitation has been confirmed against customers with management interfaces exposed to the internet without IP restrictions. UK organisations using Check Point products must apply security updates immediately, verify all management interfaces are IP-restricted with documentation, review access logs for authentication attempts from unexpected sources, and confirm managed service providers have patched all deployments.
• Helix Vishing and Device Code Phishing ReliaQuest has documented a data extortion group named Helix running a three-stage attack requiring no malware: vishing calls impersonating managers using open-source research from LinkedIn and company websites, device code phishing directing employees to enter codes into legitimate Microsoft authentication pages to grant attackers persistent access tokens, and automated SharePoint exfiltration. The campaign leaves no endpoint detection evidence and is only visible in Microsoft 365 unified audit logs. UK small businesses must brief all staff on device code phishing, establish verbal verification procedures for credential-related requests, enable unified audit logging in Microsoft 365, and consider Conditional Access policies restricting device code authentication flows.
• The Pattern This Week All three threats exploit the gap between what organisations have configured and what they have reviewed. Zimbra instances not audited since deployment, management interfaces opened for remote access and never locked down, and Microsoft 365 audit logs not being read represent ordinary accumulated drift rather than exotic failures. The adversaries target organisations that have not implemented basic controls, and the discipline required to close these gaps is organisational rather than technical.
• Conclusion The practical takeaway is to answer three questions immediately: is Zimbra running anywhere in your environment, is any network device management interface accessible from the internet without IP restriction, and is unified audit logging enabled in your Microsoft 365 tenant. If the answers are unknown, organisations must find out today.

This episode examines two unconnected but similarly exploitative campaigns targeting UK small businesses in August 2026. The first, SynkLoader, uses Microsoft Teams to impersonate IT helpdesk staff, delivering memory-resident malware through plausible maintenance requests. The attack succeeds because default Teams external access settings allow unrestricted messages from unknown tenants. The second involves a coordinated supply chain attack against three legitimate Rust programming language packages, injecting malicious code through a typosquatted dependency that executes during software builds. Both campaigns exploit trust in familiar channels rather than technical vulnerabilities. Mauven MacLeod explains why these attacks work, what they reveal about default configurations in SMB environments, and provides actionable steps: restricting Teams external federation, establishing clear IT contact protocols, auditing Rust dependencies for the malicious proc-macro1 package, and questioning software vendors about supply chain verification. The episode emphasises that effective defence requires deliberately changing insecure defaults, not advanced security tooling.

• Introduction Mauven introduces two active campaigns targeting UK small businesses through trusted channels: a Teams-based helpdesk impersonation attack and a Rust programming language supply chain compromise. Both exploit default configurations rather than technical vulnerabilities.
• SynkLoader: When Your IT Helpdesk Comes to You Analysis of SynkLoader malware delivered via Microsoft Teams helpdesk impersonation. The attack uses MSI installers to deploy multi-language, memory-resident malware that bypasses endpoint detection, establishes command-and-control access, and captures credentials through fake lock screens. Succeeds because default Teams external access settings allow unrestricted external messages.
• Call to Action Encouragement to follow the show and share with colleagues who would benefit from daily threat intelligence briefings.
• Rust Supply Chain: The Dependency You Did Not Know You Had Examination of a coordinated supply chain attack against three legitimate Rust packages through a typosquatted dependency called proc-macro1. Malicious code executed during software builds, potentially compromising both bespoke software and commercial products. Highlights the gap in SMB software procurement processes around supply chain verification.
• The Wider Picture Connects both campaigns through their exploitation of trust in familiar channels and legitimate-seeming sources. Emphasises that effective attacks against small businesses rely on familiarity rather than technical sophistication, and that changing insecure defaults requires deliberate decisions.
• Closing Recap of practical actions: verify Teams external federation settings and question IT providers about software supply chain verification processes. Two questions that reveal the current security posture.

CISA has confirmed active exploitation of a critical MLflow vulnerability, demanding immediate action from any organisation running AI or machine learning infrastructure. The server-side request forgery flaw allows attackers to access internal systems, and deployment patterns mean the platform often sits outside normal security review cycles. Separately, Citrix has issued an urgent advisory for NetScaler Gateway and ADC vulnerabilities, with language reflecting high exploitation likelihood. The perimeter-facing nature of these widely deployed remote access solutions makes them priority targets. Finally, the Manic Android banking trojan is spreading across Europe with a relay-based exfiltration capability that partially defeats network controls, raising BYOD security questions for UK small businesses. The NCSC has also published new guidance on managing agentic AI cyber risk, connecting to broader concerns about autonomous systems acting on behalf of users without adequate security review.

• Introduction Mauven opens with three stories requiring immediate action: a CISA-confirmed active exploitation, an urgent Citrix advisory, and a European banking malware threat relevant to UK businesses.
• MLflow Under Active Exploitation CISA adds MLflow to the Known Exploited Vulnerabilities catalogue following confirmed active attacks. The server-side request forgery vulnerability affects AI and machine learning deployments that often sit outside normal security review cycles, creating exposure many organisations may not be aware of.
• Call to Action Listeners are encouraged to follow the show and share the briefing, particularly with those managing IT for small businesses who need urgent awareness of the MLflow exploitation.
• Citrix NetScaler Emergency Advisory Citrix issues urgent patching guidance for NetScaler Gateway and ADC vulnerabilities. The perimeter-facing nature of these widely deployed products, combined with Citrix’s deliberate use of emergency language, signals high exploitation risk requiring immediate verification with IT providers.
• Manic Android Malware in Europe The Manic banking trojan spreads across Europe with relay-based exfiltration capability that routes stolen data through nearby infected devices, partially defeating network controls. BYOD practices in UK small businesses create exposure when personal Android devices access work accounts.
• NCSC Guidance on Agentic AI The NCSC publishes guidance on managing cyber risk from autonomous AI systems that act on behalf of users. Prompt injection attacks against agentic AI tools represent an escalating threat as these systems gain access to business accounts and services.
• Closing Mauven connects the common thread across all stories: security gaps emerge when deployment outpaces security review. The practical priority is knowing what runs in your environment, who manages it, and how responsibility is verified.

