Why this verdict

The malicious score of 75/100 is the fusion of 4 weighted signals:

• Embedded link rated malicious by URL analysis: http://library.futureuniversity.com/repository/free-robux_GM431946152.pdf - network signal, weight 0.70, confidence 0.80
• Embedded network infrastructure: http://netcdn.co/app/431946152/free-roblox-robux-accounts-2021-game-hack, http://library.futureuniversity.com/repository/coin-master-free-spins-link-fb_GM406889139.pdf, http://library.futureuniversity.com/repository/ultimate-hack-for-roblox-unpatchable-level-7_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.
