• 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
• Embedded link rated suspicious by URL analysis: http://files.sfghosthunt.com/uploads/1/3/2/6/132695365/vutopesezasiro.pdf - network signal, weight 0.40, confidence 0.60
• Embedded network infrastructure: https://ttraff.me/wix?keyword=trek+antelope+820+parts, http://files.sfghosthunt.com/uploads/1/3/2/6/132695365/vutopesezasiro.pdf, http://files.nnnnn.name/uploads/1/3/2/6/132681560/80f61.pdf - static signal, weight 0.35, 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.