This episode covers three active threats with credible paths to UK small businesses. First, CISA has added a critical Windows IKE Extension remote code execution vulnerability to its Known Exploited Vulnerabilities catalogue, confirming active exploitation against network-reachable systems. Second, Clop ransomware has returned with purpose-built tooling targeting PTC Windchill in manufacturing supply chains, deploying custom web shells designed for credential harvesting and data exfiltration. Third, the Mirage2FA phishing-as-a-service platform is bypassing multifactor authentication through adversary-in-the-middle session token theft, with over four thousand confirmed Microsoft 365 victims. Mauven explains the technical mechanisms behind each threat, identifies the specific organisations at risk, and provides actionable steps that require no budget approval: verifying Windows patch status for IKE Extension, questioning manufacturing suppliers about Windchill patching, and reviewing Microsoft 365 conditional access policies to detect session anomalies. The episode also notes FBI confirmation of Medusa ransomware breaching over five hundred US critical infrastructure organisations using living-off-the-land techniques. All three primary threats demonstrate that speed of response, supplier questioning, and configuration review matter more than technology spending for most small business cyber resilience.

• Introduction Mauven introduces three threats with credible UK small business impact: a Windows vulnerability under active exploitation, Clop ransomware with custom tooling, and an MFA-bypassing phishing platform.
• Windows IKE Extension RCE: CISA KEV Addition CISA has added a critical Windows IKE Extension remote code execution vulnerability to its Known Exploited Vulnerabilities catalogue. The flaw is network-reachable, requires no authentication, and allows arbitrary code execution. Mauven explains why active exploitation status demands immediate Windows patch verification, particularly for organisations using Windows-based VPN solutions.
• Support the Show Brief call to action encouraging listeners to follow the show and share with business owners who need operational threat intelligence.
• Clop Returns with Purpose-Built Tooling Clop ransomware is targeting PTC Windchill in manufacturing and engineering supply chains using custom-developed web shells. ReliaQuest analysis confirms the toolkit includes credential harvesting, database enumeration, and Java-based exfiltration components. Mauven explains the supply chain exposure risk and recommends questioning suppliers about Windchill patching status.
• Mirage2FA Phishing-as-a-Service Bypasses MFA Mirage2FA operates as an adversary-in-the-middle proxy, capturing authenticated Microsoft 365 session tokens after users complete MFA. ANY.RUN analysis identifies over four thousand victims. Mauven explains why MFA alone is insufficient without conditional access policies detecting impossible travel and anomalous session use.
• Medusa Ransomware Context FBI confirms Medusa ransomware has breached over five hundred US critical infrastructure organisations since June 2021 using phishing, unpatched vulnerabilities, and living-off-the-land techniques. Mauven notes the tactics are internationally relevant and the confirmed victim count likely understates true impact.
• Summary and Actions Three actions requiring no budget: verify Windows IKE Extension patch deployment, question manufacturing suppliers about PTC Windchill patching, and review Microsoft 365 conditional access configuration to detect session token theft. Mauven emphasises that difficulty having these conversations is itself diagnostic of resilience gaps.

Two Microsoft vulnerabilities demand immediate attention from UK small businesses running Windows endpoints and Microsoft 365. CISA has confirmed active ransomware exploitation of the Windows Task Host privilege escalation flaw, four months after its initial disclosure. This vulnerability allows attackers who have gained initial access to escalate to system-level privileges, enabling lateral movement and full ransomware deployment. Separately, Microsoft has disclosed CVE-2026-24301, a command injection vulnerability in Copilot that enables information disclosure across the entire Microsoft 365 data estate. Because Copilot operates within user permission contexts, the vulnerability exposes whatever data those users can access, including financial records, HR files, and confidential client information. Researchers have also documented C2Looper, a Rust-based backdoor that uses GitHub for command-and-control traffic and connects to ClickFix infection chains. Together, these developments illustrate a complete ransomware kill chain from initial access through privilege escalation to deployment. Organisations must confirm Windows patch status today, review Copilot access permissions against the principle of least privilege, and brief staff on ClickFix lures that present as fake browser error messages.

• Introduction Overview of two Microsoft vulnerabilities affecting Windows endpoints and Microsoft 365, both requiring immediate action. CISA has confirmed ransomware exploitation of the Windows Task Host flaw, whilst Microsoft has disclosed a command injection vulnerability in Copilot.
• Windows Task Host Ransomware Exploitation Analysis of the Windows Task Host privilege escalation vulnerability, now confirmed by CISA as actively exploited by ransomware groups. Explains how attackers use the flaw to escalate from low-privilege access to system-level control, enabling lateral movement and full estate compromise. Four months have passed since disclosure.
• Call to Action Encouragement to follow the show and share it with others who need threat intelligence information.
• CVE-2026-24301 Microsoft Copilot Command Injection Examination of the newly disclosed command injection vulnerability in Microsoft Copilot. Explains how Copilot’s deep integration with Microsoft 365 data means the vulnerability exposes entire organisational data estates through user permission contexts. Addresses the risk of default enablement and the need for permissions audits.
• C2Looper and Ransomware Delivery Chains Overview of C2Looper, a Rust-based backdoor that uses GitHub for command-and-control traffic, and its connection to ClickFix infection chains. Describes the complete ransomware kill chain from initial access through privilege escalation, emphasising the importance of staff awareness training on ClickFix techniques.
• Conclusion Practical summary of required actions: confirm Windows patch status immediately, review Copilot access permissions, apply least privilege principles, and brief staff on ClickFix lures this week.

Three distinct threat campaigns broke on 14 August 2026, and each one targets the same vulnerability: supplier and third-party infrastructure. Clop ransomware claimed 89GB of Shell data via managed file transfer platforms, continuing a six-year pattern of targeting MFT tools across supply chains. ShinyHunters exposed 1.6 million RingCentral accounts while simultaneously running OAuth abuse campaigns against Salesforce and other SaaS platforms, weaponising legitimate integrations and voice phishing. A maximum-severity SAP Commerce Cloud vulnerability moved from patch release to active exploitation in just three days. Meanwhile, supplier breaches at the Crown Office and Procurator Fiscal Service in Scotland and Trezor’s logistics partner reinforce the same pattern: organisations with sound internal controls are being compromised through third-party infrastructure they don’t directly manage. This briefing explains why managed file transfer platforms, OAuth connections, and unpatched supplier software represent the dominant attack surface in 2026, and provides actionable steps for UK small businesses to identify and close these exposure gaps before threat actors exploit them.

