Warden Client
Blizzard has made use of a special form of software known as the 'Warden Client'. The Warden client is known to be used with Blizzard's Online Games such as Diablo and World of Warcraft, and the Terms of Service contain a clause consenting to the Warden software's RAM scans while a Blizzard game is running.
The Warden client scans a small portion of the code segment of running processes in order to determine whether any third-party programs are running. The goal of this is to detect and address players who may be attempting to run unsigned code or third party programs in the game. This determination of third party programs is made by hashing the scanned strings and comparing the hashed value to a list of hashes assumed to correspond to banned third party programs. The Warden's reliability in correctly discerning legitimate versus illegitimate actions was called into question when a large scale incident happened when many Linux users were banned after an update to Warden caused it to incorrectly detect Cedega as a cheat program. Blizzard issued a statement claiming they had correctly identified and restored all accounts and credited them with 20 days play. Warden scans all processes running on a computer, not just the World of Warcraft game, and could possibly run across what would be considered private information and other personally identifiable information. It is because of these peripheral scans that Warden has been accused of being spyware and has run afoul of controversy among privacy advocates.

Famous quotes containing the words warden and/or client:
“This was a great point gained; the archdeacon would certainly not come to morning service at Westminster Abbey, even though he were in London; and here the warden could rest quietly, and, when the time came, duly say his prayers.”
—Anthony Trollope (1815–1882)
“A client is to me a mere unit, a factor in a problem.”
—Sir Arthur Conan Doyle (1859–1930)
