History

Historical Context

In May 2017 the WannaCry ransomware, powered by the NSA-leaked EternalBlue exploit, infected more than 230,000 Windows computers across over 150 countries, crippling hospitals and firms and prompting calls for sovereign cyber defenses. Following that shock, the EU agency ENISA in 2024 announced a partnership with Anthropic to test the Claude Mythos AI model for autonomous vulnerability detection, aiming to reduce reliance on external tools.
