Cyber Av3ngers Hacktivist Group Targeting Israel-Made OT Devices

Dragos Threat Intelligence documents hacktivist activity by the Cyber Av3ngers targeting Israel-related systems and opportunistically scanning for and exploiting internet-accessible Unitronics PLCs; at least one U.S. municipal water authority PLC was accessed and its menu defaced. The report references a CISA advisory, details likely attacker techniques (default credentials, probing TCP 20256/PCOM), notes limited downstream impact observed so far, and provides mitigation recommendations including changing default passwords, securing remote access with MFA/VPNs, network segmentation, and updating devices.
