According to Sophos researchers, AI coding agents, such as Claude Code, Cursor, Codex and others are activating attack detection rules written to catch human intruders, but in reality they are not malicious. From the perspective of an endpoint behavioral engine, some of that activity is indistinguishable from typical activity seen on customer networks – or, in some cases, from actions that might be undertaken by an active adversary.
Scott Miserendino, Chief Technology Officer at DataBee, A Comcast Company, provided the following comments:
“This is not surprising at all and we will likely see many more examples in the future. Endpoint detection and response vendors, such as Sophos, however, are accustomed to dealing with software that can act like an attacker. They have multiple techniques for tracking and whitelisting the combination of the process creator and behavior to reduce false positives from legitimate behavior. The question is how aggressively the EDR community is keeping up and maintaining these rules and detection tweaks to achieve acceptable false positive rates. One potential beneficial side-effect of identifying these subtle behavioral patterns of AI agents is it provides a signal of AI use even when users (or attackers) may be trying to obfuscate the use of AI to avoid policy enforcement.”
AI has to be a central part of your security strategy. Simply put, the days of AI living in a silo is over and modern security has to reflect that. Or else.
