Why this verdict

The malicious score of 92/100 is the fusion of 8 weighted signals:

• Microsoft Defender flagged Trojan:Win32/Tiggre!rfn (rule Trojan:Win32/Tiggre!rfn) - engine signal, weight 0.55, confidence 0.85
• Kaspersky (KVRT) flagged HEUR:Trojan-Spy.Win32.Clipper.gen (rule HEUR:Trojan-Spy.Win32.Clipper.gen) - engine signal, weight 0.55, confidence 0.85
• Contacted 24 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 UPX (rule UPX) - engine signal, weight 0.35, confidence 0.70
• Packing/obfuscation: UPX, high-entropy-sections:UPX1, Microsoft Linker - static signal, weight 0.25, confidence 0.55
• Observed at runtime: Modify Registry (T1112) (rule Modify Registry) - dynamic signal, weight 0.12, confidence 0.90
• Memory forensics: 2 finding(s) elsewhere in the guest, not attributed to this sample, e.g. SSDT hook (rule windows.ssdt.SSDT) - memory signal, weight 0.05, confidence 0.30
