What it detects

This rule detects schtasks creating the TaskHandler task set to run at startup as SYSTEM with highest privileges from the C Drivers directory in the Cambodia-focused SparkRAT chain. Adversaries register a SYSTEM-level onstart task to relaunch their sideloading host under maximum privilege. The task name combined with the SYSTEM run context and C Drivers path is distinctive.
