Iranian hackers reportedly shut down a British power plant for four days in an unprecedented cyberattack. This incident marks the first time Iran-linked hackers have successfully disrupted a UK energy facility. The affected facility was described as a "small-scale energy generator." Officials stated that the attack posed no risk to the wider energy system and did not result in reported outages. This cyberattack coincides with alleged attacks on US water infrastructure affecting multiple states. British officials have withheld details about the targeted facility due to security concerns. The UK government has since briefed power company executives and advised businesses on next steps. This escalation is seen as a response to the UK's decision to allow US "defensive operations" against Iran from British bases. The US operations are aimed at Iranian missile facilities that threaten British personnel and allies. In June, an Iran-linked group claimed responsibility for a cyber intrusion on California water facilities in retaliation for alleged US strikes. This group also claimed to have obtained sensitive data from the former Israeli army chief of staff's phone.
