Shield Your OT Environment: CISA/FBI Warns of Simple ICS/SCADA Exploits
Isolate OT from the Internet, enforce strong credentials, segment networks, and practice manual operations to prevent defacements and disruptions.
Unsophisticated cyber actors are targeting ICS/SCADA systems in Oil & Natural Gas sectors—conducting defacements, configuration interference, operational disruptions, and even risking physical damage—often by exploiting poor cyber hygiene and exposed assets. The CISA/FBI alert directs operators to a joint CISA–FBI–EPA–DOE fact sheet that recommends key mitigations, including disconnecting OT from the public internet, replacing default credentials with strong, unique passwords, securing and documenting remote access, segmenting IT and OT networks, and practicing manual operation of OT systems. Organizations should adopt these measures immediately to strengthen their critical infrastructure; contact us for assistance with implementation.
