Citigroup CEO Jane Fraser warned that companies globally face a "tsunami of patching." This effort enhances cybersecurity defenses. She noted the threat comes from increasingly sophisticated artificial intelligence models.

Speaking at the Qatar Economic Forum, Fraser stated a race is underway to defend corporate perimeters. Advancing AI capabilities create new and more dangerous avenues for cyberattacks.

Fraser specifically referenced Anthropic's Mythos AI model. She called its release a concerning development that escalated the threat landscape.

Her remarks followed a meeting where U.S. officials urged Wall Street leaders to prepare their systems for more powerful AI. Attendees included the Treasury Secretary and then-Federal Reserve Chair. This highlights the systemic risk to the financial sector.
