upload files that contribute to the growing amount of warez. Distribution via compromised FTP servers Prior to the development of modern peer-to-peer sharing systems and home broadband service, sharing warez sometimes involved warez groups scanning the Internet for weakly secured computer systems with high-speed connections. These weakly secured systems would be compromised by exploiting the poor FTP security, creating a special directory on the server with an unassuming name to contain the illegal content. A common mistake of early FTP administrators was to permit a directory named /incoming that allows full read and write access by external users, but the files themselves in /incoming were hidden; by creating a directory inside /incoming, this hidden directory would then allow normal file viewing. Users of the compromised site would be directed to log in and go to a location such as /incoming/data/warez to find the warez content. Messages could be left for other warez users by uploading a plain text file with the message inside. Hackers would also use known software bugs to illicitly gain full administrative remote control over a computer, and install a hidden FTP service to host their wares. This FTP service was usually running on an unusual port number, or with a non-anonymous login name like "login: warez / Password: warez" to help prevent discovery by legitimate users; information about this compromised system would then be distributed to a select group of people who were part of the warez scene. It was important for warez group members to regulate who had access to these compromised FTP servers, to keep the network bandwidth usage low. A site that suddenly became very popular would be noticed by the real owners of the equipment, as their business systems became slow or low on disk space; investigation of system usage would then inevitably result in discovery and removal of the warez, and tightening of the site security. Automated warez distribution via IRC bots As the ability to compromise and attain full remote control of business servers became more developed, the warez groups would hack a server and install an IRC bot on the compromised systems alongside the FTP service, or the IRC bot would provide file sharing directly by itself. This software would intelligently regulate access to the illicit data by using file queues to limit bandwidth usage, or by only running during off-hours overnight when the business owning the compromised hardware
