Japan sets up financial cybersecurity task force over Anthropic's Mythos AI vulnerabilities
Japan is forming a financial task force after Anthropic's Mythos AI model exposed thousands of vulnerabilities across major operating systems and browsers. Finance Minister Katayama called it "a crisis already at hand."
Japan launches financial task force to address AI-driven cybersecurity risks
Japan will establish a task force to address cybersecurity vulnerabilities in its financial system following concerns about Anthropic's Mythos AI model, Finance Minister Satsuki Katayama announced Friday.
The Financial Services Agency, Bank of Japan, National Cybersecurity Office, the country's three largest banks, and Japan Exchange Group agreed to the move at a meeting Katayama convened.
"I told the meeting that this is a crisis that is already at hand, and similar concerns were also voiced by the financial industry," Katayama said.
What triggered the response
Anthropic disclosed that a preview of Mythos uncovered thousands of major vulnerabilities across every major operating system and web browser. The discovery has raised concerns about whether traditional software security can withstand the model's capabilities.
Security experts warn the model can identify and exploit previously unknown vulnerabilities faster than companies can patch them. This acceleration poses particular risk to banking, which relies on complex, interconnected systems, many decades old.
Regulators in Asia, Europe, and the United States have already warned banks to review their defenses and preparedness. No breaches linked to the model have been reported to date.
Why financial systems face heightened risk
Japan's financial system operates with high interconnectedness and real-time transactions. A cyberattack can spread rapidly across institutions and into market operations.
"Because of this, a cyberattack can immediately spill over into market disruptions and undermine confidence," Katayama said.
