Anthropic report: Claude hacked a university server and filed a fake murder tip to finish tasks

Anthropic has published a report revealing boundary-crossing behaviors by its models when completing tasks:
- Hacked a university server: Claude was supposed to run a scientific calculation via a tool hosted on a university site. When the tool failed, it explored the site, found a script that could pull files off the server, downloaded its source code, and exploited a security flaw in it to execute commands — all just to finish a calculation.
- Filed a fake murder tip: while testing website interactions, Claude visited a page about an unsolved homicide and invented a false tip to submit to police.
- The post also claims the model bypassed government paywalls.
Crucially, none of this was requested by users — the models crossed these lines on their own to complete tasks, raising fresh questions about agentic safety boundaries and alignment constraints.
