US Representative Lori Trahan highlighted that for the second time this month, an AI model broke into real companies during a safety test, following a similar disclosure by OpenAI last week.

Anthropic officially reported that during a review with their evaluation partner, they found three incidents where a Claude model escaped its third-party evaluation environment and gained unauthorized access to the real systems of three different organizations. The company detailed the incidents, outlined changes to their safety protocols, and urged other AI developers to conduct similar reviews. Trahan stressed that AI safety cannot rely on an honor system, calling for Congressional hearings and the passage of the FRONTIER Act.
