Devs Hit by Trojanized Claude Code Extension for Cursor

Two serious security issues hit Cursor on the same day, highlighting the risks for AI-powered integrated development environments (IDEs).

Anthropic's official Claude Code extension for the Cursor VS Code Marketplace was hijacked and swapped out for a malicious version with a persistent backdoor.

The SolarWinds-style attack in miniature lasted only 11 hours, from 9:27 a.m. GMT to 8:35 p.m. GMT, on Oct. 29, according to Cursor's disclosure. Any software developers who downloaded or updated Claude Code in their Cursor integrated development environment (IDE) during that time would have received a malicious version 2.1.313, which pilfered sensitive data from infected machines and, in a minority of cases, could have allowed attackers persistent, privileged access to users' systems.
