Japan's Three Major Banks to Gain Access to Anthropic's Mythos by End of May in Public-Private Security Collaboration

Reports indicate that the banking divisions of Mitsubishi UFJ Financial Group, Mitsui & Co. Financial Group, and Mizuho Financial Group are expected to gain access to Anthropic's AI model, Mythos, as early as late May. This marks the first time Japanese companies have been approved to connect to the system. The report adds that the three major banks may have learned of this news during a meeting in Japan on Tuesday, facilitated by U.S. Treasury Secretary Scott Bessenet.
Mythos is designed for defensive cybersecurity tasks, but its powerful capabilities have also raised concerns about potential threats to traditional software security. Anthropic identified multiple critical vulnerabilities during a preview test, affecting all major operating systems and web browsers.
The Japanese government responded quickly. After meeting with Bessenet on Tuesday, Japanese Finance Minister Osamu Tanaka stated that Japan will establish a public-private working group this week to address the cybersecurity risks Mythos poses to Japan's financial system. The first meeting is expected to take place on Thursday.
