Why this verdict

The malicious score of 97/100 is the fusion of 10 weighted signals:

• Microsoft Defender flagged Trojan:Win32/Glupteba!pz (rule Trojan:Win32/Glupteba!pz) - engine signal, weight 0.55, confidence 0.85
• Emsisoft (Emergency Kit) flagged Gen:Variant.Razy.870640 (rule Gen:Variant.Razy.870640) - engine signal, weight 0.55, confidence 0.85
• Trellix Stinger (McAfee) flagged Glupteba-FUBP!523ABA248BD2 (rule Glupteba-FUBP!523ABA248BD2) - engine signal, weight 0.55, confidence 0.85
• Kaspersky (KVRT) flagged HEUR:Trojan.Win32.Copak.pef (rule HEUR:Trojan.Win32.Copak.pef) - engine signal, weight 0.55, confidence 0.85
• Contacted 15 external host(s) and 11 HTTP request(s) at runtime - network signal, weight 0.40, confidence 0.80
• MalwareAnalyser heuristics (entropy/packer) flagged high-entropy-sections:.text (rule high-entropy-sections:.text) - engine signal, weight 0.35, confidence 0.70
• Packing/obfuscation: high-entropy-sections:.text - static signal, weight 0.25, confidence 0.55
• Dropped 1 executable file(s) at runtime - dynamic signal, weight 0.20, confidence 0.60
• Observed at runtime: Modify Registry (T1112) (rule Modify Registry) - dynamic signal, weight 0.12, confidence 0.90
