Why this verdict

The suspicious score of 62/100 is the fusion of 4 weighted signals:

• capture keystrokes (rule capture keystrokes) - capa signal, weight 0.40, confidence 0.80
• YARA: JPCERT/CC flagged JPCERT_HUILoader_PlugX_SideLoad (rule JPCERT_HUILoader_PlugX_SideLoad) - engine signal, weight 0.35, confidence 0.70
• Embedded network infrastructure: http://www.7-zip.org/ - static signal, weight 0.35, confidence 0.60
• 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.
