Anthropic's Claude Mythos Discovers Thousands of Zero-Day Vulnerabilities, Prompting Emergency Meeting Among Bank CEOs
Anthropic's Claude Mythos Preview has identified thousands of zero-day vulnerabilities in major operating systems and web browsers, leading to a meeting between the Federal Reserve chair and Treasury secretary with bank CEOs. The company warns that there is a six-to-twelve month window to patch these vulnerabilities before adversaries can replicate its capability. In controlled tests, Mythos outperformed most human experts in finding and exploiting software flaws, including long-standing bugs. Mozilla's recent Firefox update addressed 271 vulnerabilities identified by Mythos. The model's ability to drastically reduce the cost of finding vulnerabilities poses significant challenges for the cybersecurity industry, reshaping the dynamics between attackers and defenders.
