• ClamAV (daily) flagged Win.Packed.Zusy-9645559-0 (rule Win.Packed.Zusy-9645559-0) - engine signal, weight 0.90, confidence 0.95
• 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
• Contacted 15 external host(s) and 11 HTTP request(s) at runtime - network signal, weight 0.40, confidence 0.80
• Detect It Easy (packer/type) flagged DIE:Microsoft Linker (rule DIE:Microsoft Linker) - engine signal, weight 0.35, confidence 0.70
• MalwareAnalyser heuristics (entropy/packer) flagged high-entropy-sections: (rule high-entropy-sections:) - engine signal, weight 0.35, confidence 0.70
