Why this verdict

The malicious score of 91/100 is the fusion of 3 weighted signals:

• ClamAV (daily) flagged Win.Trojan.Zbot-64619 (rule Win.Trojan.Zbot-64619) - engine signal, weight 0.90, confidence 0.95
• YARA: JPCERT/CC flagged JPCERT_HUILoader_PlugX_SideLoad (rule JPCERT_HUILoader_PlugX_SideLoad) - engine signal, weight 0.35, confidence 0.70
• Packing/obfuscation: UPX - static signal, weight 0.25, confidence 0.55
