KYODO reported a senior government official said Japan is considering deploying
cutting-edge AI systems under its 'proactive cyber defense' policy to counter
attack risks from advanced models such as ANTHROPIC's Claude MYTHOS. National
cybersecurity director Yoichi Iida said using advanced AI is "unavoidable" and
warned the time from discovering a vulnerability to exploiting it could
plausibly shrink to 1% or 0.1% of previous lengths. The cabinet led by Prime
Minister TAKAICHI decided in March that, from Oct. 1, the government may take
proactive cyber-defense measures to preempt severe attacks on critical
infrastructure, economic activity and livelihoods.
