U.S. Warns Iran-Linked Hackers Target Rockwell PLCs

U.S. agencies have issued a warning that Iran-linked hackers are actively targeting internet-connected programmable logic controllers (PLCs) in critical infrastructure sectors. The FBI and CISA highlighted these cyber threats in a joint advisory. These attackers focus on Rockwell/Allen-Bradley PLCs, aiming to disrupt essential services such as water, energy, and government systems through manipulation of data on HMI and SCADA displays. Authorities identified a group called CyberAv3ngers as potentially responsible, exploiting these systems since November 2023.

Organizations are urged to assess their exposure and implement security measures, including disconnecting PLCs from the internet where feasible. Enhanced monitoring and cooperation with federal agencies are also recommended to mitigate risks. The U.S. warns Iranian hackers have escalated their attacks, presumably due to ongoing tensions with the United States and Israel.
