Iranian Hackers Exploit PLCs in Attack on Water Authority in U.S.

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) uncovered that it’s responding to a cyber attack that concerned the active exploitation of Unitronics programmable logic controllers (PLCs) to focus on the Municipal H2o Authority of Aliquippa in western Pennsylvania.

The attack has been attributed to an Iranian-backed hacktivist collective regarded as Cyber Av3ngers.

“Cyber threat actors are focusing on PLCs related with [Water and Wastewater Systems] amenities, such as an determined Unitronics PLC, at a U.S. water facility,” the company said.

“In response, the influenced municipality’s h2o authority immediately took the process offline and switched to handbook operations—there is no regarded risk to the municipality’s consuming h2o or water provide.”

According to information reports quoted by the Water Data Sharing & Evaluation Heart (WaterISAC), CyberAv3ngers is alleged to have seized management of the booster station that displays and regulates strain for Raccoon and Potter Townships.

With PLCs being utilised in the WWS sector to monitor different stages and processes of water and wastewater cure, disruptive assaults making an attempt to compromise the integrity of these types of critical procedures can have adverse impacts, preventing WWS amenities from delivering entry to cleanse, potable drinking water.

To mitigate this kind of assaults, CISA is recommending that organizations alter the Unitronics PLC default password, enforce multi-aspect authentication (MFA), disconnect the PLC from the internet, back up the logic and configurations on any Unitronics PLCs to allow speedy recovery, and utilize newest updates.

Cyber Av3ngers has a background of concentrating on the critical infrastructure sector, professing to have infiltrated as several as 10 water treatment stations in Israel. Very last month, the team also claimed obligation for a main cyber assault on Orpak Techniques, a prominent supplier of fuel station solutions in the country.
