For completeness, the following types of tools have been used in campaigns leveraging vulnerable FTP servers:

When an administrator runs the installer or starts the server service, the application loads the malicious code via DLL hijacking or direct process injection.

When the user extracts the archive and launches the primary executable, the Windows operating system searches the local application directory before looking in system folders (like System32 ). The application inadvertently loads the attacker’s local DLL file instead of the official system file, initiating the payload. 3. Evasion and Persistence Mechanisms
