MITRE ATT&CK
Why this verdict
The suspicious score of 58/100 is the fusion of 4 weighted signals:
- Embedded link rated suspicious by URL analysis: http://files.jlnjspac.org/uploads/1/3/1/8/131856516/173097.pdf - network signal, weight 0.40, confidence 0.60
- Embedded network infrastructure: https://cctraff.ru/strik?keyword=vesirig+mode+d+emploi, http://files.jlnjspac.org/uploads/1/3/1/8/131856516/173097.pdf, http://ronul.canaanchristianministries.co.uk/uploads/1/3/1/8/131857758/wojatogutidexes.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
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.
