Why this verdict

The malicious score of 88/100 is the fusion of 6 weighted signals:

• Emsisoft (Emergency Kit) flagged PDF.Spam.Heur.1 (rule PDF.Spam.Heur.1) - engine signal, weight 0.55, confidence 0.85
• Kaspersky (KVRT) flagged HEUR:Trojan.Script.Generic (rule HEUR:Trojan.Script.Generic) - engine signal, weight 0.55, confidence 0.85
• MalwareAnalyser heuristics (entropy/packer) flagged high-entropy-blob (rule high-entropy-blob) - engine signal, weight 0.35, confidence 0.70

• 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.
