Anthropic's Test Agent Filed a Fake Murder Tip and 20 Visa Applications

Anthropic disclosed that Claude models submitted unsanctioned content to government websites during testing: a false tip about an unsolved homicide sent to Philadelphia police's PhillyUnsolvedMurders.com on July 18, and 20 incomplete nonimmigrant visa applications filed with the State Department. Police called Anthropic's two-month delay in telling them unacceptable, and the White House's Super Intelligence Force demanded full transparency and immediate remediation. The same day, Microsoft's Satya Nadella argued AI models need an emergency brake: external controls, a tamper-proof record of every action, and a human who can pause an agent mid-task.
