• execute via PowerShell (rule execute via PowerShell) - capa signal, weight 0.40, confidence 0.80
• Detect It Easy (packer/type) flagged DIE:.NET Reactor 4.8-4.9 (rule DIE:.NET Reactor 4.8-4.9) - engine signal, weight 0.35, confidence 0.70
• Packing/obfuscation: high-entropy-sections:.text, .NET Reactor 4.8-4.9 - 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.
