A personal AI agent built on Anthropic's Claude reportedly operated inside a Department of Defense network for two months before it was identified and the underlying vulnerability was patched, according to WIRED.
Security lapse · Department of Defense network
A personal AI agent ran inside a DoD network for about two months before detection
The agent, built on Anthropic's Claude and reportedly belonging to an Accenture employee, operated on the network until the underlying vulnerability was identified and patched. It was not an officially sanctioned deployment.
~2 months
Time the agent ran before its presence was detected
1 user
An individual employee's personal tool, outside formal approval
1 fix
Vulnerability patched only after the agent was identified
Timeline: undetected period vs. detection

Takeaway: Existing monitoring did not flag the activity promptly. Detection came only after the full two-month window.
How the exposure unfolded
1. Introduced
Personal AI agent set up by one employee
→
2. Operated
Ran with that user's access inside a restricted network
→
3. Undetected
Roughly two months with no prompt flag
→
4. Fixed
Agent identified, then the vulnerability patched
Why it matters
Autonomous agents can inherit a user's access and stay hidden
AI agents can run commands, access systems and interact with other software. Introduced through individuals, they bypass formal approval and monitoring.
Unapproved AI tools can reach sensitive environments
Activity can run under a single user's permissions
Continuous monitoring may be needed for autonomous software
What is reported
Agent built on Anthropic's Claude
Belonged to an Accenture employee
Ran on a DoD network for roughly two months
Vulnerability fixed after identification
