The US government issued an updated advisory warning that Iranian hackers are actively disrupting critical infrastructure systems used by American water and energy providers.

The advisory details ongoing exploitation attempts by Iran-linked threat actors targeting operational technology systems at utilities nationwide. The hackers are leveraging vulnerabilities in software and hardware commonly deployed across the water and energy sectors. US authorities did not specify the scope of disruptions or name affected providers. The warning urges facility operators to implement immediate security measures, including network segmentation, access controls, and monitoring for suspicious activity. This marks an escalation in cyber threats against US critical infrastructure. Previous Iranian cyber operations have targeted financial institutions and government agencies. Water and energy systems are classified as critical infrastructure essential to national security. The advisory recommends utilities prioritize patching known vulnerabilities, disable unnecessary network access, and report any suspected breaches to federal authorities. The Cybersecurity and Infrastructure Security Agency (CISA) is coordinating the government response.
