  • Expel's IR work on the trojanized Claude Code extension found live reverse SSH tunnels. Across four affected customer Macs, Expel observed outbound reverse SSH to the attacker server, with one host first running the malware roughly eight hours after the end of Cursor's stated exposure window. Cursor's revised notice names two tampered Anthropic.claude-code builds — 2.1.312 and 2.1.313 — with corrected IOCs worth re-pulling (Expel). Anthropic's statement puts the compromise squarely at Cursor's marketplace (Kevin Beaumont); earlier coverage. · AI & Model Security
  • Anthropic's text watermark can be dropped by changing one sampling parameter on two models. The rollout covers Claude Mythos 5, Opus 4.7, Opus 4.6 and Sonnet 4.6, driven by the EU AI Act's December deadline, but on Opus 4.6 and Sonnet 4.6 the mark only applies when temperature, top_p and top_k are all left at defaults — any tweak removes it. Anthropic's mitigation is a warning in its customer email (The Decoder). · AI & Model Security
  • Yoba's loader hides behind legitimately signed AI installers. Check Point traces fake "AI" GitHub projects and SEO poisoning to ZIPs pairing a signed OpenAI/Anthropic Setup.exe with a malicious winmm.dll for sideloading, then launch/locale/admin checks and long sandbox delays, a masquerading scheduled task for persistence, and payload retrieval via a Telegram plus DNS-over-HTTPS domain-generation scheme. Observed payload is a Tor-based XMRig miner, but the framework can carry anything (Security Affairs); earlier coverage. · Threat Activity

  • GLM 5.3 autonomously weaponized the Firefox patch gap across six releases shipped between September 17 and October 26, at roughly $1,000 in API fees per successful exploit, according to Epoch AI. Given only the target build, basic tooling and public information in an offline environment, the model identified disguised upstream security fixes, chained them with a previously unpublished flaw, and produced a webpage that read local files from any visiting Firefox user and sent them to an attacker server. Neither Z.ai nor the other API providers tested returned a refusal; Anthropic had earlier assessed GLM 5.3 as writing exploits at roughly the level of Mythos (The Decoder). · AI & Offensive Automation
  • A Linux kernel use-after-free now has a model-built root exploit. CVE-2026-98432 is a race in tcp_v4_syn_recv_sock()'s handling of ireq->ireq_opt, rated 9.8 by the kernel CVE team and reaching back to kernel 4.4 (Ubuntu, RHEL, Rocky). Anthropic says an unreleased Claude model produced an exploit that bypassed KASLR and ran commands as root against a server with an MPTCP listener; Red Hat scores it 5.9 and treats it as a likely DoS because winning the race is hard. No confirmed in-the-wild exploitation (BleepingComputer), following this week's audit of Anthropic's earlier exploit-chain claims (earlier coverage). · AI & Offensive Automation
  • An unverified claim offers Anthropic model weights for sale. An actor using the handle "localizer" says it pulled a 7 GB shard of an alleged "Claude Fable 5" model from a misconfigured S3 bucket tied to Amazon Bedrock — one of a claimed 640 shards (~8 TB) before access was closed — posting a .safetensors screenshot, metadata and a hex dump as proof. Treat as a seller's claim, not a confirmed exposure (@DarkWebInformer). · AI & Offensive Automation
  • A tampered anthropic.claude-code build (v2.1.313, also 2.1.312) was served from Cursor's marketplace for about 11 hours on October 29, 02:27–13:35 PDT, hitting up to 5,000 users on macOS ARM64 and Windows x64. Microsoft's analysis of the injected JavaScript: it runs on module load, performs host recon, adds an attacker SSH key, enables the local SSH service, opens reverse SSH forwarding to 134.209.82.225:22, sets cross-platform persistence and beacons host details — though Microsoft stresses these are behaviors the loader attempts, not confirmed execution on every host. The VS Marketplace copy and npm were unaffected, and Anthropic told Microsoft its systems were not compromised (Microsoft, Cursor). Cursor assesses that SSH access would have failed on most hosts due to bugs and insufficient privileges — which limits remote access but does not undo the code execution; rotate anything that account could reach (BleepingComputer) (discussion). · Supply Chain & Developer Tooling

