AI Agents Gone Rogue: The Evidence That Decides Blame

Emily Davis · 2026-10-26

When an AI agent goes off the rails, it's not just a glitch—it's an incident. And according to new guidance from NIST, CISA, and NSA, these runaway agents should be treated like any other security incident: something you rehearse for. But here's the kicker—the hardest part isn't stopping the agent. It's figuring out whose authority it was acting under. And that answer needs to exist before the incident even happens. ### The Incident Is the Agent Think of it this way: if a rogue employee starts causing chaos, you don't just fire them and move on. You need to know who gave them access, what permissions they had, and whether they were acting within their scope. Same goes for AI agents. When one goes rogue, the first question is: whose authority did it use? That's the evidence that determines liability, accountability, and how you fix the problem. But here's the thing—most organizations aren't prepared to answer that question. They treat AI agents like magical black boxes, assuming everything will be fine until it isn't. The new guidance flips that script. It says: rehearse for the worst. Simulate an agent going haywire. Then trace back the authority chain. If you can't, you've got a bigger problem than the incident itself. ### Why Identity Records Matter An identity record isn't just a log entry. It's the paper trail that proves who authorized what. For AI agents, that means every action should be tied to a human or system that granted permission. Without that, you're left pointing fingers in the dark. And in a regulated industry, that's a recipe for fines, lawsuits, and reputational damage. So what does a solid identity record look like? It starts with clear delegation. Who created the agent? What role was it given? What are its boundaries? Then, every time the agent acts, it should log the authority it's using. That way, when something goes wrong, you can replay the tape and see exactly where things went off the rails. ### Rehearse Like It's Real The guidance emphasizes tabletop exercises. Gather your team, simulate an AI agent incident, and walk through the response. Who do you call? How do you revoke access? How do you trace the authority? These drills expose gaps before they become real problems. But don't just focus on the technical side. The human element matters too. Who has the authority to shut down an agent? What's the escalation path? These questions need answers, and they need to be practiced. > "The time to figure out who's in charge is before the crisis, not during it." ### The Bottom Line AI agents are powerful, but with great power comes great responsibility—and that responsibility needs to be documented. The new NIST, CISA, and NSA guidance is a wake-up call. Treat runaway agents as incidents. Rehearse your response. And most importantly, ensure that every agent's authority is recorded and traceable. Because when the incident happens, the identity record is your best evidence. And it has to exist before the incident does.