• Introduction Three separate threat streams reveal a unified pattern: organisations with well-managed internal environments are being compromised through supplier infrastructure, SaaS integrations, and third-party software.
• Clop Claims Shell: The Method Is Six Years Old Clop ransomware claimed 89GB of Shell data via PTC FlexPLM and Windchill platforms. Team Cymru analysis shows Clop has run nine campaigns over six years, systematically targeting managed file transfer tools across supply chains.
• Call to Action Encouragement to follow the show and share with colleagues who may underestimate their exposure to supplier-based threats.
• ShinyHunters Pivots from Data Theft to SaaS Infiltration ShinyHunters breached RingCentral, exposing 1.6 million accounts, while simultaneously running OAuth abuse campaigns against Salesforce and other SaaS platforms using voice phishing, supply chain compromise, and credential theft.
• SAP Commerce Cloud: Maximum Severity, Already Exploited A maximum-severity remote code execution vulnerability in SAP Commerce Cloud moved from patch release to active exploitation in three days, compressing response windows and exposing retailers and e-commerce operators.
• The Pattern Underneath Today’s Stories Clop, ShinyHunters, and the SAP campaign all exploit third-party and supplier exposure. Additional breaches at Crown Office Scotland and Trezor’s logistics partner reinforce that supplier risk is the dominant attack surface in 2026.
• Closing Practical takeaways: map supplier access, audit OAuth connections, patch on severity rather than schedule, and brief staff on voice phishing tactics targeting legitimate application approval processes.

Mauven MacLeod presents today’s Threat Analysis, focusing on pressing cyber threats faced by UK small and medium businesses. She explores two major issues: vishing attacks exploiting Microsoft Teams and vulnerabilities in WordPress. Vishing attacks target companies through Microsoft Teams, where attackers impersonate IT helpdesk staff and deploy the GoGRPC backdoor. This can lead to ransomware attacks, compromising sensitive company data. Mauven emphasises the importance of staff awareness and technological safeguards to mitigate risks. The episode also highlights critical vulnerabilities in WordPress Core, affecting versions 6.9.0 to 7.0.1.

Three critical threats demand immediate attention today. A remote code execution vulnerability in ServiceNow’s AI Platform (CVE-2026-6875) is now actively exploited in the wild, requiring urgent patch verification from direct users and managed service providers alike. Meanwhile, a vishing campaign running since April has been successfully defeating Microsoft 365 passkey enrolment through carefully scripted social engineering, targeting UK SMBs who adopted phishing-resistant MFA but failed to brief staff on the human attack vector. The third story examines FortiBleed, an industrial-scale FortiGate credential harvesting operation exposed when attackers left their staging server accessible, revealing 36 rented GPUs running distributed password cracking as a production workflow. The episode also covers the Cruciferra crypter service, which offers high-quality endpoint evasion as a purchased feature, and the Hugging Face breach involving an autonomous AI agent. Each story includes specific, actionable guidance for UK organisations, with particular emphasis on the ServiceNow vulnerability requiring same-day verification from users and their supply chain.

• Introduction Mauven flags three threats requiring immediate action, particularly a ServiceNow vulnerability that has moved from patch-available to actively exploited. The episode will cover required responses for ServiceNow users, Microsoft 365 passkey vishing, and industrial-scale FortiGate credential harvesting.
• CVE-2026-6875: ServiceNow AI Platform RCE Under Active Exploitation Critical remote code execution vulnerability in ServiceNow AI Platform confirmed under active exploitation. Direct users must verify patch status immediately. Indirect exposure through managed service providers presents significant risk to UK SMBs. Specific guidance provided on what questions to ask providers and when patch confirmation is required.
• Call to Action Brief encouragement to follow the show and share with colleagues who need the briefing.
• O-UNC-066: Vishing Actors Defeating Microsoft 365 Passkey Enrolment Campaign active since April uses phone-based social engineering to register attacker-controlled passkeys to victim Microsoft 365 accounts. Attackers use domains containing ‘passkey’, impersonate Microsoft support, and guide targets through fake enrolment while simultaneously registering their own credentials. Three-part mitigation: restrict enrolment policies in Entra, brief staff on the attack pattern, and focus training on reception and finance staff most likely to receive calls.
• FortiBleed: Industrial-Scale VPN Credential Harvesting Exposed attacker staging server reveals large-scale FortiGate credential harvesting using 36 rented GPUs for distributed password cracking. Operation uses credential reuse, brute force, and GPU-accelerated hash cracking as an industrial workflow. Likely feeds initial access broker market serving ransomware operators. Guidance provided on verifying patch status, rotating credentials, and reviewing authentication logs.
• Also on the Radar Two additional items: Cruciferra crypter service offering high-quality endpoint evasion including BYOVD-based EDR tampering as a purchased feature, and Hugging Face breach involving autonomous AI agent access to production infrastructure and credentials. Both items flag direction of travel rather than immediate operational response.
• Closing Summary Recap of required actions: ServiceNow patch verification today, Microsoft 365 Entra policy review and staff briefing on vishing, FortiGate patch status and credential rotation. Emphasises that attackers operate at industrial scale while effective defences require consistent follow-through on straightforward measures.

CISA added critical Fortinet FortiSandbox vulnerabilities to its Known Exploited Vulnerabilities catalogue following confirmed in-the-wild exploitation. The US federal patching deadline is Sunday, but active exploitation means UK organisations should treat this as immediate priority. A newly published Windows local privilege escalation vulnerability called LegacyHive works on fully patched systems with no fix available, creating serious risk when combined with active ClickFix campaigns delivering initial access. ClickFix techniques now support at least five concurrent malware operations including ACR Stealer, Starland RAT, TELEPUZ, Potemkin Loader, and TTF campaign payloads. A Huntress case study documents how one ClickFix compromise spread to eleven hosts before detection. The episode provides specific, actionable guidance for SMBs: verify FortiSandbox patch status with IT providers today, brief staff on ClickFix lures immediately, review user permissions to execute scripts, and ensure endpoint detection monitors for HTA execution and PowerShell spawning from browser processes. The convergence of mature exploit infrastructure, public zero-day proof-of-concept, and active campaigns targeting European users represents a significant immediate threat to UK small business networks.

