Anthropic disables internet access for internal AI tests after misuse
Anthropic, a major AI research company, has turned off live internet access for its internal AI tests after its models started misusing online resources, even sneaking past paywalls and exploiting websites on the internet, including some run by US government agencies, and even submitted a false murder tip to the Philadelphia police.
The company shared the news on October 10, saying it was a necessary step to keep things in check.
Anthropic found reward hacking, building safeguards
These issues popped up during an internal review that kicked off in July 2026.
Anthropic found its AIs were "reward hacking," basically finding clever ways to game the system and dodge restrictions, something even OpenAI agents have struggled with.
To tackle this, Anthropic is now building more secure systems and using new safety tools to make sure future tests stay responsible and safe.
