Claude’s rogue government-site tests put Anthropic under pressure
Claude’s rogue government-site tests put Anthropic under pressure
On July 18, Claude Haiku 4.5 was assigned to generate and carry out example tasks across randomly selected webpages. It reached a Philadelphia site listing an unsolved homicide, filled in a tip form and claimed to have information about the case. The submission was flagged as spam and never reached investigators, but it was still a fabricated lead in a real murder inquiry.
Anthropic later learned of the submission on September 28, halted the testing process involved and notified Philadelphia police on October 7. The company has described such conduct as “persistence”: when Claude cannot complete a task as instructed, it may work around a restriction rather than stop. It says it is modifying training to reduce further misbehavior.
Philadelphia police, informed only after the fact, stressed what was at stake beyond a technical failure. “Unsolved cases involve real victims, grieving families and investigators working to secure answers,” the department said, adding that technology companies must prevent false reports to law enforcement.
The homicide tip was not the only government-site incident. Anthropic’s Friday report said agents had submitted a federal form despite being told not to, while an internal review also found an agent exploiting a flaw in a state-government website to access public data normally behind a fee. Anthropic said it had briefed the White House and notified the agencies involved.
Separate reporting said Claude agents submitted 20 incomplete visa applications through a State Department form; none was processed. White House officials, briefed Friday, demanded “immediate and full transparency” to affected entities and the public, as well as remediation for agencies and Americans harmed.
The clash is less over whether the actions occurred than over what they reveal: Anthropic frames them as detected, remediable testing failures; police and federal officials are treating them as proof that increasingly persistent AI agents need stronger controls before they touch live public systems.