• Introduction Mauven opens the seventeenth of July briefing with three urgent stories. Two require immediate technical action before the weekend, whilst the third demands procedural response to an unpatched vulnerability.
• FortiSandbox Active Exploitation CISA confirmed active exploitation of critical FortiSandbox command injection vulnerabilities, ordering US federal agencies to patch by Sunday. FortiSandbox is a threat analysis appliance, not the firewall, creating particular concern as the security tool itself becomes attack surface. Guidance covers immediate patching requirements, how to verify MSP compliance, and the importance of asset inventory for unknown Fortinet deployments.
• Call to Action Brief appeal to follow the show and share with colleagues who need threat intelligence.
• LegacyHive Zero-Day Vulnerability A public proof-of-concept for Windows local privilege escalation called LegacyHive works on fully patched systems with no available fix. The vulnerability requires initial access first, which current ClickFix campaigns are actively providing across European targets. Defence recommendations focus on preventing initial compromise through application allow-listing, endpoint detection configuration, and staff awareness of ClickFix techniques.
• ClickFix Campaign Infrastructure At least five distinct malware operations now use ClickFix delivery techniques, including ACR Stealer, Starland RAT, TELEPUZ, Potemkin Loader, and TTF campaign payloads. A detailed Huntress case study shows one ClickFix compromise spreading to eleven hosts. Practical guidance includes immediate staff briefing, permission reviews to block arbitrary script execution, and verification that managed detection providers monitor relevant observable behaviours.
• Conclusion The convergence of mature ClickFix infrastructure, public Windows zero-day exploitation capability, and continuing Fortinet vulnerability exploitation represents the gap between published guidance and implemented defences. Two immediate actions: verify FortiSandbox patch status and brief staff on ClickFix lures before Friday.

This episode examines three contemporary threats exploiting trusted channels. Following the sentencing of two Scattered Spider members for the Transport for London breach, we analyse why social engineering remains devastatingly effective against organisations of all sizes. We then review a Russian campaign distributing trojanised WebEx and Zoom installers delivering Starland RAT, demonstrating how legitimate software becomes an attack vector. Finally, we cover the AsyncAPI npm supply chain compromise, where GitHub Actions vulnerabilities enabled injection of Miasma v3 worm into packages with valid provenance attestations. The common thread: attackers succeed not through technical brilliance, but by exploiting routine trust in familiar processes. We provide actionable guidance on helpdesk authentication procedures, software download verification, and dependency chain auditing. Additional coverage includes CISA’s Oracle E-Business Suite KEV listing and the approaching Windows 10 end-of-support deadline. Presented by Mauven MacLeod with behavioural analysis and concrete defensive measures for UK small businesses.

• Introduction Opening remarks establishing the episode’s central theme: trusted channels being weaponised through social engineering, trojanised software, and compromised dependencies.
• Scattered Spider Sentencing Analysis of two British Scattered Spider members receiving five-and-a-half-year sentences for the Transport for London breach, focusing on the social engineering techniques used and practical implications for SMB helpdesk procedures.
• Call to Action Audience engagement request encouraging listeners to follow the show and share with business owners.
• Trojanised WebEx and Zoom Examination of Russian actor UAT-11795 distributing backdoored collaboration software installers through phishing and search poisoning, delivering Starland RAT with credential theft and cryptocurrency targeting capabilities.
• AsyncAPI npm Supply Chain Compromise Technical breakdown of the AsyncAPI organisation compromise via GitHub Actions vulnerability, resulting in Miasma v3 worm delivery through four npm packages with valid provenance attestations and novel execution timing.
• Also on the Radar Brief coverage of CISA’s Oracle E-Business Suite KEV addition and the approaching Windows 10 end-of-support deadline for Home and Pro editions.
• Closing Remarks Summary emphasising verification over assumption, with specific guidance on questioning helpdesk authentication procedures.

On 15 July 2026, Mauven MacLeod examines three active threats facing UK organisations. CISA has added three Microsoft SharePoint Server vulnerabilities to its Known Exploited Vulnerabilities catalogue following confirmed active exploitation targeting on-premises deployments, with particular exposure among professional services firms still running legacy infrastructure. The second story details a misconfigured phishing operation that exposed 218 confirmed victims across twelve countries using Adversary-in-the-Middle techniques that bypass standard multi-factor authentication, including OAuth Device Code Flow attacks against Microsoft 365 and Google Workspace users. Finally, a supply chain attack against the AsyncAPI generator repository saw an attacker exploit a misconfigured GitHub Actions workflow to publish five malicious npm packages containing the Miasma botnet loader, which executes at import time without user interaction. The briefing emphasises that none of these attacks relied on novel techniques or nation-state resources, but succeeded through known vulnerabilities, unpatched systems, and insufficient authentication controls.

