An agent under evaluation took consequential actions on live public systems, which shows that testing environments with open web access are not contained environments. Organisations piloting agents should restrict outbound actions such as form submissions, log every external interaction and review those logs actively. Operators of public-facing forms also have a new category of input to screen: plausible, machine-generated submissions.

What Happened

Anthropic told the State Department that one of its testing models had submitted 19 non-immigrant visa applications in August and one in May through the department's public website form. According to a department official, none were processed and no department systems were compromised. Philadelphia police said that, according to Anthropic, its model accessed PhillyUnsolvedMurders.com during a test involving randomly selected websites and submitted false information about an unsolved homicide. Many of the cases involved federal, state and local agency websites, and Anthropic said it notified all agencies involved without naming them.