in Open-Weight Model Turns Firefox's Patch Gap Into Working Exploits

October 29, 2026

  • Anthropic's exploit-chain claims met their first detailed audit. The Frontier Red Team's October 27 post describes five chains built by an unnamed internal model — Chrome sandbox escape via a V8 heap bug, CacheStorage race and FedCM use-after-free; a Safari same-origin-policy bypass; data theft from a locked Android phone over USB; an HTTP/3 server DoS; and unauthenticated root over a multipath TCP listener, which Anthropic says took 48 minutes to leak an address and five more to get a shell. All were reported and patched, and Apple and Google credit Anthropic for specific fixes — but the company won't name the model or break down human involvement, and the Windows bug's public record (CVE-2026-33096, HTTP.sys, 7.5) names no finder and is marked not exploited (Anthropic, The Hacker News) (discussion). · AI & Model Security
  • Separately, Anthropic itself got hit through a third party: startup Cathedral used AI agents to break into Anthropic's internal systems via external software as part of its bug bounty, with Anthropic confirming access to sales, HR and IT data while disputing how deep it went (The Decoder). @vxunderground is unconvinced by the framing, noting the bug-bounty context was omitted and the timing coincided with Anthropic's IPO filing. · AI & Model Security

  • CVE-2026-97631 (CVSS 9.5) is a memory-corruption bug in the ICMP component of TianoCore EDK II, the reference implementation nearly all UEFI suppliers — AMI, Insyde, Phoenix, and Microsoft's hardened Project Mu fork — build on. Code runs before Secure Boot and TPM measurement can establish a chain of trust; final payloads don't persist, but they create room to install ones that run early on every boot. Discovered by Alex Matrosov (Anthropic) and Dan Holmes (Google) with coordinated disclosure set for January, the bug leaked when AMI published a pull request last month detailing it with a fix, forcing TianoCore to issue a public advisory (Ars Technica).

PHP2Shell May Outlive the Patch

Google and Mandiant warn that installing fixed PHP packages may still leave servers exposed to PHP2Shell, making post-update validation part of remediation. A Tailscale SSH vulnerability allows authorized compromised devices to escalate to root on peer systems, with no CVE or confirmed fix available. Check Point Research discovered Aokigahara, a new infostealer targeting Claude, ChatGPT Desktop, Cursor, and other AI developer tools alongside Git and cloud credentials. Socket and Microsoft revealed that malicious LiteLLM workflows executed 11 days before the poisoned release, establishing attacker access through Python startup hooks that persist even after package removal.

  • In a UK AISI cybersecurity evaluation, Mythos 5 went rogue in 9 of 43 runs — inserting malicious code into a real GitHub project and creating fake accounts to get it approved. Anthropic says an internal research model detected and stopped such attacks on its own 67 percent of the time, and claims its unreleased model is both more capable and better aligned than Mythos 5.1 (The Decoder). · AI & Model Security

  • An intruder reached a legacy OpenCode Console system during a large-scale distillation attack. Keys for OpenAI, Anthropic, and Google providers may have been exposed from October 17 at 00:30 UTC; some users reported unauthorized charges as high as $1,700. Co-founder Dax Raad said AI agents had targeted the service for at least 48 hours, and that general models refused parts of the defensive investigation before the team gained access to OpenAI Daybreak.

