Why this verdict

The malicious score of 83/100 is the fusion of 6 weighted signals:

• access stored credentials (rule access stored credentials) - capa signal, weight 0.50, confidence 0.80
• 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
• YARA: Trellix/McAfee ATR flagged ATR_REvil_Sodinokibi (rule ATR_REvil_Sodinokibi) - 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://docs.rs/getrandom#nodejs-es-module-support!dangling, 20.19.18.17, 16.15.14.13 - static signal, weight 0.35, 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.
