UK’s small power plants face continued cyber risk after Iran-linked hack

Government measures to improve resilience are not due until 2030 and July’s hack has not altered this timeline

Hundreds of Britain’s smallest power plants could remain at a higher risk to state-sponsored cyber-attacks until the 2030s despite a successful Iran-linked hack last month, it has emerged.

Officials this week briefed energy bosses on the breach, which is understood to have shut an unnamed small gas power plant for four days last month, and put the industry on alert over the growing cyber threat facing energy infrastructure.