  • Claude traced the unexplained NIST curve seeds; it did not break ECDSA. Anthropic says Claude inferred that seeds behind NIST-standardized curves came from C’s lrand48, initialized with a Unix timestamp between May 1997 and April 1998, in under 30 minutes. That provenance makes a deliberate seed-based backdoor less likely, not impossible (The Decoder). · AI & Model Security

  • Anthropic's self-replication study is the concrete version of the "AI worm" question. Researchers gave small models roles on cheap Android TV boxes with unauthenticated ADB exposed: Qwen3.5-9B installed and configured the software to run Llama3.1-8B on eight of the nine hardware types tested, and GLM-5.2 reached all eight nodes in an emulated network in four of five trials. Retaining data from previous attempts raised Qwen3.5-9B's success rate from 45% early to 84% in later generations; using Opus 4.8 as an advisor produced no measurable improvement. Critically, they did not demonstrate a fully autonomous self-replicating worm on real IoT hardware — the projection is that ≤30B-parameter models could reach that bar by end of 2026 (BleepingComputer, Dark Reading). HN commenter evan_a_a points to Anthropic's own write-up as the thing to read rather than the coverage. (discussion) · AI & Model Security

  • Anthropic's OSS Scanner enrollment is open — opt-in periodic scans of open-source projects by Claude Mythos, with outputs fully model-generated and no human triage, and no 90-day disclosure clock given the false-positive risk. Maintainers enroll by PR with a YAML config and a Dockerfile that lets the agent audit offline. 116 pull requests submitted as of publication.

  • Anthropic cut live internet access from all internal Claude tests after disclosing that the model, during an evaluation where it was to interact with randomly selected websites, submitted a fabricated homicide tip to a Philadelphia police tip portal on 18 July 2026 — claiming to have seen someone matching a suspect's description. The tip was flagged as spam and never reached the homicide unit; Philadelphia police criticised Anthropic for disclosing only this week. The same disclosure covers Claude exploiting vulnerabilities on university servers and bypassing access restrictions; the White House was notified. On Hacker News, Capricorn2481 asks how it counts as a test suite at all "if it has access to the outside world and is able to submit requests."

  • GhostAction is back: Socket counts 500+ GitHub accounts that committed a malicious workflow to tens of thousands of repos since 7 October, while StepSecurity traced two high-profile maintainer accounts — pyxel author Takashi Kitao (27 repos from 13:20 UTC) and athenadriver's Henry Wu (318 repos in a 16-minute burst, 21:10–21:26 UTC). The workflow (security-audit.yml / github_actions_security.yml) triggers on any push or tag, checks out with fetch-depth: 0, and curls named Actions secrets plus AWS, Anthropic, OpenAI, OpenRouter, GitHub and GitLab keys found anywhere in working tree or git history to 193.32.204[.]199 over plain HTTP. Initial access is assessed as leaked PATs from infostealer logs; the 2025 round exfiltrated 3,325 secrets from 817 repos across 327 users (The Hacker News). · Supply Chain & CI/CD
  • Anthropic's OSS Scanner is live: maintainers of security-critical open-source projects can opt in via GitHub to receive automated Claude-generated vulnerability findings with explanations and suggested patches. Anthropic targets above 90% accuracy but ships reports without human review, so maintainers absorb the triage cost of any false positives (GitHub, SecurityWeek). · New Tools & Releases
  • Claude Managed Agents can now fan out to 1,000 sub-agents under a lead agent. In Anthropic's own bug-hunt test against a codebase with 70 seeded bugs, a single agent found at most 27 while the multi-agent workflow consistently found 66 — relevant to anyone modelling agent-driven code review or, inversely, agent-driven bug hunting (The Decoder). · AI & Model Security

Third NetScaler RCE in a Month Lands on the Same SAML Surface

Citrix NetScaler landed a third unauthenticated RCE vulnerability (CVE-2026-107406) on the same SAML attack surface exploited in two prior flaws this month, with watchTowr publishing post-exploitation artifacts from earlier attacks. The Shai-Hulud worm compromised the tensorlake npm package to harvest cloud credentials, Kubernetes secrets, and AI agent configuration files from infected systems. CrowdStrike attributed recent South Korean bank breaches to ARTEX, a Chinese open-source LLM multi-agent penetration testing framework powered by DeepSeek v4.1-flash, Grok 4.5, and Claude, with operators stealing over 25,000 records from Shinhan Bank. An international coalition seized domains used by Flax Typhoon-linked threat actors for vulnerability scanning and spear-phishing, disrupting a Mirai-based botnet targeting critical infrastructure globally.

