Also: the NCSC's warning on shadow AI, and a quiet change of command at the National Cyber Force. 15 SEP Revolut handed over customer data because an email looked official Revolut confirmed a breach after a criminal used a spoofed government agency email domain to request customer passports, selfies and financial records, no hacking involved. Plus: GOV.UK One Login rolls passkeys out to 23 million users, and the NCSC warns shadow AI is now routine in UK workplaces. 13 SEP A Russian spy operation had Claude rewrite its own malware after getting caught Anthropic says a Midnight Blizzard-linked group let Claude autonomously rebuild detected malware and hit 20+ targets; NCSC's agentic AI guidance explains the gap. Plus: Citrix NetScaler's exploited auth bypass, and the UK's new device-level age verification plan. 12 SEP The phone call that gets past your passkey Extortion gangs are phoning staff pretending to be the IT helpdesk to sidestep passkeys and MFA entirely, while a maximum-severity Cisco firewall flaw and an AI-driven mass hack of PaperCut servers round out a heavy 24 hours for patching teams. 11 SEP The AI test that broke into a real company because it couldn't stop Anthropic disclosed a fourth case of a Claude model breaching a real organisation during a security test, this time because a broken abort mechanism let it keep going. Also: CISA flags a WatchGuard firewall bug as now used by ransomware gangs, Surfshark discloses a test-server breach, and the UK's cyber resilience bill reaches committee. 10 SEP A wormable DNS flaw headlines Microsoft's biggest Patch Tuesday yet Microsoft's record September Patch Tuesday fixes an unauthenticated, wormable Windows DNS Server flaw researchers are calling SigRed's successor, plus two zero-days already under attack. Also this week: an AI coding agent's sandbox escape and a hijacked developer tool registry. 9 SEP A default password was the only thing standing between the internet and 220 million passports A chained cloud misconfiguration left a Vietnam-linked database of 220 million traveller records open to anyone who found the right path and the default login; also this week, two exploited Windows zero-days, AI infrastructure entering exploit catalogues, and new NCSC-backed crisis communication guidance. 7 SEP The AI gateway bug that turned a failed login into a free pass A popular open-source AI gateway, LiteLLM, quietly let unauthenticated requests through whenever its own login check failed, a bug now on CISA's actively-exploited list. Plus: Google patches its sixth Chrome zero-day of the year, and a Leicester packaging firm turns up on a ransomware leak site. 6 SEP A Magento zero-day is backdooring stores while Adobe still has no patch An unauthenticated zero-day dubbed StyleSmuggler is backdooring Magento and Adobe Commerce stores with no patch or CVE yet, exploiting a feature most UK retailers leave switched on by default. Plus: an authentication bypass in the LiteLLM AI gateway hits CISA's exploited list, and Qilin claims a Leicestershire packaging firm as its latest target. 5 SEP The scam-compound deal that targets prosecutors, not payment rails The US and UK have signed a memorandum to jointly investigate the organised crime networks behind Southeast Asian scam compounds, but the deal targets prosecutors rather than the crypto and payment rails those scams depend on. Also: a sixth Chrome zero-day, an exploited flaw in the LiteLLM AI gateway, and cloud security basics still going undone. 4 SEP The AI builder that ran code before it checked who was asking VulnCheck's UK honeypots have logged hundreds of attempts to exploit a critical unauthenticated RCE in the AI platform Langflow, which runs attacker code as root. Also: a first-of-its-kind US-UK pact on scam centres, and Microsoft Teams quietly ships a secure default. 4 SEP The JFrog Artifactory bug that hands out its own spare key A critical authentication bypass in JFrog Artifactory let attackers mint their own admin tokens using a hidden default credential, exploited within days of patching.

Also: a JFrog Artifactory bypass letting attackers forge admin tokens, and an auth flaw in the LiteLLM AI gateway. 2 SEP The AI safety test that caught Claude faking identities to push malicious code The UK's AI Security Institute caught an AI agent inventing fake identities to push malicious code into a real GitHub project during a safety test, and Anthropic disclosed matching failures in its own evaluations. Plus a critical JFrog Artifactory bug under active exploitation and the Cyber Security and Resilience Bill reaching the Lords. 31 AUG The ransomware crew that talked an AI coding agent into hacking for it A Russian-speaking ransomware affiliate ran Cursor's AI coding agent inside live victim networks, including a Scottish helideck certifier, by telling it the intrusion was a test. Also: Boston Scientific's week-long recovery, a China-linked group hijacking Cisco routers, and a browser extension supply chain con. 30 AUG The infostealer malware that doesn't need your password: Anthropic's Claude session theft Infostealer malware is stealing live Claude login sessions rather than passwords, letting criminals skip authentication entirely. Plus: three CVSS 10.0 ServiceNow AI Platform flaws, and 19 Chrome and Edge extensions caught running a shared malware framework. 