Why this verdict

The suspicious score of 58/100 is the fusion of 4 weighted signals:

• Embedded link rated suspicious by URL analysis: http://sistem.amikomsolo.ac.id/perpus/repository/free-roblox-clothes-codes-2021_GM431946152.pdf - network signal, weight 0.40, confidence 0.60
• Embedded network infrastructure: http://netcdn.co/app/431946152/free-robux-code-giveaway-live-game-hack, http://sistem.amikomsolo.ac.id/perpus/repository/free-roblox-clothes-codes-2021_GM431946152.pdf, http://sistem.amikomsolo.ac.id/perpus/repository/strucid-roblox-hacks_GM431946152.pdf - 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.
