FRANKFURT, April 21 (Reuters) – Banking authorities must prevent the misuse of ​Anthropic’s Mythos, ‌its most advanced AI model to date, which opens the door to ‌new ​and sophisticated ⁠cyber risks, Bundesbank ⁠President Joachim Nagel said on Tuesday.

“Mythos is an AI model that appears capable ​of quickly identifying and exploiting security ⁠vulnerabilities in ⁠financial institutions’ software,” ​Nagel said in a ​speech.

“However, this AI model seems to be ‌a double-edged sword, since it could be used not only ⁠to improve digital security systems, but also to leverage ⁠their vulnerabilities ‌for malicious purposes,” ⁠he added.

He ​added ‌that all relevant institutions ​should ⁠have access to such technology to avoid competitive distortions.