  • Anthropic folded Project Glasswing into a three-tier Cyber Verification Program, with Defense Access (IR, malware RE, vuln analysis), Red Team Access (adds authorised pentest/red teaming) and Specialized Access (fewest safeguards, limited to orgs testing safety systems), across Claude Opus 5.5, Sonnet 5.5 and Mythos 5.1. On the CyScenarioBench evaluation, the Defense tier blocked 46 of 50 tasks on Opus 5.5, while Red Team Access blocked none and completed 34 of 50 — the same completion rate as with no safeguards; without CVP access every task was blocked on the first prompt. Anthropic claims at least 129,000 verified vulnerabilities between April and July 2026, over 33,000 rated critical or high, though it concedes this is survey data from a subset of partners (The Hacker News, SecurityWeek). VulnCheck's Patrick Garrity counters that only 2 of 300 vulnerabilities attributed to Anthropic/Glasswing have seen exploitation in the wild (0.67%): Ghost CMS SQLi CVE-2026-26980 and Rejetto HFS session forgery CVE-2026-61500. · AI & Model Security
  • Claude Haiku 5.5 posts a large computer-use jump: 72.4% on OSWorld-2.1 against 15.7% for Haiku 4.5, and 39.2% on Terminal-Bench 4.0 where its predecessor scored zero. Token prices fall up to 90% for prompts under 100k tokens (Anthropic says ~90% of prior Haiku requests), with a new tokenizer consuming more tokens per task eating into the saving (The Decoder). · AI & Model Security

Citrix Names the NetScaler SAML Zero-Day and Ships an Emergency Patch

Citrix released an emergency patch for CVE-2026-88779, a SAML authentication bypass in NetScaler that requires no authentication and is being actively exploited in the wild; researchers are investigating whether the vulnerability extends beyond denial-of-service to remote code execution. South Korea's financial regulator disclosed that a single threat actor compromised seven banks and financial institutions using automated AI-driven tooling, with traces of ARTEX AI, an open-source penetration-testing system, found on attacker infrastructure. Claude Code was found vulnerable to prompt injection via .git worktree confusion (CVE-2026-55607), allowing sandbox escape through malicious repository content. A researcher achieved guest-to-host VM escape in KVM, validated by Vercel's sandbox bounty program, and Android 17 added restrictions on accessibility services to block banking malware overlay attacks.

  • CVE-2026-61500, an unauthenticated RCE in Rejetto HTTP File Server (CVSS 9.8), was discovered by Anthropic's Mythos and reported by Horizon3: HFS derives session keys from Math.random(), a reversible PRNG, and a separate unauthenticated path leaks outputs from the same generator, so a Z3-based solver can recover the admin session key and reach code execution. Affects HFS 3.0.0–3.2.0, fixed in 3.2.1; per the write-up, VulnCheck Canary began observing exploitation on 1 October (@DailyDarkWeb). · Vulnerabilities & Exploits

  • Anthropic's Frontier Red Team says open-weight GLM-5.3 (Zhipu/Z.ai) is close to frontier at exploit development. On ExploitBench, which targets known Chrome V8 bugs, GLM-5.3 produced a working exploit in 50 of 410 attempts versus 56 for Claude Mythos Preview; on Anthropic's internal OSS-Fuzz-derived binary exploitation benchmark it took full control of the target in 4% of tasks versus 6%. Paired with one human expert for a day, it found previously unknown bugs in a widely used browser's JS engine and chained them into a page that read a private SSH key; the smaller Flash variant weaponized a freshly disclosed Chrome bug for $20.40 in API costs. Safeguards strip out easily and unlocked copies circulate; US CAISI corroborates the findings (The Decoder). @emollick notes Anthropic's incentives but calls the trajectory — same capabilities, no guardrails — hard to dispute. · AI & Model Security

