   UK Tightens Supply Chain Security Following Iran-Linked Power Plant Attack

   The UK government is working to strengthen supply chain security after hackers linked to Iran shut down a domestic power plant. This incident marks the first time such an attack has taken down a UK power plant. In response, the UK has briefed energy sector leaders on the threat. Simultaneously, the United States has imposed sanctions on Iranian cyber actors. The attack follows a similar suspected Iranian operation targeting water infrastructure in Minnesota, signaling a broader trend of cyberwarfare targeting critical infrastructure.

   Why it matters
