Curated summary with source attribution

Threat Risk: High
Victim: US Water and Wastewater Sector (WWS)
Incident: Cyberattacks targeting PLCs in water systems across seven US states.
Impact: Loss of system pressure, flooding, and operator lockout from critical OT controls.
Attacker: Iran-linked threat actors
Analysis: Threat actors are targeting internet-exposed Rockwell Automation and Allen-Bradley PLCs to disrupt water operations. By altering passwords and IP addresses, the attackers effectively locked out legitimate operators and modified project files. This activity demonstrates a targeted effort to destabilize critical utility OT environments.
Recommendations: Remove all publicly exposed PLCs and OT devices from the internet immediately.; Implement strong identity and access management for all remote OT connections.; Develop and test manual operation protocols to ensure facility resilience during cyber incidents.
