Why this verdict

The malicious score of 96/100 is the fusion of 6 weighted signals:

• ClamAV (daily) flagged Win.Trojan.Generic-9862772-0 (rule Win.Trojan.Generic-9862772-0) - engine signal, weight 0.90, confidence 0.95
• capture keystrokes (rule capture keystrokes) - capa signal, weight 0.40, confidence 0.80
• YARA: JPCERT/CC flagged JPCERT_HUILoader_PlugX_SideLoad (rule JPCERT_HUILoader_PlugX_SideLoad) - engine signal, weight 0.35, confidence 0.70
• YARA: Yara-Rules community flagged YR_AntiDebug_Checks (rule YR_AntiDebug_Checks) - engine signal, weight 0.35, confidence 0.70
• LIEF (executable format parser) flagged lief:invalid-authenticode (rule lief:invalid-authenticode) - engine signal, weight 0.35, confidence 0.70
• enumerate processes (rule enumerate processes) - capa signal, weight 0.20, confidence 0.60
