Detections (3 of 55 engines)

• MalwareAnalyser heuristics (entropy/packer): UPX
• YARA: JPCERT/CC: JPCERT_HUILoader_PlugX_SideLoad
• Detect It Easy (packer/type): DIE:Microsoft Linker

Why this verdict

The malicious score of 77/100 is the fusion of 5 weighted signals:

• YARA: JPCERT/CC flagged JPCERT_HUILoader_PlugX_SideLoad (rule JPCERT_HUILoader_PlugX_SideLoad) - engine signal, weight 0.60, confidence 0.70
• Detect It Easy (packer/type) flagged DIE:Microsoft Linker (rule DIE:Microsoft Linker) - engine signal, weight 0.35, confidence 0.70
• MalwareAnalyser heuristics (entropy/packer) flagged UPX (rule UPX) - engine signal, weight 0.35, confidence 0.70
• Embedded network infrastructure: https://secure.comodo.net/CPS0A, https://secure.comodo.net/CPS0C - static signal, weight 0.35, confidence 0.60
• Packing/obfuscation: UPX, high-entropy-sections:UPX1, Microsoft Linker - 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.
