Japan's megabanks seek OpenAI model to harden cyber defences
Three Japanese megabanks plan to use OpenAI's new model and Anthropic's Claude Mythos to reinforce system security against AI-linked cyber threats.
- Japan's three largest banks, MUFG, Sumitomo Mitsui, and Mizuho, are set to use a new OpenAI model to strengthen their cybersecurity defences.
- The primary application of the AI will be to identify system vulnerabilities and protect against cyberattacks.
- The banks are also seeking access to a similar AI model from the US start-up Anthropic, planning to use both to enhance security.
- This move is a response to urging from Japanese financial regulators to step up measures against AI-related cyber threats.
Japan’s three megabanks are expected to gain access to a new artificial intelligence model from OpenAI, the US company behind the generative AI chatbot ChatGPT, informed sources said on Thursday (May 28).
MUFG Bank, Sumitomo Mitsui Banking Corp. and Mizuho Bank plan to apply the model to strengthen their defences against cyberattacks, according to the sources.
The new OpenAI model is believed to have capabilities comparable to Claude Mythos, an AI model developed by US start-up Anthropic that is regarded as highly effective at identifying system vulnerabilities.
The three banks are also seeking access to Mythos, aiming to use both advanced models to improve the security of their systems.
The move comes as Japan’s Financial Services Agency and the Bank of Japan have urged domestic financial institutions to step up measures against AI-related threats, amid concerns that new AI models could be used to launch cyberattacks.
