US Critical Infrastructure Facing Iranian-Linked OT Threats
The US Cybersecurity and Infrastructure Security Agency has warned that Iranian-linked cyberthreat actors are actively exploiting vulnerable operational technology devices across US critical infrastructure. The threat actors are targeting programmable logic controllers, which has already led to disruptions and financial losses across multiple sectors.
The US Cybersecurity and Infrastructure Security Agency has issued a warning about Iranian-linked cyberthreat actors exploiting vulnerable operational technology devices. These devices are used in critical infrastructure sectors nationwide. The threat actors are targeting programmable logic controllers manufactured by Rockwell Automation/Allen-Bradley. The agency advises critical infrastructure owners to remove these devices from direct internet exposure and scan logs for suspicious traffic. They also recommend prioritizing basic cyber hygiene, including patching known vulnerabilities and enforcing multifactor authentication. The warning comes amid escalating tensions between the US and Iran. Iranian-linked groups have historically targeted industrial environments during periods of geopolitical tension. The US Cybersecurity and Infrastructure Security Agency is working with the FBI, NSA, and Department of Defense to address the issue. They urge organizations to take immediate action to secure their systems and prevent further disruptions.
