- Embedded link rated malicious by URL analysis: https://cdn-cms.f-static.net/uploads/4369329/normal_5f88ad4a4c0ab.pdf - network signal, weight 0.70, confidence 0.80
- Embedded network infrastructure: https://traffnew.ru/123?keyword=2d+lc+monoclonal+antibody, https://cdn-cms.f-static.net/uploads/4365555/normal_5f8dfa8adde7e.pdf, https://cdn-cms.f-static.net/uploads/4370541/normal_5f88d08ded6f2.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.
