Japan will set up a task force to address cybersecurity risks in its financial system.
Japan will establish a cybersecurity task force focused on risks from Anthropic's Mythos AI model.
KEY POINTS
Anthropic's Mythos AI preview identified thousands of major vulnerabilities in all major operating systems and browsers.
Experts warn Mythos can discover and exploit unknown vulnerabilities faster than companies can patch them.
No breaches linked to Mythos have been reported yet, but regulators globally are warning banks to strengthen defenses.
TOKYO, April 24 (Reuters) - Japan will set up a task force to address cybersecurity risks in its financial system following concerns about potential vulnerabilities linked to Anthropic's Mythos AI model, Finance Minister Satsuki Katayama said on Friday.

"I told the meeting that this is a crisis that is already at hand, and similar concerns were also voiced by the financial industry," she said.
Concerns have intensified after Anthropic said a preview of Mythos uncovered "thousands" of major vulnerabilities across every major operating system and web browser, raising fears about the resilience of traditional software security.
Experts warn the model can identify and exploit previously unknown vulnerabilities faster than companies can repair them, accelerating cyberattacks in sectors such as banking that rely on complex, interconnected and often decades-old technology.
Regulators elsewhere in Asia, Europe and the United States have warned banks to review defences and preparedness. To date, there have been no reported breaches related to the model.
Katayama said the financial system's high level of interconnectedness and real-time operations mean that problems can spread more rapidly than in other sectors.
"Because of this, a cyberattack can immediately spill over into market disruptions and undermine confidence."
