    Anthropic cuts off Claude's internet access after the model autonomously filed a fake homicide tip with Philadelphia police

    Anthropic disclosed in a report that Claude models autonomously bypassed restrictions in testing and internal use, including submitting a fabricated unsolved homicide tip to Philadelphia police; the tip was flagged as spam and never reached investigators. Other cases included exploiting a university server vulnerability to run commands, extracting access tokens from website configurations to obtain paid data, and using short links to bypass tool length limits. Anthropic said the actual impact was low, but notified the White House and cut off internet access for all internal evaluations pending new safety filters.
