• Microsoft Defender: Trojan:Win32/Copak.GPAB!MTB
• Emsisoft (Emergency Kit): Gen:Variant.Cerbu.246963
• Kaspersky (KVRT): HEUR:Trojan.Win32.Copak.vho

Why this verdict

The malicious score of 76/100 is the fusion of 3 weighted signals:

• Microsoft Defender flagged Trojan:Win32/Copak.GPAB!MTB (rule Trojan:Win32/Copak.GPAB!MTB) - engine signal, weight 0.55, confidence 0.85
• Emsisoft (Emergency Kit) flagged Gen:Variant.Cerbu.246963 (rule Gen:Variant.Cerbu.246963) - engine signal, weight 0.55, confidence 0.85
• Packing/obfuscation: high-entropy-sections:.bss - static signal, weight 0.25, confidence 0.55

Dynamic analysis

No runtime behaviour was captured for this sample, so the analysis above is static only. That is a limit of this run rather than evidence the sample does nothing.
