FBI: Iranian APT Targets Israeli-Made PLCs Used In Critical Industries

The report describes a joint U.S. and international cybersecurity advisory warning that IRGC‑affiliated actors known as Cyber Av3ngers have been exploiting default credentials and publicly exposed Unitronics Vision Series PLCs since November, defacing devices and causing at least one U.S. municipal water authority (Aliquippa, PA) to switch to manual operations; agencies recommend changing default passwords, removing Internet exposure, enabling MFA, and applying other mitigations to protect OT systems.
