Ransomware Threat to OT

Revision Date

On June 9, 2021, CISA published Rising Ransomware Threat to Operational Technology Assets, a fact sheet for critical infrastructure owners and operators detailing the rising threat of ransomware to operational technology (OT) assets and control systems. The document includes several recommended actions and resources that critical infrastructure entities should implement to reduce the risk of this threat.

The guidance:

  • Provides steps to prepare for, mitigate against, and respond to attacks;
  • Details how the dependencies between an entity’s IT and OT systems can provide a path for attackers; and
  • explains how to reduce the risk of severe business degradation if affected by ransomware

Given the importance of critical infrastructure to national security and America’s way of life, CISA published this fact sheet to help organizations build effective resilience.
