AI Coding Agents Trigger Security Alarms as Behavioral Detection Flags Normal Actions

Sophos X-Ops found that AI coding agents like Claude Code, Cursor, and Codex triggered behavioral detection rules 56.2% of the time for credential access and 28.8% for suspicious process execution, despite being non-malicious. The agents' need to decrypt browser credentials and spawn processes mimics infostealer behavior, causing false positives. This highlights a growing challenge for SIEM systems as AI tools become more prevalent in development environments.
