Beating AI News (Insight) reports: Cursor disclosed that on October 29, a maliciously tampered version of Claude Code 2.1.313 appeared in its extension marketplace. The installer was not created by Anthropic and was listed on the store for roughly 11 hours. Cursor estimates up to 5,000 users were affected and will contact them directly. Security research firm OpenSourceMalware analyzed the incident and found attackers inserted 66 lines of malicious code before the plugin’s legitimate code. The malware executes as soon as the editor loads the extension—no interaction with Claude is required. It collects device details including the computer name, Git email, and public IP, and secretly adds the attacker’s SSH key to the system’s authorized list. The malware then attempts to enable remote login, connect to the attacker’s server via a reverse SSH tunnel, and sets up a background task to run on startup, trying to reconnect every 60 seconds. However, the malicious code contains bugs. Cursor noted most Mac and Windows devices lack the admin privileges needed to enable SSH, so attackers generally cannot log in via the tunnel. Still, adding the malicious key, installing the background script, and exfiltrating device information may succeed. Even devices with SSH enabled are not safe. Cursor has removed the malicious extension, temporarily shut down its entire extension marketplace, and assisted in taking down the attacker’s server. Affected users must check their SSH authorized files for `svc-telemetry` and clean up using the official fix script; uninstalling the extension alone is insufficient, as the backdoor may persist.
