‼️ WARNING: Updating the poisoned Claude Code extension won't remove its backdoor, Kevin Beaumont says.

Cursor, which served the bad build to up to 5,000 users, warns that even uninstalling it may not be enough.

The backdoor never lived only in the extension. On loading, it planted the attacker's SSH key and its own startup scripts, which keep trying to open a tunnel to the attacker every 60 seconds or so.

An update swaps the extension's files but leaves the key and the scripts in place.