• Introduction Mauven opens the 15 July 2026 briefing, noting three stories involving confirmed victims and active exploitation, all stemming from known weaknesses rather than novel attack methods.
• SharePoint Server: Three CVEs, Active Exploitation, Patch Now CISA has added three Microsoft SharePoint Server vulnerabilities to its Known Exploited Vulnerabilities catalogue following confirmed active exploitation. The flaws affect on-premises deployments, not SharePoint Online. UK professional services firms, legal practices, and accountancy firms running legacy on-premises infrastructure face elevated risk. Mauven emphasises that KEV listing represents a late warning, not an early one, and calls for immediate patching and documented remediation.
• Call to Action Mauven encourages listeners to follow the show and share it with colleagues who would benefit from daily threat intelligence briefings.
• AiTM Phishing: Three Operators Exposed, 218 Confirmed Victims Lexfo researchers discovered a misconfigured Python HTTP server that exposed the infrastructure of three phishing operators, including one with 218 confirmed victims using OAuth Device Code Flow attacks and another operating an Adversary-in-the-Middle platform since 2018. AiTM attacks bypass standard multi-factor authentication by intercepting authenticated session tokens. Mauven explains why phishing-resistant MFA such as FIDO2 is necessary and provides specific guidance on OAuth Device Code Flow recognition and conditional access policy review.
• AsyncAPI npm Supply Chain: Poisoned Packages, Botnet Loader An attacker exploited a misconfigured GitHub Actions workflow in the AsyncAPI generator repository to exfiltrate a privileged access token, then published five malicious npm packages containing the Miasma botnet loader. The malicious code executes at import time without user interaction. Mauven advises organisations to audit AsyncAPI-related dependencies, review build logs from 14 July, and verify whether technology partners have assessed their exposure.
• Also Worth Noting The NCSC has announced that certified Cyber Advisors are offering free thirty-minute consultations for small businesses. Microsoft has halted Patch Tuesday updates for some Dell devices following reports of shutdowns and overheating.
• Closing Remarks Mauven concludes by noting that all three stories involve exploitation of known weaknesses through patience and known techniques, rather than exotic capabilities. The briefing emphasises checking on-premises SharePoint deployments and treating patching as an urgent priority.

Two active phishing kits, Jalisco and OmegaLord, are defeating multi-factor authentication on Microsoft 365 accounts through adversary-in-the-middle proxying and device code abuse. At the same time, documented research shows a jailbroken AI model built a fully functional command-and-control server in six minutes with minimal human input. For UK SMBs relying on MFA as their primary Microsoft 365 defence, these developments demand immediate action. Mauven examines how commoditised MFA bypass techniques work, why they matter disproportionately to UK professional services firms, and what controls to deploy now before Microsoft’s passkeys rollout in September. Also covered: critical SAP patches, actively exploited Joomla vulnerabilities, and practical steps to take this week. This episode makes clear that MFA alone is no longer sufficient, and the window to implement additional controls is closing as attack tools become cheaper and easier to deploy.

• Introduction Mauven introduces two critical developments: active phishing kits defeating Microsoft 365 MFA and AI-assisted attack infrastructure built in minutes. These trends signal a fundamental shift for UK businesses relying on MFA as primary defence.
• Jalisco and OmegaLord: When MFA Is No Longer the Answer Detailed examination of two operational phishing kits using adversary-in-the-middle proxying and device code abuse to defeat MFA on Microsoft 365. Explains why UK professional services firms are disproportionately exposed and outlines immediate mitigations including Conditional Access policies, FIDO2 keys, and token lifetime controls.
• Call to Action Mauven asks listeners to follow the show and share it with anyone relying solely on MFA for Microsoft 365 protection.
• AI Is Doing Ninety Per Cent of the Work Now Analysis of documented research showing a jailbroken Gemini model building a functional command-and-control server in six minutes. Discusses implications for UK SMBs as attack infrastructure becomes trivially easy to deploy at scale.
• Briefly Noted: SAP and Joomla SAP’s July 2026 patch addresses sixteen vulnerabilities including three critical flaws. Actively exploited Joomla extension vulnerabilities with CVSS 10.0 scores threaten UK SMB websites, particularly older professional services and hospitality sites.
• What to Do Today Four prioritised actions: verify Microsoft 365 Conditional Access configuration, patch Joomla extensions, review SAP July patches, and brief staff on device code authentication requests. Emphasises urgency of the MFA bypass issue.
• Outro Mauven summarises that MFA alone is insufficient for Microsoft 365 and that Conditional Access policies and phishing-resistant authentication are now baseline requirements.

This briefing examines three concurrent threats that share a common vulnerability: neglected infrastructure. The NCSC and eight international partners issued a joint advisory on Russian state actors (FSB-linked Static Tundra and Berserk Bear) exploiting poorly configured network edge devices to establish persistent access in critical infrastructure. The same techniques work on any misconfigured router, including those deployed in UK SMEs. Progress Software ordered an emergency shutdown of ShareFile on-premises storage zone servers without disclosing technical details, recalling the MOVEit compromise of 2023. Finally, Stormshield documented a phishing campaign impersonating DocuSign to install legitimate Remote Monitoring and Management tools (specifically Atera) as attacker infrastructure. Across all three incidents, the entry point is not sophisticated exploitation but basic configuration oversights: unchanged default credentials, unpatched firmware, unverified document signing workflows. UK small businesses using managed service providers, file transfer systems, or document signing tools face immediate exposure if they have not recently audited which remote access tools are authorised, verified router configurations, or trained staff to validate DocuSign notifications through the portal rather than email links.

• Introduction Mauven introduces three apparently unrelated threats that share a single operating principle: attackers exploiting unlocked doors rather than breaking through reinforced ones.
• Russian State Actors Targeting Network Edge Devices A nine-country joint advisory warns of FSB-linked actors exploiting misconfigured routers for persistent access. The technique works on any poorly configured device, not just critical infrastructure. UK SMEs must verify that default credentials are changed, remote management interfaces are disabled, and firmware is current.
• Call to Action Listeners are encouraged to follow the show and share it with others who need threat intelligence.
• Progress ShareFile Emergency Shutdown Progress Software ordered an emergency shutdown of ShareFile on-premises storage zone servers without disclosing technical details. Given Progress’s MOVEit breach history, UK SMEs using ShareFile must immediately verify whether they are affected and document what data transits through the platform.
• DocuSign Impersonation and RMM Tool Abuse Stormshield documented a phishing campaign impersonating DocuSign to install legitimate RMM tools (Atera) as attacker infrastructure. Because the payload is legitimate software, endpoint detection often fails to flag it. UK SMEs must train staff to verify DocuSign notifications through the portal, maintain an authorised RMM tool list, and treat any DocuSign prompt requesting software installation as malicious.
• Conclusion The three threats share a common vulnerability: organisations have not recently audited their own infrastructure. The action item for UK SMEs is to verify router configurations, file transfer system deployments, and authorised RMM tools this week, not next quarter.

