MITRE ATT&CK
Why this verdict
The malicious score of 94/100 is the fusion of 10 weighted signals:
- Emsisoft (Emergency Kit) flagged Gen:Variant.Lazy.123351 (rule
Gen:Variant.Lazy.123351) - engine signal, weight 0.55, confidence 0.85 - 1 behavioral detection(s) across 1 rule(s): LOLBin: rundll32 suspicious invocation [medium] (rule
tl-lolbin-rundll32) - dynamic signal, weight 0.40, confidence 0.90 - Contacted 29 external host(s) and 15 HTTP request(s) at runtime - network signal, weight 0.40, confidence 0.80
- Detect It Easy (packer/type) flagged DIE:Microsoft Linker (rule
DIE:Microsoft Linker) - engine signal, weight 0.35, confidence 0.70 - LIEF (executable format parser) flagged lief:invalid-authenticode (rule
lief:invalid-authenticode) - engine signal, weight 0.35, confidence 0.70 - MalwareAnalyser heuristics (entropy/packer) flagged high-entropy-sections:.URUS1 (rule
high-entropy-sections:.URUS1) - engine signal, weight 0.35, confidence 0.70 - Embedded network infrastructure: https://secure.comodo.net/CPS0C - static signal, weight 0.35, confidence 0.60
- Packing/obfuscation: high-entropy-sections:.URUS1, Microsoft Linker - 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: 2 finding(s) elsewhere in the guest, not attributed to this sample, e.g. SSDT hook (rule
windows.ssdt.SSDT) - memory signal, weight 0.05, confidence 0.30
