Crimes of Opportunity: Increasing Frequency of Low Sophistication Operational Technology Compromises

Attacks on control processes supported by operational technology (OT) are often perceived as necessarily complex. This is because disrupting or modifying a control process to cause a predictable effect is often quite difficult and can require a lot of time and resources. However, Mandiant Threat Intelligence has observed simpler attacks, where actors with varying levels of skill and resources use common IT tools and techniques to gain access to and interact with exposed OT systems.

Rather, the compromises appear to be driven by threat actors who are motivated to achieve ideological, egotistical, or financial objectives by taking advantage of an ample supply of internet-connected OT systems. As the actors are not interested in causing specific physical outcomes, they target whatever is available on the internet.
