Why this verdict
The suspicious score of 54/100 is the fusion of 2 weighted signals:
- Obfuscated javascript script: dynamic-exec, defense-evasion (layers: concat) (rule
script-deobfuscation) - static signal, weight 0.55, confidence 0.75 - Embedded network infrastructure: http://developers.facebook.com/policy/, https://connect.facebook.net/, https://gw.conversionsapigateway.com - static signal, weight 0.35, confidence 0.60
