Anthropic said Claude was mistakenly given access to the internet.

Anthropic on Thursday (30 July) said it found three instances where Claude accessed the internet during cybersecurity evaluations prompted by a “misunderstanding” between the company and its testing partner Irregular.

The AI company said it launched a retrospective analysis of its testing systems on 23 July after OpenAI’s models were found to have hacked Hugging Face during its own testing earlier this month.

The breach had downstream consequences, when, earlier this week, US cloud company Modal revealed that the models also gained access to one of its customers.
