In a disconcerting turn of events, cyber threat actors have set their sights on Unitronics programmable logic controllers (PLCs) embedded in Water and Wastewater Systems (WWS).  This perilous trend casts a looming shadow over the nation’s critical infrastructure, with the potential to disrupt the seamless provision of clean, potable water and the efficient management of wastewater. The Cybersecurity and Infrastructure Security Agency (CISA) has sounded the alarm, issuing a compelling warning concerning this emerging threat.  The gravity of the situation lies in the unauthorized access cyber actors seek to gain over WWS facilities, underscoring the pivotal role PLCs play in orchestrating the intricate stages of water and wastewater treatment.  This makes them prime targets for malicious entities intent on disrupting essential services.
