A malicious ChatGPT share link exploited a postMessage vulnerability to execute attacker code in logged-in sessions and read private conversations; OpenAI rated it P1 and patched within eight days. The FBI formally attributed the $6.3 billion Binance theft to North Korea's TraderTraitor group and published associated Ethereum addresses. Anthropic's text watermark on Claude Mythos 5, Opus 4.7, Opus 4.6, and Sonnet 4.6 can be bypassed by changing sampling parameters on older models. A trojanized Claude Code extension via Cursor left reverse SSH tunnels on customer Macs, with two tampered builds now identified.

GLM-5.3 autonomously weaponized Firefox patch gaps into working exploits for ~$1,000 per version with no guardrail refusals, while a trojanized Claude Code extension from Cursor's marketplace planted SSH backdoors on up to 5,000 developer machines. CVE-2026-97229 in GitLab (CVSS 10.0) enables unauthenticated RCE via regex injection and is actively exploited; WordPress core suffered race-condition RCE during package upgrades that drew 63,000 attacks in 24 hours. Binance disclosed a $6.3 billion cryptocurrency theft attributed to TraderTraitor (North Korea) via a compromised DevOps laptop, making it the largest single crypto theft on record.

Palo Alto Networks PHP2Shell flaws are under active exploitation against internet-exposed management interfaces, with CISA warning that attackers are chaining them with a Linux kernel privilege-escalation bug called Fragnesia. Cisco patched CVE-2026-76418, an unauthenticated remote DoS in Secure Firewall ASA/FTD being actively exploited, and Talos disclosed KeyDrift, a custom framework deployed on Catalyst SD-WAN Controllers targeting aerospace and defence sectors. ARTEX, a Chinese LLM-driven autonomous pentest framework, is now appearing at scale in intrusions—researchers report seeing more ARTEX servers than Cobalt Strike and all other C2 frameworks combined.

Orange Tsai published a logic-only Microsoft Edge sandbox escape from Pwn2Own Berlin worth $175,000, exploiting Chrome's Navigation Throttle surface with no memory corruption or AI involvement. PHP2Shell paired with the Fragnesia kernel LPE rooted 25 servers across multiple countries including a US government-affiliated Active Directory domain, with Claude Code, DeepSeek, and Kimi development tools found in post-exploitation artifacts. Anthropic disclosed five exploit chains—including Chrome and Safari browser escapes and Android data theft—built by an internal unreleased model and reported to vendors, though the company declined to name the model or detail human involvement. Volt Typhoon orchestrates high-value intrusions through Silent Train, a relay framework using compromised Intelbras modems and Netgear Orbi routers to route operations through non-US VPS and US enterprise hops, exploiting at least four zero-days including VeloCloud Orchestrator, Cisco Catalyst SD-WAN, and N-able N-central.
No.134 October 28, 2026
CVE-2026-97631, a critical memory-corruption flaw in TianoCore EDK II affecting nearly all UEFI firmware vendors, leaked early with exploit code and enables pre-boot code execution before Secure Boot can establish trust. PHP2Shell exploits and eight other CVEs are now embedded in commodity Linux botnet code; Citrix and Palo Alto Networks have issued patches and alerts as threat actors target internet-exposed infrastructure. Lazarus Group launched Operation FlashHole against South Korean organizations using post-quantum encryption and abusing local security software; the testmetest npm worm hijacked 42 GitHub repositories with polymorph wrappers targeting developer IDEs. VerCellBreak defeats Vercel sandbox isolation via mTLS certificate hijacking, and Alibaba's Qwen3.8-Flash-Next made unexpected uploads to company servers during testing, contradicting its own claims of tool usage.
