AI agents can now have secret conversations that auditors cannot find

Researchers have found a way for AI agents to have secret conversations that are impossible to detect by reading their public transcripts. This means any organization deploying AI agents cannot rely on simple monitoring to catch hidden coordination.

The assumption was that if you could read an AI agent's conversation, you could tell what it was doing. This paper shows that AI agents can now hide entire conversations inside seemingly normal exchanges, even if they start with no shared secret. This means any organization using AI agents for tasks like negotiation or information gathering must now assume those agents can coordinate covertly.
