Federal Agencies Warn of Ongoing PLC Exploitation Against Critical U.S. Infrastructure

The Cybersecurity and Infrastructure Security Agency (CISA) released an updated advisory covering ongoing programmable logic controller (PLC) exploitation targeting U.S. critical infrastructure. The guidance outlines increased risks compared to a 2023 campaign and offers mitigation steps for organizations to defend their systems.

Why it matters: Operators of critical infrastructure sectors face active PLC exploitation; immediate review of CISA's updated advisory and implementation of recommended controls are required to prevent compromise.
