What it detects

This rule detects execution of IntelAudioService.exe with the specific appmodel, StateRepository and Service command-line arguments used to launch the SPECTRALVIPER backdoor. The behavior is linked to the OceanLotus (APT32) espionage operation that shifted from external to domestic targeting. Detecting this masqueraded launcher pattern is important because attackers use it to covertly start their implant and blend with legitimate audio service activity.