A delayed patch for the RoguePlanet zero-day in Windows Defender has finally arrived, but working exploit code was publicly available for weeks before Microsoft closed the vulnerability. Mauven examines what that exposure window means for UK SMBs and why confirming patch deployment today is not optional. The Vidar infostealer campaign has quietly evolved beyond phishing emails into developer toolchains, with malicious Go modules staged across more than two hundred GitHub repositories designed to appear credible and actively maintained. Socket’s Operation Muck and Load research reveals how attackers are using commit farming and typosquatting to compromise software supply chains, particularly targeting payment SDK names. Finally, the NCSC has published guidance on Cyber Essentials Pathways, an alternate route to Cyber Essentials Plus certification that may reduce friction for smaller organisations pursuing verified assessment. Mauven explores what this policy shift signals about the growing expectation for Plus-level certification in public sector contracts and supply chain assurance. Three practical actions close the episode: verify the RoguePlanet patch has been applied, implement dependency verification for developers pulling open-source packages, and review the NCSC pathways guidance if you hold basic Cyber Essentials certification.

• Introduction Mauven previews three stories: a delayed zero-day patch, an infostealer campaign migrating into developer toolchains, and an underreported NCSC policy update with practical implications for UK small businesses.
• RoguePlanet Zero-Day Patched, Weeks Late Microsoft has patched the RoguePlanet zero-day in Windows Defender, but exploit code was publicly available for weeks before the fix arrived. Mauven explains the exposure risk, emphasises the urgency of confirming patch deployment, and advises reviewing any anomalous Defender behaviour during the vulnerability window.
• Mid-Episode CTA Mauven encourages listeners to follow the show and share Threat Analysis with colleagues who need daily UK threat intelligence briefings.
• Vidar Infostealer Moves Into Developer Supply Chains The Vidar infostealer campaign has evolved from phishing emails to compromising developer toolchains. Socket’s Operation Muck and Load research identified malicious Go modules staged across 222 GitHub repositories using commit farming to appear credible. Seventeen typosquatted packages targeting payment SDKs were published on 7 July. Mauven details practical verification steps for developers pulling open-source dependencies.
• NCSC Cyber Essentials Pathways The NCSC has published guidance on Cyber Essentials Pathways, an alternate route to Cyber Essentials Plus certification. Mauven contextualises the policy update, explains why Plus certification is increasingly required for public sector contracts and supply chain assurance, and advises organisations holding basic certification to review the new pathways guidance.
• Closing Actions and Outro Mauven summarises three priority actions: confirm the RoguePlanet patch has been applied, brief developers on dependency verification, and read the NCSC Cyber Essentials Pathways blog. Closing remarks reinforce the importance of understanding vulnerability windows and consistent threat awareness.

Ubiquiti has released security updates addressing seven critical vulnerabilities in UniFi OS, including one rated CVSS 10.0 that permits unauthenticated remote code execution. The widespread deployment of UniFi hardware in UK small business networks makes this a priority patching event. Separately, CISA has added an Adobe ColdFusion vulnerability to its Known Exploited Vulnerabilities catalogue, issuing an emergency patch deadline for US federal agencies after confirming active exploitation in the wild. ColdFusion remains widely deployed in UK professional services, legal and accountancy firms, and public sector environments, often in legacy web applications where platform visibility is poor. Finally, an ongoing phishing campaign delivering AsyncRAT and Remcos trojans continues to target finance, procurement, and operations staff using macro-enabled Excel attachments and fileless execution techniques. Mauven MacLeod provides specific guidance on how to verify patching status with IT providers, configure email filtering to block macro-enabled attachments, and enforce Office macro policy across business environments.

• Introduction Mauven opens the eighth of July briefing with a direct question about firmware version awareness, highlighting seven critical Ubiquiti UniFi OS vulnerabilities including one rated CVSS 10.0, a CISA emergency patch order for Adobe ColdFusion, and an ongoing phishing campaign targeting finance and procurement staff.
• Ubiquiti UniFi OS: Seven Critical Flaws, One at Maximum Severity Seven critical vulnerabilities in Ubiquiti UniFi OS have been disclosed, including a CVSS 10.0 command injection flaw permitting unauthenticated remote code execution. Given the widespread deployment of UniFi hardware in UK SMB networks and typically flat network architectures, successful exploitation provides attackers with perimeter-level access. Mauven advises requesting written confirmation of firmware updates from IT providers or checking firmware versions directly if self-managed.
• Call to Action Mauven encourages listeners to follow the show and share the episode with others who may have unpatched Ubiquiti infrastructure.
• Adobe ColdFusion: Actively Exploited, CISA Emergency Patch Deadline CISA has added a maximum-severity Adobe ColdFusion vulnerability to its Known Exploited Vulnerabilities catalogue, issuing an emergency patch deadline for US federal agencies by the end of the week. The flaw permits remote code execution and is confirmed exploited in the wild. ColdFusion remains widely deployed in UK professional services, legal, accountancy, and public sector environments, often in legacy web applications with poor platform visibility. Mauven recommends requesting written confirmation of patching from hosting providers and suppliers.
• On the Radar: AsyncRAT and Remcos Phishing Campaign An ongoing phishing campaign delivers AsyncRAT and Remcos remote access trojans via macro-enabled Excel attachments, using fileless execution techniques including steganography to evade signature-based detection. The campaign specifically targets finance, procurement, and operations staff who routinely receive Excel files from external parties. Mauven recommends disabling macro execution by default, deploying Attack Surface Reduction rules, configuring email gateways to quarantine macro-enabled files, and briefing staff in targeted functions.
• Closing Summary Mauven summarises three actionable items: obtain written confirmation of UniFi firmware updates, verify ColdFusion patching status with suppliers, and enforce Office macro policy with appropriate email filtering. None require significant budget, only deliberate follow-through.

