Why this verdict

The malicious score of 95/100 is the fusion of 6 weighted signals:

• ClamAV (daily) flagged Win.Malware.Cymt-10023133-0 (rule Win.Malware.Cymt-10023133-0) - engine signal, weight 0.90, confidence 0.95
• YARA: JPCERT/CC flagged JPCERT_HUILoader_PlugX_SideLoad (rule JPCERT_HUILoader_PlugX_SideLoad) - engine signal, weight 0.35, confidence 0.70
• Detect It Easy (packer/type) flagged DIE:MinGW (rule DIE:MinGW) - engine signal, weight 0.35, confidence 0.70
• Embedded network infrastructure: http://wecan.hasthe.techno - static signal, weight 0.35, confidence 0.60
• Packing/obfuscation: UPX, high-entropy-sections:UPX1, MinGW - static signal, weight 0.25, confidence 0.55
• enumerate processes (rule enumerate processes) - capa signal, weight 0.20, confidence 0.60

Dynamic analysis

No runtime behaviour was captured for this sample, so the analysis above is static only. That is a limit of this run rather than evidence the sample does nothing.
