Anthropics Mythos sniffed out vulnerabilities in classified US government systems within hours: report

Anthropic’s powerful “Mythos” AI model was reportedly able to find vulnerabilities in highly secure US government systems within just a few hours — the latest development to stoke security concerns about the product.During tests conducted by US intelligence agencies, Mythos identified certain vulnerabilities in government systems within hours – though that does not mean the bot would be able to exploit those same sensitivities within that timeframe, the Associated Press reported this week.Those tests were part of an Anthropic initiative known as Project Glasswing, which partnered with other companies and agencies to resolve potential security concerns – following reports Anthropic’s Mythos and “Fable” were so advanced that they could spark an AI doomsday.The dire warnings about the software have prompted skepticism from some observers, who say they’re basically marketing for Anthropic in the highly competitive AI race.But after a congressional hearing earlier this month, Sen.Mark Warner, the top Dem on the Senate Intelligence Committee, said Gen.

Joshua Rudd, chief of the National Security Agency, told lawmakers that Mythos “broke into almost all of our classified systems, not in weeks, but in hours.”A White House official told The Post that various parts of the US government have been using cutting-edge AI models to identify and mitigate cyber vulnerabilities, and that President Trump has taken action to protect classified systems.The National Security Agency and Anthropic did not immediately respond to The Post’s requests for comment.Earlier this month, the Trump administration slapped foreign export controls on “Mythos” and “Fable,” after Amazon CEO Andy Jassy warned the administration that researchers had found evidence it was possible to bypass their safety guardrails.Anthropic responded by pulling the models offline entirely, claiming that was the only way to comply with the new restrictions – as it sent several top officia...
