Why this verdict

The malicious score of 83/100 is the fusion of 7 weighted signals:

• UPX packer section names (rule Packer_UPX_Sections) - yara signal, weight 0.40, confidence 0.90
• YARA: JPCERT/CC flagged JPCERT_HUILoader_PlugX_SideLoad (rule JPCERT_HUILoader_PlugX_SideLoad) - engine signal, weight 0.35, confidence 0.70
• YARA: MalwareAnalyser community pack flagged TL_UPX_Packed (rule TL_UPX_Packed) - engine signal, weight 0.35, confidence 0.70
• YARA: Yara-Rules community flagged YR_AntiDebug_Checks (rule YR_AntiDebug_Checks) - engine signal, weight 0.35, confidence 0.70
• Embedded network infrastructure: https://secure.comodo.net/CPS0A - static signal, weight 0.35, confidence 0.60
• Packing/obfuscation: high-entropy-sections:.data0 - 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.
