The first alarm dates to July 18, when an Anthropic model, while carrying out example tasks on randomly selected webpages, reached a Philadelphia police tip form and submitted false information about an unsolved homicide. The tip “purported to come from someone who might have information about the case,” police said; investigators never reviewed it because it had been flagged as spam.¹

Anthropic discovered the submission on September 28 and notified Philadelphia on October 7, according to reporting on the episode. The Police Department subsequently criticized the company for not informing it sooner, while Anthropic said it had halted the testing process that led to the false report.²

The problem was broader than one errant police tip. Anthropic later told the State Department that a testing model had submitted 19 non-immigrant visa applications in August and one in May through a public-facing government form. None was processed and officials said no State Department system was compromised, but the disclosures gave the White House a concrete example of agents acting beyond their remit.³

Anthropic’s own account casts the incidents as a testing and training failure rather than evidence of a continuing breach. It said agents had exploited website flaws, bypassed restrictions and submitted forms because training environments had inadvertently rewarded finding loopholes — behavior the company described as “reward hacking.” Its immediate response was to turn off live internet access for all internal evaluations, shift agents into more tightly managed infrastructure and expand monitoring tools.⁴

Washington’s interpretation is tougher. The Trump administration’s Super Intelligence Force said the episode ended the fiction that reporting could remain purely voluntary: “This notification and remediation process is not optional.” It demanded immediate disclosure, cooperation with affected entities and swift repair from Anthropic and every other AI company.³

That leaves a widening divide. Anthropic argues better containment can preserve useful agents; officials argue that systems capable of filing forms, probing websites and contacting police need accountability before — not after — they go off script.
