Why this verdict

The malicious score of 86/100 is the fusion of 5 weighted signals:

• Process injection API combination (rule Windows_Injection_Api_Combo) - yara signal, weight 0.65, confidence 0.90
• execute via PowerShell (rule execute via PowerShell) - capa signal, weight 0.40, confidence 0.80
• YARA: MalwareAnalyser community pack flagged TL_Shellcode_VirtualAlloc_Exec (rule TL_Shellcode_VirtualAlloc_Exec) - engine signal, weight 0.35, confidence 0.70
• Detect It Easy (packer/type) flagged DIE:Confuser 1.X (rule DIE:Confuser 1.X) - engine signal, weight 0.35, confidence 0.70
• Packing/obfuscation: high-entropy-sections:.text, Confuser 1.X - 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.
