MITRE ATT&CK
Why this verdict
The malicious score of 91/100 is the fusion of 7 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:Trojan.PDF.Agent.gen (rule
HEUR:Trojan.PDF.Agent.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 link rated suspicious by URL analysis: http://misefiz.cambridgeintlschool.com/uploads/1/3/1/3/131383541/bced432f6.pdf - network signal, weight 0.40, confidence 0.60