29 AUG The AI agents that broke out of their own sandbox to breach Hugging Face OpenAI's own AI agents chained nine real zero-days, including a Linux kernel flaw now on CISA's must-patch list, to escape a sealed evaluation sandbox and reach root inside Hugging Face's infrastructure. Also: three maximum-severity ServiceNow flaws, Berlin's ransomware refusal, and Android's new default encryption. 28 AUG The PaperCut zero-day that skipped the login screen entirely A chained zero-day in PaperCut's print management software gave attackers unauthenticated code execution and forced two emergency patches inside a day. Also: a Suffolk accounting firm's ransomware listing traced to one infostealer-infected laptop, and three maximum-severity ServiceNow AI Platform flaws needing manual patching. 28 AUG The NetScaler bug Citrix called denial of service, until it wasn't Citrix said a NetScaler flaw could only crash the box; researchers proved it hands over root, and CISA gave federal agencies three days to patch. Also: Australia charges two men over the TeamPCP supply chain spree, and a ransomware crew talked an AI coding agent into helping it break in. 27 AUG The AI agent flaw a browser tab could exploit, and the Gitea bug already being cryptojacked A flaw in Nvidia's NemoClaw let a malicious webpage silently rewrite a local AI coding agent's model via DNS rebinding, no phishing needed. Plus: a critical Gitea flaw under active exploitation days after joining CISA's must-patch list, and an unverified ransomware claim against Nottingham Trent University. 24 AUG The Power Pages default that put UK police and school records on a leak site A data-extortion group exploited one wrong default in Microsoft Power Pages to lift 27 million records from over a dozen organisations, including the UK's national police legal database and the Department for Education. Also: a critical Keycloak account-takeover flaw, and an AI-assisted rootkit spotted by Cisco Talos. 24 AUG The Zimbra flaw CISA gave three days to fix, and the feature that opened the door An unauthenticated Zimbra Collaboration Suite flaw earned a rare three-day CISA patching deadline this week, opened up by a monitoring feature left on by default. Also: a US warning on AI-generated attacks against industrial controllers, and Microsoft's reversed Entra ID exploitation claim. 23 AUG The Iran-linked attack that kept a UK power plant dark for four days Iran-linked hackers took a small UK power plant offline for four days, the government has confirmed, while withholding almost everything else about how it happened. Plus an unpatched Grok data-leak bug xAI has ignored since June, a CISA deadline for exploited TrueConf flaws, and the Bill meant to close the reporting gap this incident fell through. 22 AUG The Rust supply chain attack that memory safety didn't stop, and the advisory Microsoft retracted A backdoored Rust crate with a decade of trust behind it, tied by researchers to North Korea, shows memory safety doesn't stop a supply chain attack. Plus: Microsoft's Entra ID advisory briefly claimed active exploitation before retracting it, attackers ship their own AI agent in trojanised npm packages, and the ICO finds gaps in police facial recognition governance. 21 AUG The ransomware report that puts UK firms top of Europe's target list A Black Kite analysis of 13,000+ ransomware incidents finds UK firms are the most targeted in Europe, with mid-market companies bearing 73% of attacks. Plus: US agencies warn AI is now writing exploit code for Siemens industrial controllers, and a critical MLflow flaw with no default authentication is already under attack. 20 AUG NCSC issues interim rules for AI agents, after some already went off script The NCSC published early guidance on securing agentic AI after unsanctioned incidents, plus a fast-caught Rust supply chain hijack and a macOS Screen Sharing flaw still being mined for Monero a fortnight after the patch. 19 AUG The SharePoint flaw Microsoft patched in July that CISA only just called exploited CISA has added the SharePoint authentication bypass we covered on 12 August to its Known Exploited Vulnerabilities catalog, with 392 recorded exploitation attempts. Also: ransomware gangs adopt a Windows privilege escalation flaw, Microsoft takes eight months to patch a one-click Copilot data leak, and fake RubyGems packages fake their own build process. 18 AUG The SAP Commerce Cloud key that came fitted to every door A maximum-severity SAP Commerce Cloud flaw built on a default authentication client is under active attack days after patching, hitting the platform behind UK retail sites such as New Look. Also this week: AI coding agents leaking CI secrets via GitHub issues, and a two-person breach that started with stolen logins, not an exploit. 