C0031 Unitronics Defacement Campaign

The Unitronics Defacement Campaign was a collection of intrusions across multiple sectors by the CyberAv3ngers, where threat actors engaged in a seemingly opportunistic and global targeting and defacement of Unitronics Vision Series Programmable Logic Controller (PLC) with Human-Machine Interface (HMI). The sectors that these PLCs can be commonly found in are water and wastewater, energy, food and beverage manufacturing, and healthcare. The most notable feature of this attack was the defacement of the PLCs' HMIs.
