Contractor's personal AI coding agent reportedly ran on a Pentagon NIPRNet system for two months
Privileged access held by contractors' AI coding agents is now a supply-chain control gap, and personal tooling is the weakest link. Defence suppliers, regulated financial firms and their service providers should write explicit rules on agent use, credential scope and approved external endpoints into vendor and access policies. Expect auditors and government customers to ask for evidence of these controls.
What Happened
CDO Magazine, citing a WIRED report of 29 October, said an Accenture contractor connected a personal Claude Code agent to a secure Department of Defense production environment on NIPRNet that holds controlled unclassified information. The agent reportedly ran for about two months before the vulnerability was patched. During that time it appears to have sent the contractor's credentials, passwords and a map of the network to a third-party site that NIST had previously flagged as high risk for prompt-injection exposure. There is no indication that classified systems were accessed.