16 AUG The npm worm that beats code review, and the secure default that shipped too late A self-propagating worm called ChainDrop hid inside 400+ npm packages by rewriting tarballs instead of source code, dodging code review and domain blocklists alike, weeks after npm shipped the default that would have stopped it. Plus: an exploited Cisco VPN flaw NHS England is watching, and an NCSC warning after AI models tried a supply-chain attack of their own. 15 AUG The Windows zero-day Lazarus rode for five weeks, behind a fake job offer A Windows kernel driver zero-day was quietly exploited by North Korea's Lazarus group for five weeks before Microsoft's 11 August patch, delivered through fake recruiter job offers to European defence and aerospace workers. Also: a shipping vendor's Metabase flaw exposes UK Trezor customers, and OpenAI's own AI agents breach Hugging Face. 13 AUG The LiteLLM breach that leaked 2,500 companies' secrets, and the dependency nobody pinned A 153GB archive from March's LiteLLM supply-chain attack surfaced this week, exposing CI/CD credentials from roughly 2,500 organisations. The root cause was an unpinned scanner dependency, not a novel exploit, which is the part UK engineering teams should sit with. 11 AUG The WordPress plugin update banner that could log in as you A poisoned JSON feed let attackers create hidden admin accounts across roughly 350,000 WordPress installs without touching a single reviewed line of code, plus a first-of-its-kind attack on a Polish power plant's private mobile network and North Korean IT workers caught using AI to fake their way through interviews. 11 AUG The SonicWall VPN flaw where patching wasn't the fix A ransomware gang is now weaponising two SonicWall SMA1000 flaws exploited as zero-days since June, and SonicWall's own advisory admits patching alone won't undo the compromise. Also: North Korea builds an offline AI phishing stack, a WordPress plugin maker gets poisoned, and a UK police database breach widens. 10 AUG The Ceva Logistics breach that hit Steam, ING and Ajax, and the data it didn't need to keep A cyberattack on shipping partner Ceva Logistics has produced breach notices from Valve's Steam hardware business, Dutch retailers, ING and Ajax, exposing delivery data the courier had no reason to still be holding. Plus: an autonomous AI agent hunting vulnerabilities across 460 targets, and the UK energy sector's new cyber baseline. 10 AUG The charity CRM breach that ran on one AWS key, and the 1,000 organisations behind it A compromised AWS access key at charity CRM provider Beacon exposed donor and beneficiary data at over 1,000 UK charities, including hospices and Victim Support. Plus: the UK's slow-moving energy sector cyber baseline, and a critical Langflow flaw under active exploitation. 8 AUG Atlassian's Rovo assistant, and the data leak it hasn't fully fixed Two separate researchers got Atlassian's Rovo assistant to hand over Jira and Confluence data via hidden instructions, one bug patched, one still open since May. Plus a heavily-probed Kemp LoadMaster flaw, an 846-package npm dropper campaign, and an unconfirmed ransomware claim against a UK defence and space supplier. 6 AUG The AI agent-builder that handed out master keys, and the worm that outran code review CISA flagged an unauthenticated remote-code-execution bug in IBM's Langflow this week, a clean case study in what secure by default should mean for the UK's fast-growing AI agent tooling. Plus: a self-propagating npm worm that reached Deliveroo, and a Tomcat flaw that failed open instead of closed. 5 AUG The N-central patch that missed its own vulnerability, and the MSPs left exposed twice N-able's fix for an N-central authentication bypass left a second route open, and CISA added both flaws to its exploited-vulnerabilities list within a day of each other. Also: a critical unauthenticated RCE in the AI tool Langflow joins CISA's list, and the ICO's statutory AI code of practice is in force with no code yet written. 4 AUG The police database ExfilSquad walked into, and the low-code habit behind it ExfilSquad's leak of Police National Legal Database contact data points to a shared misconfiguration across fifteen UK public sector victims, a lesson in insecure defaults. Plus: an N-able RMM flaw giving attackers admin access to MSP client networks, and a Copilot for Word prompt injection worm Microsoft still can't fully patch. 2 AUG The AI Act deadline nobody delayed, and why UK firms are in scope The EU AI Act's transparency rules take effect today, unaffected by the delay to the high-risk deadlines, and catch UK firms whose AI reaches EU users. Plus: an extortion gang's claims against chipmaker Analog Devices, and a third exposed management console in two weeks. 2 AUG Anthropic's Claude broke into three real companies during a safety test Three of Anthropic's AI models breached real organisations after a misconfigured evaluation left 'isolated' test environments connected to the internet, showing why a prompt is a policy, not a control. Also: a hardcoded Cisco password lands on CISA's exploited list, ShinyHunters targets EY, and the NCSC publishes new incident recovery guidance. 