Epoch AI had GLM 5.3 build working Firefox exploit chains for about $1,000 each, Mistral put a trillion-parameter model with strong cyber scores on Hugging Face, and the tools developers install were hit directly: a trojanized official Claude Code extension went out through the Cursor marketplace under Anthropic's own extension ID.

TLDR

Trojanized Claude Code extension 2.1.313 reached up to 5,000 Cursor users with an SSH backdoor (Oct 30); Anthropic's clean 2.1.314 is out. Security Agents

Action Items

Search every Cursor and VS Code install for anthropic.claude-code version 2.1.313 today, and update to 2.1.314. On any hit, remove the svc-telemetry key from ~/.ssh/authorized_keys, delete the new Task Scheduler entry, crontab or LaunchAgent, and block 134.209.82[.]225.
Upgrade Drupal Commerce Core to 3.3.13 (3.x) or 8.x-2.41 before the weekend. CVE-2026-118539 is exploited and can cost a store money.
If you load DebugBear's real-user-monitoring snippet, pull it from every page that handles wallets or payments until the vendor clears the incident.
Cut browser update lag on managed fleets to under 24 hours. Epoch's Firefox exploits worked in the days between a public fix and its release to users.
Do not set trust_remote_code=True on Hugging Face models you have not read, and audit Xinference and GPUStack hosts for unknown processes.