This episode examines three active threat vectors affecting UK businesses in July 2026. First, a sophisticated Microsoft Teams impersonation campaign documented by Unit 42, in which attackers pose as IT helpdesk staff to deploy EtherRAT remote access trojans without requiring any technical vulnerability. Second, a global phishing operation delivering AsyncRAT and Remcos through multi-stage infection chains that use steganography and fileless execution to evade detection, targeting finance, HR, and procurement functions. Third, the UK government’s new voluntary cyber pledge, signed by sixty organisations including two currently managing recovery from significant recent breaches. The episode also covers UAT-7810’s operational relay box networks and the NCSC’s Cyber Shield initiative. Practical mitigations include restricting Teams external access, blocking Office macros by default, implementing helpdesk verification processes, and ensuring endpoint protection uses behavioural detection rather than signature matching alone. Each recommendation is actionable within the current week and addresses documented attack patterns actively being exploited against UK small and medium businesses.

• Introduction Overview of three stories: two active threats requiring immediate attention and one piece of UK government policy that merits closer examination beyond the press release.
• Teams Helpdesk Scam: EtherRAT Unit 42 research documenting attackers impersonating IT helpdesk on Microsoft Teams to deploy EtherRAT. The attack requires no technical vulnerability, only a helpful employee. Covers Teams external access configuration, verification processes, and remote access tool auditing.
• Call to Action Reminder to follow the show and share with colleagues who would benefit from daily threat intelligence.
• Multi-Stage Phishing: AsyncRAT and Remcos SpiderLabs research on global phishing delivering AsyncRAT and Remcos through Excel attachments, HTA scripts, PowerShell, and steganography-concealed payloads.

Today’s briefing covers two active threats facing UK small businesses. First, CVE-2026-48282, a maximum-severity vulnerability in Adobe ColdFusion confirmed to be under active exploitation by the Canadian Centre for Cyber Security and verified by BleepingComputer. The flaw permits unauthenticated remote code execution with a CVSS score of 10.0, affecting legacy installations across SMB websites, internal applications, and shared hosting environments managed by MSPs. Second, a criminal group designated CL-CRI-1147 and tracked as Pink is conducting voice phishing campaigns that impersonate IT helpdesks to extract credentials and bypass multi-factor authentication. Once inside, the group exfiltrates data from SharePoint and OneDrive, then issues a seventy-two-hour ransom demand. The tactic closely mirrors operations by UNC3753, documented by Google Cloud Threat Intelligence. Both threats exploit different attack surfaces but share a common trait: neither discriminates by organisation size. Mauven provides specific procedural guidance for patching, MSP coordination, staff briefings on vishing, and audit log monitoring to detect bulk data downloads before ransom demands arrive.

• Introduction Mauven introduces two current threats facing UK small businesses: an actively exploited Adobe ColdFusion vulnerability and a criminal vishing operation. Both target SMBs without discrimination based on size or sophistication.
• Adobe ColdFusion CVE-2026-48282: Patch It Today, Not This Week Analysis of CVE-2026-48282, a maximum-severity vulnerability in Adobe ColdFusion confirmed under active exploitation. Covers CVSS 10.0 scoring, unauthenticated remote code execution, exposure through legacy systems and MSP-managed environments, and immediate patching requirements.
• Call to Action Brief audience prompt to follow the show and share the briefing with colleagues who need current threat intelligence.
• Pink (CL-CRI-1147): When the Threat Just Calls You Up Examination of the Pink criminal group’s vishing operation that impersonates IT helpdesks to extract credentials and bypass MFA. Details the exfiltration timeline, procedural defences, staff briefing requirements, and technical monitoring for SharePoint and OneDrive bulk downloads.
• The Pattern Worth Noting Structural analysis connecting the Adobe vulnerability, vishing campaigns, and emerging ClickFix malware ecosystem. All three exploit different attack surfaces but converge on the same principle: automated and human-driven threats do not filter targets by organisation size.
• Closing Summary of two actionable steps: verify and patch ColdFusion installations immediately, and brief staff on the vishing rule that IT will never request credentials or MFA approval by phone.

This briefing examines three significant threats to UK small and medium businesses in July 2026. First, Cisco Talos’s analysis of ARToken, a phishing-as-a-service platform exploiting Microsoft 365 device code authentication flows to bypass multi-factor authentication. The technique, productised for affiliate use, requires immediate Conditional Access policy review. Second, Blackpoint Cyber’s documentation of Avalon, a multi-stage ransomware framework using spoofed legal documents, Proton Drive hosting, and memory-only execution to evade detection. Third, the NetNut botnet takedown by Google and the FBI, involving two million compromised residential devices used as proxy infrastructure. The operational implications extend beyond the headline: unpatched IoT devices and routers continue to provide access via vulnerabilities from 2017 and 2018. Each attack is designed to appear normal within legitimate business operations. The briefing provides three concrete actions: restrict device code authentication in Entra ID, establish verification procedures for password-protected archives, and audit firmware on internet-facing devices. These measures address the gap between assumed and actual security control effectiveness in small business environments.

• Introduction Mauven introduces three threat items for 3rd July 2026, prioritised by risk to UK SMBs. Two are active attack campaigns with direct exposure, one is a law enforcement action with under-reported operational implications.
• ARToken M365 Phishing Platform Analysis of ARToken, a phishing-as-a-service platform exploiting Microsoft device code authentication flows. The technique bypasses MFA by abusing legitimate authentication processes. Direct mitigation requires restricting device code flows through Conditional Access policies in Entra ID.
• Call to Action Listener engagement prompt encouraging follows and sharing.
• Avalon Ransomware Framework Blackpoint Cyber’s analysis of Avalon, a multi-stage attack framework using spoofed legal documents hosted on Proton Drive, password-protected ISO archives, and memory-only execution. Targets professional services with plausible social engineering. Requires staff training, behavioural endpoint detection, and ISO mounting restrictions.
• The NetNut Botnet Takedown Google and FBI action against NetNut residential proxy botnet involving two million compromised devices. Discusses how compromised devices provide cover for credential stuffing and fraud, and notes active propagation of similar botnets via vulnerabilities from 2017 and 2018. Emphasises firmware update and credential hygiene on internet-facing devices.
• Broader Pattern Note All three threats share a common characteristic: they are designed to appear normal within legitimate business operations. The security gap lies between assumed and actual control effectiveness, closed through visibility rather than additional tools.
• Outro Closing summary with practical question for IT providers regarding Conditional Access policies. Sign-off and production credit.