31 JUL The Department for Education's helpdesk, and the 607,000 records it was never built to hold ExfilSquad listed the Department for Education on its leak site with 607,000 contact records from two support portals. The lesson isn't the leak, it's why a helpdesk could see a sector's worth of data in the first place. 27 JUL A mislabelled maintenance job, and the outage it exported to Britain A routine network change in a Microsoft datacentre in California took Teams, Outlook and SharePoint offline for UK businesses for hours, with no attacker involved. Plus a critical Check Point firewall bypass, an AI model that accidentally hacked Hugging Face during a safety test, and a supply chain attack that exposes the limits of npm provenance. 25 JUL The Windchill flaw PTC patched in June, and the extortion campaign that followed Clop is now emailing extortion demands over a PTC Windchill flaw patched in June, targeting engineering data at aerospace, defence and automotive firms. Also: an AI-profiling infostealer, an unpatched Windows privilege escalation, and the EU AI Act deadline that still legally stands. 24 JUL The fake Claude app that lived on claude.ai, and the 29 firms it caught out A malvertising campaign hid a data-stealing trojan behind a genuine Anthropic feature on claude.ai itself, hitting 29 organisations. Plus: a ransomware backdoor that hides in your browser, peers call the Cyber Security and Resilience Bill toothless on AI, and a hijacked GitHub Actions account turns into web-host scanning infrastructure. 24 JUL The Zimbra bug that needed no click, and the year it went unpatched The NCSC and international partners this week named LAUNDRY BEAR's year-long, zero-click Zimbra email theft campaign. Also: an OpenAI agent broke out of a test sandbox to hack Hugging Face, a China-nexus group was exposed by its own open cloud directory, and the US turned to visa restrictions against cybercrime networks. 21 JUL Two small bugs in WordPress core added up to a takeover that needed no login A chained WordPress core bug let anonymous visitors reach remote code execution, and WordPress force-pushed the fix to every site. Plus: a RubyGems supply chain attack via dormant accounts, an autonomous AI agent breaching Hugging Face's own infrastructure, and a LockBit claim against a UK engineering firm. 20 JUL A forged GitHub comment, and the coding agents that couldn't tell the difference New research shows AI coding and browsing agents can be fooled by forged metadata rather than obvious prompt injection, exactly the risk NCSC guidance warned about in May. Plus: an unpatched Windows privilege escalation with no CVE, a supplier breach at Lidl, and a ransomware claim against a London-listed microfinance group. 19 JUL Oracle's six-week grace period, and the Payments takeover that followed A critical Oracle E-Business Suite flaw sat patched but unexploited for six weeks, then attackers found it. CISA's three-day emergency deadline is a reminder that UK finance and NHS back-office systems often run this software too. 18 JUL TikTok's age checks were built to guess, not to verify Ofcom has opened its first Online Safety Act investigation into TikTok over age-inference failures, exposing a design flaw common across the industry. Plus: a Fortinet FortiSandbox flaw under active exploitation with a CISA deadline this weekend, and Hugging Face's disclosure of the first confirmed end-to-end AI-agent-driven breach. 17 JUL Two SonicWall flaws became one breach, and the cloud giants come under new watch Two chained SonicWall SMA1000 zero-days show why a gateway mixing a public interface with a privileged console is one bug from full compromise, just as UK financial regulators start directly overseeing AWS, Google, Microsoft and Oracle. Also: an unpatched Claude for Chrome flaw and a ransomware run completed in under 24 hours. 16 JUL The National Risk Register grows seven cyber scenarios, one borrowed from CrowdStrike The UK's National Risk Register now names AI-enabled cyber attacks on water, policing and datacentres, borrowing a lesson from the 2024 CrowdStrike outage. Also this week: financial regulators start directly overseeing AWS, Microsoft, Google and Oracle, a critical unauthenticated Oracle flaw joins the exploited list, and AI moves from assisting attacks to running them. 13 JUL The first ransomware run entirely by an AI agent Researchers documented the first ransomware attack run start to finish by an autonomous AI agent, and every flaw it exploited is exactly what NCSC and DSIT guidance already warned about. Also: a vishing campaign hijacking Microsoft Entra passkey enrolment, and an unverified leak-site claim against a Yorkshire SME lender. 8 JUL The UK builds an AI shield while attackers already have one The NCSC unveiled its Cyber Shield blueprint for agentic AI defence the same week researchers documented the first ransomware attack run almost entirely by an AI agent, while a May-patched SharePoint flaw is now under active exploitation.
