The PLC bore the brand of the producer Unitronics. An indication above it learn “Main PLC.”
WWS services within the cross hairs
The Cybersecurity and Infrastructure Safety Administration on Tuesday printed an advisory that warned of latest assaults compromising Unitronics PLCs utilized in Water and Wastewater Methods, which are sometimes abbreviated as WWSes. Though the discover didn’t determine any services by title, the account of 1 hack was virtually equivalent to the one which occurred contained in the Aliquippa facility.
“Cyber menace actors are concentrating on PLCs related to WWS services, together with an recognized Unitronics PLC, at a US water facility,” CISA officers wrote. “In response, the affected municipality’s water authority instantly took the system offline and switched to guide operations—there isn’t any recognized threat to the municipality’s consuming water or water provide.”
Water Authority officers instructed reporters the hacked PLC regulates stress to elevated areas and was housed in what’s often known as a booster station that served Raccoon and Potter.

A second hack hitting the North Texas Municipal Water District got here to mild on Monday after a ransomware group tracked as DAIXIN added the district, abbreviated as NTMWD, to its leak web site. The put up mentioned the group has stolen delicate information contained in 33,844 recordsdata.
