Notesvb.msi -- "Notes" = not uygulaması (OneNote, Notepad taklidi?) -- "vb" = Visual Basic (resmi VB uygulama gibi görünür) -- ".msi" = Windows yükleyici paketi -- QakBot: MSI teslimatı (2022+ itibaren tercih edilen yöntem)
ConnectNamedPipe + DisconnectNamedPipe
ConnectNamedPipe -- named pipe bağlantısı DisconnectNamedPipe -- named pipe kesimi -- IcedID2 ile aynı pattern: her iki trojan da named pipe kullanıyor -- QakBot: modüler mimari → bileşenler named pipe ile haberleşir -- Named pipe: ağ trafiği olmadan süreçlerarası C2 segmentasyonu
