AI Coding Agents Triggering Endpoint Security Alerts Designed for Attackers

AI coding agents such as Claude Code and OpenAI Codex are triggering endpoint security rules designed to detect attacker behavior, as their actions mimic malicious activities like credential decryption and system tool usage. This creates challenges for threat detection, requiring adjusted security strategies to differentiate between benign AI operations and actual threats.

Sophos looked at a week of its own endpoint data and found that AI coding agents such as Claude Code, Cursor, and OpenAI Codex are setting off detection rules written to catch human intruders.

The agents are not malicious. They just do a lot of things that, to a behavioral engine, look exactly like an attack.
