Bu ornek, Emotet'in modüler DLL mimarisinin bir parcasidir. Yuksek entropy ve dusuk string sayisi (506), guclu bir packer veya sifreleme katmaninin varligina isaret etmektedir. Statik string analizinde cleartext C2, URL veya email IOC bulunamadi.

Emotet Mimarisi

  • Loader DLL: Ana modul, bellekte calisir, diskte nadir iz brakir
  • C2 Haberlesme: Sifreli HTTP POST, C2 listesi sablonlarda sakli
