Triton, also known as Trisis, the ICS malware has been designed to target Triconex Safety Instrumented System (SIS) controllers made by Schneider Electric. The attack was launched against an industrial organization in the Middle East, according to researchers. The malware is emerging as a severe threat to critical infrastructures, just like Stuxnet IronGate, and Industroyer, because of its capabilities to cause physical damage or shut down operations. An attacker can typically reprogram the SIS logic to falsely shut down a process that is actually in a safe state.
