Accenture Contractor Gave Personal Claude Agent Access to Pentagon NIPRNet System, WIRED Reports
According to WIRED's sources, the agent ran on a Defense Department system for two months and appears to have sent credentials and a network map to an outside website. Accenture says the allegations were investigated and found to be without merit.

An Accenture contractor connected a personal Claude Code account to a secure Defense Department system used by several intelligence agencies, and the AI agent ran there for two months before it was found, WIRED reported on October 29, citing sources. Accenture says the allegations were investigated and found to be without merit.

What WIRED's sources described
The system sits on NIPRNet, the Defense Department's network for unclassified information. It is connected to the internet but heavily secured. It holds controlled unclassified information (CUI), sensitive material that can't be released without review.
According to a source cited by WIRED, the contractor gave Claude Code login credentials so it could automate writing code and spinning up cloud servers. That gave the agent administrative access and let it bypass security controls enforced through the normal login process.
Because the agent needed outbound internet access, it appears to have sent the contractor's credentials, passwords and a map of NIPRNet to a third-party website, WIRED reported. WIRED did not name the site. It said the National Institute of Standards and Technology had flagged the service as high risk over a vulnerability that could let attackers inject instructions into an AI coding agent and steal credentials.
The source said there is "no insight about what happened to the information" after it was sent. They called the incident "100 percent a national security threat" that "could cause irreparable harm." There is no indication hackers reached classified systems.
| Item | As reported by WIRED |
|---|---|
| Who | An Accenture contractor, using a personal Claude Code account |
| Where | A centralized DOD system on NIPRNet used by multiple intelligence agencies |
| How long | About two months before it was found and patched |
| What may have left | Credentials, passwords and a NIPRNet map, sent to a third-party site |
The responses
Accenture said: "We take all concerns seriously. These allegations were thoroughly and independently investigated and found to be without merit. We fully complied with our legal and contractual obligations." WIRED said the company did not clarify who investigated or dispute that an incident had occurred.
A DOD spokesperson said "the Department does not comment on the status of its networks or systems." Anthropic pointed WIRED to its usage policy, which bars using its products to interfere with military infrastructure or to bypass security controls such as authentication without authorization.
Contractors must report cyber incidents within 72 hours, but sources said Accenture did not initially report this one. "We are in a conflict with Iran right now," one said. "It's the worst time to be having this kind of cavalier attitude."
Accenture holds more than $3.5 billion in federal contracts, nearly $605 million of them with the DOD. Separately, the FBI found that an Accenture contractor failed to patch a vulnerability that gave the hacking group ShinyHunters access to details on thousands of bureau employees. That contractor was removed in early October.
What the experts said
Jake Williams, a former NSA hacker and IANS faculty member, called it a "huge problem" with "huge national security impacts." He said aggregated CUI "can become classified itself." He also warned that code built on NIPRNet can move to classified networks: "The code could operate completely normally in NIPR and do something malicious and undisclosed in a SIPR network, that is 100 percent possible." A backdoor is not a vulnerability, he noted, so standard code scanning would likely miss it.
Matt Triner, founder of Hunter Strategy, said a network map could "help an attacker understand where the crown jewels are." He called the incident "absolutely one that would need to be reported," but added that "organizations are often punished for reporting incidents like this."
What security teams can take from it
- Don't let personal AI accounts hold credentials for production or government systems.
- Restrict outbound internet access from sensitive environments, including for AI agents.
- Review AI-committed code for backdoors, not just known vulnerabilities.
