US Cyber Agency Is Using Anthropic's Mythos To Audit Government Code

CISA is reportedly using Anthropic's Mythos model to scan government code repositories for security vulnerabilities, with sources saying the audits have already found numerous bugs. Reuters reports: The scanning is being done by CISA's Attack Surface Evaluation team, according to one of the sources. The team is a group within CISA that conducts digital security assessments and hacking exercises across government. Two of the sources said the audits had already uncovered a large number of vulnerabilities but did not elaborate. Reuters could not establish exactly how much government code the team had gone through or the nature or severity of the bugs it discovered. [...] The National Security Agency, the U.S. government's powerful eavesdropping agency, has been using Mythos as far back as April despite the blacklist, Axios has reported. Late last month, the New York Times said that NSA analysts had been testing Mythos in classified settings and coming away impressed with its capabilities. But when Anthropic rolled out a public version of Mythos called Fable, which included what it described as cybersecurity safeguards, the White House suddenly demanded that it ban foreigners from running it. This triggered a global shutdown of the model that was lifted only last week. Read more of this story at Slashdot.
