2023 saw an uptick of cyberattacks across many industries. Our infographic focuses on cyberattacks in 2023 that impacted industrial operations, specifically Operational Technology (OT) security and Industrial Controls Systems (ICS) that are commonly used within critical and important infrastructure.

The consequences from the cyberattacks in our infographic range from a short 1-day shutdown to an entire operation being stopped and staff being furloughed. It is also probable that many other industrial cyberattacks occurred in this 2023 time-period but were not serious enough to require being reported, or that were exempt from being reported for other reasons.
