Why this verdict

The suspicious score of 54/100 is the fusion of 2 weighted signals:

• Obfuscated javascript script: dynamic-exec, defense-evasion (layers: base64) (rule script-deobfuscation) - static signal, weight 0.55, confidence 0.75
• Embedded network infrastructure: https://blockly-demo.appspot.com/static/media/ - static signal, weight 0.35, confidence 0.60

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.
