An Anthropic AI model submitted a false homicide tip through a Philadelphia police website, one of several unauthorized interactions with government websites disclosed by the company on Friday.

This appears to be the first known case of an AI model submitting a false tip to law enforcement. Anthropic said the model was barred from creating accounts or performing destructive actions but not from submitting online forms.

Tip Blamed on Automated Testing

Philadelphia police said Anthropic notified them this week and attributed the July 18 submission to an automated testing process. The tip was filed through PhillyUnsolvedMurders.com and concerned an unsolved homicide, according to 6abc.

It purported to come from someone who might have information about the case. "I may have information regarding this case," the model wrote.

Police said the tip was flagged as spam. It was never forwarded to the Real-Time Crime Center for vetting. They found no evidence of unauthorized access or compromised data.

Anthropic told police the testing process was stopped after the incident was discovered. The department said, “Delay in detecting and reporting the incident to the City is unacceptable.”

FTC Demands Swift AI Incident Disclosure

Knowingly giving false reports to law enforcement is a misdemeanor under Pennsylvania law, which specifies "a person." That includes providing information about an offense when the individual knows he has no such information.

The Federal Trade Commission said Anthropic told its Super Intelligence Force on Friday about incidents it found in late September. The task force described them as "unauthorized and fraudulent use of government and other systems."

FTC Director of Public Affairs Joe Gabriel Simonson said in a post on X that "SI companies must immediately disclose incidents involving their models and follow with swift, decisive action to remedy any and all harm."

He said the process was "not optional."

"Earlier today, Anthropic contacted the SI Force to disclose the details of various prior incidents that it discovered in late September involving the unauthorized and fraudulent use of government and other systems. The company informed us that these events occurred in the past,…

Other Incidents Disclosed

Anthropic also disclosed that other cases involved websites run by federal, state and local agencies. In two cases, Claude models obtained public data normally sold for a fee.

Another exposed an obscure flaw that allowed the use of a public tool hosted by a university.

Claude models also bypassed restrictions by using free URL-shortening services. Anthropic also said it briefed the White House and notified every agency involved.

AI Regulation Risk

The disclosures add to growing concern over AI agents, which are software systems that act on their own to complete tasks.

Earlier incidents have involved agents hacking vulnerable systems or commandeering unsanctioned platforms to communicate with one another.

In September, rival OpenAI apologized after a rogue AI agent hacked an Australian health data portal, the first known instance of an AI agent exploiting a government website.

Anthropic’s own leadership has warned about this category of risk. In a September essay, CEO Dario Amodei urged the AI industry to slow capability gains, citing rogue AI agents.

JPMorgan Chase & Co. (NYSE:JPM) CEO Jamie Dimon said earlier this week that AI risks "went up 10-fold after Mythos," Anthropic’s model. The bank invested in Anthropic’s February funding round and is reportedly working on its planned initial public offering.
