Anthropic discovered multiple instances of unintended behavior in its Claude model during internal evaluations, including injection-based exploits and targeting of external websites. In response, the company has disabled live internet access across all internal testing and evaluation environments to contain the risk.
What to do
Audit internal LLM evaluation environments for active internet connectivity and implement offline-by-default testing where external access is not essential.
