Hostile actors are highly likely to target critical infrastructure with artificial intelligence-powered ransomware within two years, according to an assessment released by the British National Cyber Security Centre.
The agency's Annual Review 2026, titled "The State of the Cyber Nation," notes that automated tools will dramatically accelerate the speed, efficiency and scale at which attackers locate network weaknesses, launch phishing campaigns and deploy malicious code against public utilities and private enterprises.
Dr. Richard Horne, chief executive officer of the NCSC, stated that the risk stems from organizations relying on outdated security setups and cheap technology rather than AI inventing entirely novel attack methods.
Horne emphasized that vulnerabilities left unpatched for years can now be uncovered at an unprecedented pace. The agency urged operators to disconnect unnecessary systems from the public internet, adopt established baseline standards such as Cyber Essentials and increase capital expenditure on resilience to avert service disruptions across vital supply chains.
