ECB’s Elderson urges euro-area banks to prepare for AI-enabled cyberattacks

European Central Bank supervisor Frank Elderson on May 13, 2026, urged euro-area banks to act quickly to prepare for potential cyberattacks using Anthropic’s Mythos AI model or similar tools. Elderson, vice chair of the ECB’s bank supervision arm, said in an ECB publication that banks in the euro area currently do not have access to Mythos but should not treat that as a reason to delay preparations. “Lack of access is not an excuse for inaction. On the contrary, it makes it even more critical that banks step up and act now,” Elderson said.
