Why this verdict

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

• Embedded link rated suspicious by URL analysis: http://perpustakaan.pn-tapaktuan.go.id/repository/roblox-zall-site-free-robux_GM431946152.pdf - network signal, weight 0.40, 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.
