• Process injection API combination (rule Windows_Injection_Api_Combo) - yara signal, weight 0.65, confidence 0.90
• execute via PowerShell (rule execute via PowerShell) - capa signal, weight 0.40, confidence 0.80
• YARA: JPCERT/CC flagged JPCERT_Emotet (rule JPCERT_Emotet) - engine signal, weight 0.35, confidence 0.70
