Why this verdict

The malicious score of 99/100 is the fusion of 12 weighted signals:

• Process injection API combination (rule Windows_Injection_Api_Combo) - yara signal, weight 0.65, confidence 0.90
• Microsoft Defender flagged Trojan:Win64/Zusy.LVN!MTB (rule Trojan:Win64/Zusy.LVN!MTB) - engine signal, weight 0.55, confidence 0.85
• Emsisoft (Emergency Kit) flagged Gen:Variant.Lazy.731016 (rule Gen:Variant.Lazy.731016) - 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
• capture keystrokes (rule capture keystrokes) - capa signal, weight 0.40, confidence 0.80
• YARA: Yara-Rules community flagged YR_AntiDebug_Checks (rule YR_AntiDebug_Checks) - engine signal, weight 0.35, confidence 0.70
• YARA: MalwareAnalyser built-in flagged Windows_Injection_Api_Combo (rule Windows_Injection_Api_Combo) - engine signal, weight 0.35, confidence 0.70
