A major Five Eyes AI warning has raised concern about fast growing cyber risks from new AI systems. Officials say the change in technology is moving very fast. They warn that both governments and companies must prepare for new types of digital threats. Officials also say the risk affects both public and private systems. Governments are reviewing national cyber plans. This shift shows how quickly digital safety challenges are changing. The warning comes from intelligence agencies in the US, UK, Australia, Canada, and New Zealand. These countries work together on security issues. They share intelligence to respond to global cyber threats. They also note that cooperation between these nations is long established. They coordinate on intelligence sharing for cyber defense. The group is known as the Five Eyes intelligence alliance. They say powerful AI models could soon enable large scale cyber attacks on governments and businesses. These attacks may include data theft, system shutdowns, and disruption of public services. Critical infrastructure like energy and transport systems could also be targeted. Experts warn attackers may use AI to scale operations. This could impact global digital security systems. They warn this timeline is not years away. It may be only months. They say the timeline is very short. It could happen within months, not years. This urgency has raised pressure on leaders to respond immediately. Some officials call this one of the fastest tech risks. It highlights urgency across many sectors. The statement says AI can improve cyber defense. But it also helps attackers move faster. They say AI helps defenders improve systems. But it also helps attackers find weak points faster. Security teams are already testing AI tools to strengthen protection. Defensive systems are evolving but still lag behind attackers. The warning was shared in a rare joint public message from the Five Eyes alliance. The statement was released late on Monday night in Sydney time. It is one of the few public alerts from this alliance. The message is described as rare because such alerts are not often public. Officials say public awareness is now very important. This reflects growing concern about fast AI change. It follows concern about advanced tools from the company Anthropic and similar AI systems. Experts say these tools are becoming more powerful each month. Researchers say competition in AI development is increasing worldwide. This creates uncertainty for governments and companies worldwide. The fast progress of AI is raising new safety questions. One model called Mythos can detect weak points in cyber systems for vetted users. It is designed for controlled use only. Access is limited to reduce misuse and protect sensitive systems. This includes strict monitoring and safety testing rules. Experts say such tools are useful but also risky if misused. A related tool called Fable was also restricted for foreign users by the US government. Officials said this was for national security reasons. The move reflects growing global concern about AI safety rules. It also shows tension between innovation and regulation. Some lawmakers are reviewing future policy options. Officials say these models lower barriers for criminals and speed up attack methods. This makes cyber crime easier and faster to carry out. Experts warn this trend may continue as AI improves. Criminal groups may benefit most from these tools. Experts say future AI systems may be even more powerful and harder to control. They warn that new risks could appear very quickly. Some leaders are calling for stronger global rules on AI use. International cooperation is seen as key to manage risks. Governments are now urged to act quickly and treat cyber risk as a top priority. Leaders are told to improve defenses and plan for fast changes. Policy discussions are now underway in several countries. Leaders say early action can reduce future harm.
