Why this verdict
The malicious score of 89/100 is the fusion of 9 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:Hoax.PDF.Phish.gen (rule
HEUR:Hoax.PDF.Phish.gen) - 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: http://klinok-saintp.ru/files/dipekegajajulabipi.pdf, http://ger.versa.ru/documents/files/10532875817.pdf, https://villatoscana-pi.it/userfiles/file/vixizazonozubimi.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
- Contacted 9 external host(s) at runtime - network signal, weight 0.12, confidence 0.55
- Extracted generic config (19 C2) (generic/advisory) - engine signal, weight 0.15, confidence 0.30
- Memory forensics: 4 finding(s) elsewhere in the guest, not attributed to this sample, e.g. RWX/private injected region in Acrobat.exe (pid 9032) (rule
