Federal agencies including the FBI, CISA, and NSA issued an urgent warning this week after Iran-linked hackers disrupted multiple U-S critical infrastructure organizations by targeting internet-exposed programmable logic controllers, particularly those made by Rockwell Automation. The attacks hit water systems, energy facilities, and government services, with hackers manipulating control system displays and project files in a campaign similar to previous operations by CyberAv3ngers, a group tied to Iran's Revolutionary Guard. Authorities are urging organizations to assume they're targets and proactively assess their operational technology environments for vulnerabilities.
