Why this verdict
The suspicious score of 54/100 is the fusion of 2 weighted signals:
- Obfuscated powershell script: dynamic-exec, defense-evasion (rule
script-deobfuscation) - static signal, weight 0.55, confidence 0.75 - Embedded network infrastructure: http://www.broofa.com - static signal, weight 0.35, confidence 0.60
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.
