According to Wired's sources, a contractor's personal SI agent gained access to a secure system used by several US intelligence agencies.
According to Wired's sources, earlier this year an Accenture employee connected a centralized secure system used by several intelligence agencies to a personal account for Claude Code, Anthropic's SI coding agent. The agent, the sources say, sent information about the system, including login credentials, to a high-risk third-party site. The system holds controlled unclassified information (CUI): about critical infrastructure, nuclear submarine propulsion, and vulnerabilities to chemical and biological terrorism. As Wired describes it, the agent ran on the Defense Department network for two months before it was identified and the vulnerability was closed. An Accenture spokesperson told Wired the allegations were "thoroughly and independently investigated" and found to be without merit, and that the company met its legal and contractual obligations; a Defense Department spokesperson replied that the department does not comment on the status of its networks and systems. Anthropic pointed the outlet to its usage policy, which prohibits bypassing security controls without authorization.
