"CISA Urges Water Facilities to Secure Their Unitronics PLCs"

Following news that Iran-linked attackers had taken control of a Programmable Logic Controller (PLC) at a water system facility in Pennsylvania, a public alert was published by the Cybersecurity and Infrastructure Security Agency (CISA) urging other water authorities to secure their PLCs immediately. The cyber threat actors most likely gained access to the affected device, a Unitronics Vision Series PLC with a Human Machine Interface (HMI), by exploiting cybersecurity vulnerabilities such as poor password security and Internet exposure, according to CISA. This article continues to discuss CISA urging water facilities to secure their own Unitronics PLCs.
