TRITON

ICS malware discovered in 2017 that targeted Schneider Electric Triconex safety instrumented systems at a petrochemical plant.

Definition

Also called TRISIS or HatMan, it reprogrammed SIS controllers via a compromised engineering workstation and was discovered when it accidentally triggered a safe shutdown. It was the first known malware designed to disable safety systems that protect human life.

Example

TRITON is cited to justify isolating SIS networks and enforcing key-switch run modes on safety controllers.

Exam tip

First malware to target safety instrumented systems.
