• Process injection API combination (rule Windows_Injection_Api_Combo) - yara signal, weight 0.65, confidence 0.90
• 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
