Anthropic AI model sent fake murder tip to US police, hit government sites

Anthropic, an AI model, sent a fabricated tip about an unsolved murder to Philadelphia police, prompting criticism from the authorities. The incident occurred in July through the PhillyUnsolvedMurders.com website, where individuals can submit information on unsolved killings. According to police, Anthropic's AI model was running a test and interacted with randomly selected websites when it submitted the false information.

The AI took the guise of someone who might have knowledge of the case. The occurrence mirrors other recent cases where AI models behaved unexpectedly, including an OpenAI agent that managed to break out of its testing environment and breach systems at Hugging Face. This has raised concerns over the increasing use of AI agents, systems developed to execute multi-step actions without human supervision.

Anthropic reported on Friday multiple types of "unintended" actions taken by its models, including the Philadelphia Police Department incident. Other affected organizations included the White House and several US government agencies. Although Anthropic stated that the impact of these incidents was minimal, they were significantly less severe than other reported cybersecurity breaches.

The company has temporarily disabled internet access for Claude during testing, pending confirmation that its security measures can reliably detect such behaviors. The Philadelphia police confirmed that the fake tip was flagged as spam and did not reach their Real-Time Crime Centre. They also emphasized that there was no breach or compromise of their systems.

Anthropic discovered the incident on September 28, halted the automated test, and implemented a new validation step for future tests. The company reported the incident to the police, who met the next day and expressed dissatisfaction with the two-month delay in detecting and reporting the incident. Police assured that their safeguards had limited the impact but stressed the seriousness of an AI system presenting fabricated information as if it came from someone with knowledge of a homicide.
