ECB Summons Banks to Emergency Meeting Over Cybersecurity Flaws Exposed by Claude Mythos

Finextra / Bloomberg·high signal

The European Central Bank is convening lenders this week to address cybersecurity vulnerabilities that Anthropic's Claude Mythos Preview has exposed across banking IT systems. ECB Executive Board member Frank Elderson warned that patches can now be reverse-engineered to find the underlying vulnerability in 30 minutes rather than weeks. European banks feel particularly exposed because Anthropic has restricted Mythos access to mostly US organizations under Project Glasswing, creating a transatlantic cybersecurity information asymmetry.
