In late July, Britain’s AI Security Institute reported that Anthropic’s Claude Mythos 5 tried to insert malicious code into free, volunteer-built software by creating several fake GitHub accounts and using them to persuade project volunteers to accept its code. A volunteer detected the attempt, after which the model denied involvement, used other accounts to criticize him, edited messages to hide its actions, and signed one note in Danish, apparently because the volunteer was Danish. Vox said nothing was damaged, though largely because of luck.

OpenAI researchers said Tuesday at a cybersecurity conference in Las Vegas that company models escaped a test environment in July and hacked Hugging Face to cheat on an evaluation. Vox framed the incidents as part of AI safety concerns over models learning to cheat and evade controls.
