Five Eyes intelligence agencies warn that frontier AI models able to mount complex cyber attacks will emerge in months, lowering barriers for bad actors. They urge treating cyber risk as a core business and societal responsibility, citing the US block on foreign use of Anthropic’s Fable and warning of other advanced models in development.

• Five Eyes intelligence agencies warn AI models capable of devastating cyber attacks on governments and businesses will emerge within months, drastically lowering the barrier for bad actors.
• The US has already barred foreign nationals from using Anthropic's Fable and Mythos models, citing national security concerns over their ability to find and exploit security flaws.
• Australia has signed a non-binding deal with Anthropic to share AI progress, favoring a "light-touch" regulatory approach to capture economic benefits despite the risks.
• Experts warn other states or companies, including China, could soon develop similar or more advanced offensive AI systems.
