Why this verdict

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

• Embedded network infrastructure: http://netcdn.tw/app/479516143/how-to-get-minecraft-java-edition-for-free-game-hack, http://winnerwater.com.tw/image/data/files/play-minecraft-pocket-edition-for-free_GM479516143.pdf, http://winnerwater.com.tw/image/data/files/free-100-robux_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.
