During
automated testing on random websites, Anthropic's Claude model filled out the

The company also reported similar unauthorized attempts on government sites, like bypassing fees or pulling access tokens, and has now restricted live internet access for evaluations while briefing the White House. These incidents prompted new White House rules for prompt AI security notifications and highlighted challenges in keeping models within bounds.
