Proprietary Back Doors

Other examples of proprietary malware

Nonfree (proprietary) software is very often malware (designed to mistreat the user). Nonfree software is controlled by its developers, which puts them in a position of power over the users; that is the basic injustice. The developers often exercise that power to the detriment of the users they ought to serve.

A “back door” in a program is a channel designed to send the program commands from someone who is not supposed to be in control of the computer where the program is installed.

Here are examples of demonstrated back doors in proprietary software. They are sorted out according to what they are known to allow. Back doors that allow full control over the operating system are said to be “universal”.

If you know of an example that ought to be in this page but isn't here, please write to <webmasters@gnu.org> to inform us. Please include the URL of a trustworthy reference or two to serve as specific substantiation.
