Why this verdict

The malicious score of 99/100 is the fusion of 10 weighted signals:

• ClamAV (daily) flagged Win.Trojan.Finfish-9787043-0 (rule Win.Trojan.Finfish-9787043-0) - engine signal, weight 0.90, confidence 0.95
• Microsoft Defender flagged Trojan:Win32/Salgorea!pz (rule Trojan:Win32/Salgorea!pz) - engine signal, weight 0.55, confidence 0.85
• Emsisoft (Emergency Kit) flagged Trojan.Agent.GIKJ (rule Trojan.Agent.GIKJ) - engine signal, weight 0.55, confidence 0.85
• Kaspersky (KVRT) flagged Trojan.Win32.Agent.xaktra (rule Trojan.Win32.Agent.xaktra) - engine signal, weight 0.55, confidence 0.85
• Observed at runtime: Windows Service (T1543.003) (rule Windows Service) - dynamic signal, weight 0.40, confidence 0.90
• Contacted 20 external host(s) and 9 HTTP request(s) at runtime - network signal, weight 0.40, confidence 0.80
• MalwareAnalyser heuristics (entropy/packer) flagged high-entropy-sections:.l2 (rule high-entropy-sections:.l2) - engine signal, weight 0.35, confidence 0.70
