Detections (4 of 52 engines)

• MalwareAnalyser heuristics (entropy/packer): Turbo Linker
• YARA: JPCERT/CC: JPCERT_HUILoader_PlugX_SideLoad
• Detect It Easy (packer/type): DIE:Turbo Linker
• Kaspersky (KVRT): not-a-virus:HEUR:Downloader.Win32.Softonic.gen

Why this verdict

The suspicious score of 61/100 is the fusion of 4 weighted signals:

• 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:Turbo Linker (rule DIE:Turbo Linker) - engine signal, weight 0.35, confidence 0.70
• Embedded network infrastructure: https://jrsoftware.org/ishelp/index.php?topic=setupcmdline - static signal, weight 0.35, confidence 0.60
• Packing/obfuscation: Turbo 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.
