execute via PowerShell (rule execute via PowerShell) - capa signal, weight 0.40, confidence 0.80
Contacted 4 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
capa (capabilities) flagged capability:execution/powershell (rule capability:execution/powershell) - engine signal, weight 0.35, confidence 0.70
MalwareAnalyser heuristics (entropy/packer) flagged Microsoft Linker (rule Microsoft Linker) - engine signal, weight 0.35, confidence 0.70
