Why this verdict

The malicious score of 99/100 is the fusion of 11 weighted signals:

2 behavioral detection(s) across 2 rule(s): Credential Access: browser credential store read [high] (rule tl-browser-credential-access) - dynamic signal, weight 0.63, confidence 0.90
Microsoft Defender flagged Trojan:Win32/Wacatac.B!ml (rule Trojan:Win32/Wacatac.B!ml) - engine signal, weight 0.55, confidence 0.85
Kaspersky (KVRT) flagged HEUR:Trojan.Win32.Generic (rule HEUR:Trojan.Win32.Generic) - 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 6 HTTP request(s) at runtime - network signal, weight 0.40, confidence 0.80
Anti-analysis: T1082, T1497, T1497.001 - dynamic signal, weight 0.40, confidence 0.75
Detect It Easy (packer/type) flagged DIE:Microsoft Linker (rule DIE:Microsoft Linker) - engine signal, weight 0.35, confidence 0.70
MalwareAnalyser heuristics (entropy/packer) flagged Themida/VMProtect (rule Themida/VMProtect) - engine signal, weight 0.35, confidence 0.70
Embedded network infrastructure: https://d.symcb.com/rpa0, http://s.symcb.com/universal-root.crl0, https://d.symcb.com/rpa0@ - static signal, weight 0.35, confidence 0.60
Packing/obfuscation: Themida/VMProtect, high-entropy-sections: , , , ,.boot, Microsoft Linker - static signal, weight 0.25, confidence 0.55
