New malware attacks safety systems

Emergency shutdown systems have been targeted by a new malware attack.

Threat: A malware attack called TRITON targeted control systems that provide emergency shutdowns for industrial processes. TRITON was built for Triconex Safety Instrumented System (SIS) controllers.

Damage risk: The malware can reprogram the SIS to allow unsafe conditions, leading to physical hazards and threats to human safety.

Exploited flaw: TRITON added a malicious program to the execution table of the controller, allowing it to continue operating with TRITON inside.

Fixes/Workarounds: Implement hardware features, like switches controlled by physical keys, that allow systems to be manually controlled.
