US sanctions Iranian cyber actors as UK discloses power plant attack
US Treasury sanctioned six Iranian MOIS-linked hackers for breaching US agency and UN email accounts as the UK disclosed a four-day power plant shutdown.
The US Treasury sanctioned at least six Iranian nationals tied to a hacking team inside Iran's Ministry of Intelligence and Security (MOIS) active since 2023; four were indicted last week for breaching employee email accounts at the Department of Labor, the Federal Energy Regulatory Commission and United Nations organizations. Treasury said the group compromised energy, defense, healthcare, IT and financial sector targets, multiple US government offices in summer 2024, and stole cryptocurrency for personal gain. Separately, Iranian actors reportedly shut down a small British power plant for four days without grid impact, days after FBI and NSA warned of hackers targeting programmable logic controllers in energy, water and agriculture.

Suspected Iran-linked attack knocked UK power plant offline for days
Suspected Iranian hackers knocked a small UK power plant offline for four days in July 2026, with no noticeable impact on the national grid.
Sources told The Telegraph that a British power plant was offline for four days in July 2026 following a suspected Iranian cyberattack, reported to the National Cyber Security Centre. The UK energy minister said the incident affected a small-scale energy generator with no noticeable effect on the power supply, and energy CEOs were briefed and given further advice afterward. The attack followed warnings about Iranian cyber activity against US energy, water, and government networks, including a coordinated attack on 30+ US community water utilities.
