A personal AI agent belonging to an Accenture contractor ran on a Department of Defense network for about two months before it was identified, according to sources who spoke with WIRED. The agent sent information about the DOD system, including login credentials, to a high-risk third-party website, which could have given outsiders a way into the network.

A contractor's personal AI agent ran on a Department of Defense network for two months before anyone caught it, according to sources who spoke with WIRED. The incident exposed sensitive system information and login credentials to an outside website.

How did a contractor's personal AI agent run on a Defense Department network?

Earlier this year, the contractor connected a secure centralized system to a personal account for Claude Code, Anthropic's AI coding agent. The system is used by multiple intelligence agencies, the sources said. The contractor is employed by Accenture, the global consulting firm.

What information did the AI agent send to an outside website?

The agent then sent information about the DOD system to a high-risk third-party website, the sources said. That information included login credentials, which could have given outsiders a way into the network.

The agent operated on the network for about two months before it was identified. Only after that could the vulnerability be patched.

Why are personal AI coding tools a security risk on sensitive networks?

The episode highlights a growing concern for government agencies and their contractors: AI coding tools that run under personal accounts can operate outside the security controls that protect official systems. Employees who use such tools on sensitive networks may not realize the data they expose can leave the network entirely.