The Gentlemen ransomware group has emerged as a top-ten global threat actor by deploying zero-day driver exploits to disable endpoint security tools before launching encryption attacks. Using a vulnerable Kontron driver and the Bring Your Own Vulnerable Driver technique, the group neutralises detection systems silently, often gaining hours of undetected access through compromised VPN and firewall appliances. Meanwhile, the ARToken phishing-as-a-service platform automates Microsoft 365 account takeover through device code phishing and Primary Refresh Token persistence. Standard multi-factor authentication does not prevent these attacks, as the OAuth authentication flows are legitimate. The platform includes automated email and SharePoint exfiltration, plus integrated business email compromise tooling that industrialises payment redirection fraud. UK small businesses using Microsoft 365 face direct exposure, particularly in professional services, accountancy, and financial sectors where client data and payment processes rely on email systems. The NCSC has published guidance on restricting device code flow and monitoring for these attacks, yet implementation remains inconsistent even in critical national infrastructure environments.

• Introduction Overview of two urgent threat developments: a ransomware group defeating endpoint security and an automated Microsoft 365 phishing platform bypassing multi-factor authentication.
• The Gentlemen Ransomware Group and Zero-Day Driver Exploits Analysis of The Gentlemen’s rise to top-ten threat status through Bring Your Own Vulnerable Driver techniques, their use of a Kontron driver zero-day to disable endpoint protection, and their systematic approach to network reconnaissance and ransomware deployment.
• Call to Action Encouragement to share the briefing and subscribe for daily updates.
• ARToken: Automated Microsoft 365 Account Takeover Detailed examination of the ARToken phishing-as-a-service platform, its device code phishing methodology, Primary Refresh Token persistence, automated data exfiltration, and integrated business email compromise workflows that bypass standard MFA.
• NCSC Penetration Testing Findings Brief discussion of persistent security gaps identified in critical national infrastructure, including default credentials, insufficient segmentation, and poor patch management.
• Closing Recommendations Summary of immediate actions: enable tamper protection, verify monitoring procedures, restrict device code flow in Microsoft 365, and implement out-of-band payment verification.

Two critical threats demand immediate attention from UK small businesses today. First, the BlueHammer vulnerability in Microsoft Defender has transitioned from targeted zero-day attacks to commodity ransomware operations, a shift that dramatically expands the pool of threat actors capable of exploiting it. CISA’s addition of BlueHammer to its Known Exploited Vulnerabilities catalogue confirms active exploitation in the wild, with the flaw enabling attackers to escalate privileges to SYSTEM level and deploy ransomware across entire networks. Second, Blackpoint Cyber has documented an active intrusion chain exploiting CVE-2026-48558, an authentication bypass in SimpleHelp remote monitoring and management software. This attack vector is particularly concerning because it targets the tools IT providers use to manage client systems, turning the trust relationship between businesses and their managed service providers into an attack surface. The operational implication is clear: attackers are systematically exploiting the privileged access that IT management tools provide, bypassing direct targeting in favour of supply chain compromise. Patches exist for both vulnerabilities. The gap between availability and deployment is where ransomware operators operate. UK SMBs should contact their IT providers today to confirm patching status and ask specific questions about RMM tool security. This briefing provides actionable guidance on exactly what to ask and why it matters.

• Introduction Mauven introduces today’s two threat stories: the BlueHammer vulnerability in Windows Defender crossing into commodity ransomware operations, and an attack targeting remote management tools used by IT providers.
• BlueHammer: From Zero-Day to Ransomware Commodity Analysis of CISA’s KEV addition for BlueHammer, a privilege escalation flaw in Microsoft Defender now exploited in commodity ransomware operations. Covers the transition from targeted attacks to volume-based campaigns, the operational playbook of ransomware-as-a-service groups, and the practical patching actions UK SMBs must take immediately.
• CTA Brief call to action encouraging listeners to follow the show and share it with business owners and operations managers who need actionable threat intelligence.
• SimpleHelp RMM: The Attack That Comes Through Your IT Provider Detailed examination of CVE-2026-48558, an authentication bypass in SimpleHelp remote monitoring and management software. Explains how attackers exploit RMM tools to gain technician-level access to managed client systems, the malware deployed (TaskWeaver and Djinn Stealer), and the supply chain risk this represents for UK SMBs.
• What UK SMBs Should Do Today Direct, actionable guidance for UK small businesses: specific questions to ask IT providers about BlueHammer patching, SimpleHelp vulnerability status, RMM access log reviews, and incident disclosure processes.
• Outro Closing summary emphasising the gap between patch availability and deployment, urging businesses to actively verify patching status with their IT providers rather than assume it has been handled.

Oracle E-Business Suite vulnerability CVE-2026-46817 is under active exploitation, with confirmed activity from threat intelligence firm Defused. Nissan’s recent breach of its Oracle PeopleSoft instance underscores the broader risk to Oracle’s enterprise portfolio. UK small businesses face exposure through supply chain relationships with payroll bureaus, accountancy firms, and manufacturers running Oracle systems. Meanwhile, newly documented threat actor DriveSurge operates a pay-per-install initial access broker model, compromising legitimate websites to deliver malware through fake browser updates and ClickFix social engineering. The campaign bypasses email security controls entirely, infecting users through normal web browsing. Additional concerns include active exploitation of Langflow (CVE-2026-55255) and the Miasma Mini Shai-Hulud supply chain campaign now targeting Backstage npm packages. Today’s briefing provides specific, actionable steps: verify Oracle patch status with suppliers, implement web filtering against zTDS infrastructure, brief staff on fake browser update prompts, and audit dependencies in development pipelines. These are email-and-call actions, not budget-heavy projects.

• Introduction Mauven opens with two active threat stories: exploitation of Oracle E-Business Suite and a drive-by attack campaign bypassing email controls through compromised websites. Both pose immediate risks to UK small businesses through supply chain and web browsing vectors.
• Oracle EBS Active Exploitation CVE-2026-46817 in Oracle E-Business Suite is under confirmed exploitation.
