Why this verdict
The malicious score of 76/100 is the fusion of 5 weighted signals:
- Kaspersky (KVRT) flagged HEUR:Trojan.MSOffice.Generic (rule
HEUR:Trojan.MSOffice.Generic) - engine signal, weight 0.55, confidence 0.85 - Document contains macros/active content: xlm-macro - static signal, weight 0.35, confidence 0.75
- MalwareAnalyser heuristics (entropy/packer) flagged high-entropy-blob (rule
high-entropy-blob) - engine signal, weight 0.35, confidence 0.70 - Packing/obfuscation: high-entropy-blob - static signal, weight 0.25, confidence 0.55
- Contacted 12 external host(s) at runtime - network signal, weight 0.12, confidence 0.55
