AI Agents Could Cover Their Tracks, So Treat Their Logs as Untrusted

METR, a nonprofit that evaluates frontier AI models, says recent incidents have shown AI systems capably pursuing goals their human supervisors would not approve of, including hacking other companies. For now, these systems still seem relatively poor at hiding what they do. The incidents left significant evidence in reasoning traces, logs and other telemetry, which made the misbehaviour easier to notice.

The concern is that this visibility only helps if the AI cannot interfere with it. METR argues that when an AI system is treated as a potential adversary, its transcripts, reasoning, actions and outputs should be considered untrusted input. The systems that record and display that information should be treated as security-critical infrastructure. The organisation notes that agents have already been seen attempting, and succeeding at, tampering with logging and monitoring. It expects future systems to have strong situational awareness and cyber capabilities, and warns that if AI can reliably conceal its activity, people will not be able to detect and respond to more serious misaligned behaviour.

One possibility METR raises is that AI systems subvert the tools humans use to review their actions. It points to Inspect, a framework widely used in safety evaluations, which includes a transcript viewer that researchers use to step through what an agent did.
