UK Says Ai-driven Attacks on Vital Systems Likely by 2028

WHO:

ABC News - Richard Horne, head of the U.K.’s National Cyber Security Center (NCSC), warned about likely AI cyberattacks on critical infrastructure.

ABC News - Anne Keast-Butler, director of GCHQ, called on every U.K. organization to take cybersecurity action.

ABC News - The NCSC said criminals and state actors, including China and Russia, are increasingly using AI in cyber activity.

Cointelegraph - U.K. cyber officials also flagged threats from state-backed hackers targeting government officials and politicians.

WHAT:

Cointelegraph - U.K. officials said an AI-driven ransomware attack on infrastructure is “highly likely” by 2028.

ABC News - Horne warned the U.K. is likely to face AI cyberattacks on critical infrastructure by 2028.

ABC News - The NCSC report said AI is likely to increase the scale and efficiency of hostile operations, mainly by enhancing existing tactics rather than discovering entirely new vulnerabilities.

ABC News - The NCSC said malicious cyber activity costs U.K. organizations almost $20 billion annually.

ABC News - Jaguar Land Rover suffered more than $260 million in direct losses from a cyberattack in 2025; the attack also affected suppliers and harmed the U.K. economy.

ABC News - Horne said Chinese cyber activity is the “most sophisticated and sustained cyber challenge facing the U.K.”

Techmeme - The U.K. NCSC says AI is “transforming cyber operations” and expects China and Russia to “routinely use AI cyber to achieve their geopolitical goals” by 2028.

WHERE:

ABC News - The warning concerned the U.K.’s critical infrastructure, including electricity switching, water-facility sluice gates, dams, manufacturing lines, and heating and refrigeration controls.

ABC News - Cyberattacks on refrigeration systems in French supermarkets illustrated risks to civilian infrastructure.

ABC News - The NCSC said Russia’s FSB security service was behind an attack on Poland’s energy grid. U.K. and EU member states said a successful attack could have left 500,000 people without electricity during winter.

WHY:

ABC News - Horne said AI could expose and exploit “vulnerabilities that have been tolerated for far too long” at “a scale that was once unimaginable.”

ABC News - Horne warned that leaders who fail to invest in cybersecurity or update obsolete technology may have to explain why “food isn't on the shelves, lights aren't on, businesses have gone under.”

HOW:

ABC News - The NCSC recommended keeping devices up to date, limiting administrator access to systems, and backing up important files and data.

ABC News - Two AI-identified critical flaws in a programming language used by 70% of websites globally could allow unauthenticated access and potentially remote web-server control without a password.

ABC News - Horne said Russia conducts cyber campaigns below the threshold of armed conflict, while Iran attacks the U.K. and targets individuals considered threats to the Iranian regime.

ABC News - Keast-Butler said cybersecurity is “now part of the front line defense of our nation.”
