He called for steps that enhance the cyber defense capabilities of all critical infrastructure operators.<\/p>\n<p>Mythos, developed by U.S. startup Anthropic, is highly adept at identifying system vulnerabilities, which has sparked concerns about its possible use in cyberattacks.<\/p>\n<p>Anthropic has not publicly released the AI model, and only a few companies and groups have access to it. Japan\u2019s three megabanks \u2014 MUFG Bank, Sumitomo Mitsui Banking and Mizuho Bank \u2014 are working to gain access.<\/p>\n<p>Hisashi Matsumoto, minister in charge of cybersecurity, also attended the meeting. \u201cWe hope to present a package of countermeasures as soon as possible,\u201d Matsumoto told reporters after the meeting.<\/p>\n<p>The proposal calls for countermeasures to be implemented first in the financial sector, citing not only national security considerations but also its vulnerability to attacks. It also outlines a plan to establish a working group comprising members including representatives of the information technology and online financial services industries, with the aim of building a framework for the public and private sectors to cooperate in defending against cyberattacks.<\/p>\n<p>Japan\u2019s Financial Services Agency on Thursday held the first meeting of a public-private working group to discuss and bolster measures against the risk posed by cutting-edge AI. It was attended by representatives from the government, the Bank of Japan, Japan Exchange Group, the three megabanks and Anthropic\u2019s Japan office.<\/p>\n<p>Also on Thursday, Takahiro Anno, leader of the Japanese opposition party Team Mirai, criticized the government for being slow in its handling of the cybersecurity threats posed by Mythos, saying, \u201cIt took time for the government to start moving.\u201d<\/p>\n<p>Anno pointed out that the British government called on financial institutions to take measures about a week after Anthropic released Mythos on April 7, while Takaichi only issued instructions on cybersecurity measures with Mythos in mind on Tuesday. \u201cI want to propose that the government adopt a system in which it can respond (to the latest developments),\u201d he said.<\/p>\n","protected":false},"excerpt":{"rendered":"Prime Minister Sanae Takaichi said Thursday that the government is rushing to take measures against the cybersecurity threats&hellip;\n","protected":false},"author":2,"featured_media":43630,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[176],"tags":[1695,8980,5417,177,179,9419,180,178,358,5027],"class_list":["post-43629","post","type-post","status-publish","format-standard","has-post-thumbnail","category-politics","tag-ai","tag-anthropic","tag-cybersecurity","tag-japans-politics","tag-japanese-politics","tag-mythos","tag-politics","tag-politics-of-japan","tag-sanae-takaichi","tag-startups"],"_links":{"self":[{"href":"https:\/\/www.europesays.com\/japan\/wp-json\/wp\/v2\/posts\/43629","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/japan\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/japan\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/japan\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/japan\/wp-json\/wp\/v2\/comments?post=43629"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/japan\/wp-json\/wp\/v2\/posts\/43629\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/japan\/wp-json\/wp\/v2\/media\/43630"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/japan\/wp-json\/wp\/v2\/media?parent=43629"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/japan\/wp-json\/wp\/v2\/categories?post=43629"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/japan\/wp-json\/wp\/v2\/tags?post=43629"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
