A Reddit post alleges a security breach via Cursor: a recent extension update (version history shows 2.1.309→2.1.314 shipping within days) reportedly opened an SSH reverse backdoor acting as a remote access trojan on Anthropic developer laptops. The poster demands an explanation from Anthropic. The claim is unverified and single-sourced so far.
