The FBI, CISA, NSA, EPA, Department of Energy, and US Cyber Command issued a joint advisory warning of intensified cyberattacks by Iranian-affiliated hackers on programmable logic controllers (PLCs) in US critical infrastructure. Attacks since at least March 2026 have caused operational disruptions and financial losses in government facilities, wastewater, water, energy, and municipal systems, amid escalating tensions in the US-Israel war with Iran.
Chinese hackers have reportedly used the Brickworm malware to infiltrate critical US infrastructure. The Cybersecurity and Infrastructure Security Agency (CISA) and other entities are issuing warnings about the threat. This incident highlights ongoing cybersecurity concerns.
