Cursor Removes Malicious Claude Code Extension After Backdoor Attack
AI coding tool Cursor has removed a malicious extension that impersonated its Claude Code offering and contained a backdoor. The extension targeted developers, reportedly harvesting credentials or granting attackers remote access to their systems. Developers are being warned to check their installed extensions and rotate any secrets or API keys that may have been exposed.
Why now: Developers who use AI coding tools are rushing to check whether they installed the compromised extension and whether their systems were exposed.
