Why this verdict

The malicious score of 96/100 is the fusion of 6 weighted signals:

• ClamAV (daily) flagged Win.Malware.Hoax-10029094-0 (rule Win.Malware.Hoax-10029094-0) - 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
• YARA: Yara-Rules community flagged YR_Packer_ASPack_MPRESS (rule YR_Packer_ASPack_MPRESS) - engine signal, weight 0.35, confidence 0.70
• Detect It Easy (packer/type) flagged DIE:Microsoft Linker (rule DIE:Microsoft Linker) - engine signal, weight 0.35, confidence 0.70
• Embedded network infrastructure: http://www.gnu.org/software/coreutils/, http://translationproject.org/team/, http://gnu.org/licenses/gpl.html - static signal, weight 0.35, confidence 0.60
• Packing/obfuscation: ASPack, high-entropy-sections:.text, 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.
