Item one: Help with a malicious programming add-on
Item one: a malicious programming add-on. Cursor is an app for writing computer programs. It offered a tampered Claude Code add-on October 29, about 2:27 a.m. to 1:35 p.m. Pacific. If you installed or updated it through Cursor on Windows or Mac then, it tried to leave a way back into your computer. Removing it alone may leave malicious files behind. Cursor says the attacker’s server is offline, but cleanup may still be needed. Not comfortable checking? Email security@cursor.com, the contact in Cursor’s notice, to ask about your installation and cleanup. You don’t need to tackle unfamiliar commands yourself.