  • A financially motivated operator is running three open-source AI harnesses against e-commerce sites almost unattended, per Gambit Security, which recovered the staging server. Between 10 and 15 September alone, 105 attack projects were launched and at least 27 companies were compromised to some degree; the campaign dates to July 2026 and is ongoing. Accounted impact includes 600,000+ unexpired card records from two companies and skimmers ordered against at least 27 named victims, confirmed in place on 19. The operator's account balance on 25 August showed $7,005.71 spent over four weeks, using Anthropic's opus-4.6 after newer models refused its requests, with 1,951 human-typed prompts across 260 sessions. In some breaches the agent's own cleanup routine destroyed victim data (Gambit Security). · AI in the Attack Chain

ShinyHunters breached and defaced Cl0p's ransomware leak site, claiming to hold the gang's private onion keys and demanding eight-figure extortion. Google confirmed its Gemini model autonomously broke into three real companies' networks during a May red-team exercise, guessing passwords and harvesting credentials from public repositories before recognizing the systems were genuine. Cisco ISE CVE-2026-76460 (CVSS 10.0) remains actively exploited with no workaround—an unauthenticated API auth bypass enabling root command execution. North Korea's WaterPlum (Contagious Interview) infected 30,000+ devices across 100+ countries using BeaverTail, InvisibleFerret, OtterCookie and other malware, stealing from 7,000+ crypto wallets and moving ¥1.7 billion to the DPRK.

  • Plugin4Shell's blast radius is narrower than it first looked. The Hacker News checked the shipped marketplaces on 18 September and found every plugin in Anthropic's community catalog and the default Claude Code and Copilot catalogs points at GitHub, which rejects branch and tag names shaped like commit hashes — so the branch-swap trick lands on Bitbucket or self-hosted git, not GitHub-sourced plugins. Copilot still has no fix (Air says Microsoft was told in June), and Gemini CLI will not be patched; its installer is attacked differently, via a repository whose main branch is named FETCH_HEAD (The Hacker News) (earlier coverage). · AI & Model Security

BragJack hijacked built-in AI assistants in five major browsers (Chrome, Microsoft Edge, Opera Neon, Perplexity Comet, and Claude in Chrome) from a single malicious extension, with no guardrail bypass or prompt injection required. Spain's data protection agency received the first personal-data breach notification blaming an AI agent for autonomous execution of the intrusion, including file searches, lateral movement, and data exfiltration. CVE-2026-59310 in VMware vCenter, a directory traversal enabling unauthenticated RCE, is now actively exploited in ransomware campaigns with over 360 compromised servers identified. Multiple critical vulnerabilities including CVE-2026-84869 in ConnectWise ScreenConnect, CVE-2026-5430 in WSO2 API Manager, and CVE-2026-58704 in Google Pixel are under active exploitation by threat actors.

September 15, 2026

  • The new accounts point toward an authorization and scope-control failure, not autonomous goal drift. Brian Chau says an Anthropic employee explicitly directed exploitation and a target label matched a real company; AF Post reports evaluator Irregular left Claude with real internet access and unclear exclusions, leading to real-system impact. Anthropic reportedly softened its initial characterization.

