Fareit (closely associated with Pony) is credential-stealing spyware. Per Malwarebytes' description of Spyware.Pony, it may run in the background and silently collect information about the system, connected users, and network activity. It harvests stored credentials from browsers, email, and FTP clients and can act as a downloader for additional malware; the leak of the Pony Loader source code led to its use by many threat actors.
