• 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
• persist via registry run key (rule persist via registry run key) - capa signal, weight 0.35, confidence 0.60
• Embedded network infrastructure: http://0.0.0.0/download.exe - static signal, weight 0.35, confidence 0.60
• communicate over HTTP (rule communicate over HTTP) - capa signal, weight 0.30, confidence 0.60
• enumerate processes (rule enumerate processes) - capa signal, weight 0.20, confidence 0.60
