Why this verdict
The malicious score of 78/100 is the fusion of 5 weighted signals:
- Emsisoft (Emergency Kit) flagged PDF.Spam.Heur.1 (rule
PDF.Spam.Heur.1) - 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 network infrastructure: https://cctraff.ru/strik?keyword=circle+of+4ths+and+5ths+pdf, https://site-1036869.mozfiles.com/files/1036869/bofujojokolu.pdf, https://site-1037018.mozfiles.com/files/1037018/finaput.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
