A small-scale power generator in the United Kingdom was reportedly shut down for four days in July after a cyberattack attributed by The Telegraph to hackers linked to Iran. The U.K. government confirmed that an incident affected a small energy generator but declined to identify the facility or assign blame. Officials emphasized that the event did not threaten the broader energy system, describing the country’s energy infrastructure as highly resilient.
The incident reportedly occurred around the same time that U.S. authorities, including the Federal Bureau of Investigation, warned that malicious Iranian cyber actors were targeting water facilities in at least seven states. The Cybersecurity and Infrastructure Security Agency, FBI, Environmental Protection Agency and other agencies attributed those attacks to Iran.
In response to the U.K. incident, the Department of Energy Security and Net Zero briefed energy-sector chief executives, advised companies on additional measures and began updating cybersecurity regulations. The report places the event within a wider period of heightened cyber risk following the launch of a U.S.-Israel war against Iran on February 28. The article also cites an August 18 U.S. Justice Department indictment charging 17 Iranians with an extensive cyber-theft campaign allegedly conducted on behalf of the Islamic Revolutionary Guard Corps and other Iranian entities.
Iran has also experienced significant cyberattacks. In June, blockchain analytics company Elliptic reported that Nobitex, Iran’s largest cryptocurrency exchange, lost more than $90 million. The funds were transferred to wallets containing anti-government messages referencing the IRGC, suggesting a politically motivated attack. The pro-Israel hacking group Gonjeshke Darande, or “Predatory Sparrow,” claimed responsibility.

Iranian-linked hackers reportedly shut down a small-scale British power generator for four days, marking what may be the first publicly known instance of Iran-linked cyber actors successfully disrupting a power-generation facility in the United Kingdom. The incident, which occurred before being reported in July, was disclosed to the National Cyber Security Centre (NCSC), the public-facing cybersecurity arm of GCHQ. The generator and power plant were not identified.
British officials said the attack did not threaten the country’s wider electricity supply, but the incident nevertheless alarmed the energy industry and prompted renewed warnings about the growing threat posed by Iran-linked cyber groups. Earlier in the year, the NCSC had advised companies to prepare for potential attacks amid escalating tensions involving Iran, the United States and its allies.
The report places the British incident within a broader pattern of alleged cyberattacks against critical infrastructure. Attacks targeting water infrastructure have affected at least 12 US states, while Minnesota officials have accused Iran of causing brief automated shutdowns and issuing boil-water notices. The UK government has also warned that attacks against domestic infrastructure remain a serious risk, particularly as artificial intelligence may make cyberattacks faster and easier to launch.
Despite the disruption, British authorities emphasized that the national energy system remains resilient. A government spokesperson said officials were working closely with the energy sector to protect infrastructure and maintain high security standards. The incident has nonetheless intensified calls for critical-infrastructure operators to strengthen defenses against state-linked cyber threats and prepare for attacks capable of causing localized operational outages.

The article reports that hackers allegedly linked to the Iranian government shut down a small British power generator for four days in what may be the United Kingdom’s first cyberattack against an energy facility. The incident occurred the previous month and coincided with a series of cyberattacks against US water infrastructure that affected 12 states. Although the targeted generator was small and the attack did not threaten the wider UK electricity grid or cause power outages, Energy Minister Michael Shanks said both the facility and the government treated the incident seriously.
The UK has thousands of small-scale power-generation sites connected to its electricity grid. Many are gas-fired generators that operate only for limited periods each week, potentially creating a broad and diverse attack surface. The Telegraph reported that the incident may have been designed as a demonstration of capability, showing that hackers associated with Iran’s Islamic Revolutionary Guard Corps could penetrate British energy systems and disrupt infrastructure.
The National Cyber Security Centre has warned of an increasing pattern of disruptive cyber activity by both state and non-state actors targeting UK organisations. It is urging organisations to review their cybersecurity measures and follow official guidance. Shanks said the government’s energy-sector cybersecurity strategy is intended to strengthen protections, while a broader energy resilience strategy planned for later in 2026 will address a wider range of risks. The incident caused no reported loss of power, but officials view it as a significant warning about the vulnerability of smaller energy facilities and the potential for future attacks on critical infrastructure.
