Why this verdict

The malicious score of 85/100 is the fusion of 9 weighted signals:

• YARA: JPCERT/CC flagged JPCERT_HUILoader_PlugX_SideLoad (rule JPCERT_HUILoader_PlugX_SideLoad) - engine signal, weight 0.60, confidence 0.70
• Contacted 29 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:/19,/32,/46,/63,/99,/112,/124 (rule high-entropy-sections:/19,/32,/46,/63,/99,/112,/124) - engine signal, weight 0.35, confidence 0.70
• Embedded network infrastructure: 5.4.32.5, 4.52.5.4, 62.5.4.72 - static signal, weight 0.35, confidence 0.60
• Packing/obfuscation: high-entropy-sections:/19,/32,/46,/63,/99,/112,/124 - static signal, weight 0.25, confidence 0.55
• enumerate processes (rule enumerate processes) - capa signal, weight 0.20, confidence 0.60
• Observed at runtime: Modify Registry (T1112) (rule Modify Registry) - dynamic signal, weight 0.12, confidence 0.90
• Extracted generic config (15 C2) (generic/advisory) - engine signal, weight 0.15, confidence 0.30
• 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
