Why this verdict

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

• Embedded link rated malicious by URL analysis: http://perpustakaan.pn-tapaktuan.go.id/repository/coin-master--hack_GM406889139.pdf - network signal, weight 0.70, confidence 0.80
• Embedded network infrastructure: https://netcdn.online/app/431946152/rbx-sites-game-hack, http://perpustakaan.pn-tapaktuan.go.id/repository/get-free-robux_GM431946152.pdf, http://perpustakaan.pn-tapaktuan.go.id/repository/coin-master-free-spins-link-facebook-page_GM406889139.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.
