MITRE ATT&CK
Why this verdict
The malicious score of 79/100 is the fusion of 6 weighted signals:
- Kaspersky (KVRT) flagged HEUR:Trojan-PSW.Java.Stealer.gen (rule
HEUR:Trojan-PSW.Java.Stealer.gen) - engine signal, weight 0.55, confidence 0.85 - Contacted 27 external host(s) and 12 HTTP request(s) at runtime - network signal, weight 0.40, confidence 0.80
- 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
- Observed at runtime: Modify Registry (T1112) (rule
Modify Registry) - dynamic signal, weight 0.12, confidence 0.90 - Memory forensics: 3 finding(s) elsewhere in the guest, not attributed to this sample, e.g. RWX/private injected region in javaw.exe (pid 8992) (rule
windows.malfind.Malfind) - memory signal, weight 0.05, confidence 0.30
