• 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
• Packing/obfuscation: high-entropy-sections:325ksgaj, MinGW - static signal, weight 0.25, confidence 0.55

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.