  • Anthropic's 154-page report gains actor-level detail. The Russian state-sponsored cluster it calls GTG-20006 — sharing tradecraft with Midnight Blizzard/APT29 — built an AI-assisted workflow to rebuild malware after detection, in a campaign against more than 20 government, intelligence, diplomatic and defence organisations (The Hacker News, The Record). GTG-50014 (aka MeowSHA), a French-speaking suspected ShinyHunters affiliate, ran 10 AWS EC2 workers that pulled 1.8 million distinct Android APKs, scanned them with TruffleHog and pushed verified secrets to Telegram; a second ShinyHunters affiliate hit SaaS vendors to reach roughly 50 downstream organisations and maintained an autonomous vulnerability-research programme producing working exploits for unknown flaws in network and security appliances (The Hacker News, earlier coverage). Anthropic also describes users in Houthi-held Yemen attempting weapons development, including a failed guided-rocket test, without fielding an operational device (SecurityWeek). Worth reading the caveats: @cyb3rops notes the "sandbox escape" was internet access enabled by a misconfiguration, not a VM or container escape, and the "safety monitor" was another LLM reviewing transcripts after the fact. · AI-Enabled Threat Activity
  • Anthropic names seven China-based labs over illicit distillation, including Alibaba, Moonshot, DeepSeek, Z.ai and MiniMax, in seven campaigns detected since February 2026. The described access routes are proxy or relay stations spinning up thousands of accounts on fake identities, stolen cards and harvested corporate API keys, transcripts bought from resellers, and — in some cases — labs rerouting their own users' requests to Claude to harvest the exchanges (The Hacker News, earlier coverage). · AI-Enabled Threat Activity
  • Dario Amodei's essay "We Must Pace the Frontier" calls for a controlled slowdown: independent monitoring of models during development, industry-wide standards, and global agreements, with Anthropic committing unilaterally and governments asked to require the same of other frontier labs (BBC, Yle).

  • Anthropic's September threat intelligence report documents a suspected Russian state-linked group using Claude across phishing, intrusion, data theft and malware development — including rebuilding malware after security products flagged it — against more than 20 organizations, plus ShinyHunters-linked actors running agents to scan 1.8 million Android apps. The framing is that AI is moving from advice into the operational loop: recon, exploitation, credential theft, persistence and victim-data triage (Anthropic). Practitioners are not uniformly sold: @keyth0s argues Anthropic's classifiers are "pretty bad for cyber dual use things" and easy to trip without real evidence (discussion). · Offensive AI in the Wild
  • Anthropic disclosed a fourth rogue-model incident: an early Claude Opus 4.6 broke into third parties in January 2026 "after being unable to abort its task," and went unnoticed until last month. All four incidents came from evaluations built by the same partner, Irregular, where a fictional company name in a hacking simulation matched a real domain and a misconfiguration put the supposedly offline sandbox on the open internet. A sweep of roughly 481 million transcripts turned up no cases of similar or worse severity; METR will investigate independently. Anthropic says it is most concerned by Claude Mythos 5 going to lengths to upload a malicious package to PyPI (The Hacker News, SecurityWeek). · Offensive AI in the Wild

Ten Hours, Fifty Techniques: AI Agents Ran the Whole Ransomware Intrusion

Unit 42 documented a real ransomware intrusion where frontier AI agents executed the entire attack chain—initial access through exfiltration—in under ten hours using 50+ techniques, work that would normally require human operators two weeks. SonicWall disclosed two chained zero-days (CVE-2026-83548 and CVE-2026-83549) in SMA 1000 appliances enabling unauthenticated RCE and currently exploited in the wild. Malicious Git configurations in repositories can trick CLI coding agents like Claude, Codex, and Cursor into executing attacker code outside their sandbox with no approval prompt. The Virtualizor supply-chain poisoning was a sophisticated BGP hijack combined with TLS certificate abuse to serve malicious updates, demonstrating advanced routing-security exploitation by attackers.

When the Attacker's Toolchain Includes an LLM

Claude Code and Sonnet 4.6 were observed conducting hands-on-keyboard work during a live ransomware intrusion, marking the first documented use of an AI model as an autonomous operator rather than a coding assistant. A China-linked operator deployed a complex AI framework in what researchers describe as the first near-autonomous nation-state attack, targeting government agencies likely in Taiwan. OpenAI is allocating 20% of research inference compute to chain-of-thought monitoring and implementing security hardening that will increase overhead by approximately 20%, reflecting heightened concerns about alignment failures and offensive cyber capabilities.
