The startup Cathedral, founded by former employees of the US Department of Government Effectiveness (DOGE), which was overseen by businessman Elon Musk, hacked the internal systems of artificial intelligence developer Anthropic in less than 12 hours, the Washington Post (WP) reported, citing a report from the startup. Cathedral researchers used artificial intelligence agents and vulnerabilities in third-party software that Anthropic used for administrative and sales tasks. As a result, they discovered ways to access meeting recordings, internal correspondence and information about company employees' salaries.
