Why this verdict

The suspicious score of 44/100 is the fusion of 3 weighted signals:

• Embedded network infrastructure: https://netcdn.tw/app/431946152/earn-free-robux-2021-game-hack - static signal, weight 0.35, confidence 0.60
• Document active content: uri-action - static signal, weight 0.30, confidence 0.60
• Packing/obfuscation: high-entropy-blob - 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.
