Background
Zeppelin is Delphi-based ransomware distributed under an as-a-service model. Cylance researchers describe it as a clear descendant of the known VegaLocker, yet classify it as a distinct family owing to extra modules that make Zeppelin far more configurable than VegaLocker. It exists in both DLL and EXE executable forms.
