Microsoft Defender flagged Trojan:Win32/Salgorea.VRR!MTB (rule Trojan:Win32/Salgorea.VRR!MTB) - engine signal, weight 0.55, confidence 0.85
Kaspersky (KVRT) flagged Backdoor.Win32.Salgorea.ck (rule Backdoor.Win32.Salgorea.ck) - engine signal, weight 0.55, confidence 0.85
YARA: JPCERT/CC flagged JPCERT_HUILoader_PlugX_SideLoad (rule JPCERT_HUILoader_PlugX_SideLoad) - engine signal, weight 0.60, confidence 0.70
Observed at runtime: Windows Service (T1543.003) (rule Windows Service) - dynamic signal, weight 0.40, confidence 0.90
1 behavioral detection(s) across 1 rule(s): Windows Service Installation [medium] (rule tl-service-install) - dynamic signal, weight 0.40, confidence 0.90
