Warden (software)
Warden (also known as Warden Client) is an anti-cheating tool integrated in Blizzard Entertainment games such as Diablo II (since patch 1.11), StarCraft (since patch 1.15), StarCraft II, Warcraft III (since 2009-04-14, patch 1.23) and most notably World of Warcraft. While the game is running, Warden uses operating system APIs to collect information about certain software running on the user's computer[citation needed] (specifics outlined below) and sends it back to Blizzard servers as hash values to be compared to those of known cheating programs or simply as a yes/no response (whether a cheat was found).[1] Some privacy advocates consider the program to be spyware.[2]
Warden now scans Warcraft game memory space only, with exception of a few tools.
The things Warden currently looks for in-process includes but is not limited to:
- Model edits.
- Known cheat modules (DLLs)
- Known modifications to game functions
- Known cheating addons
- Speedhacks
- Known API hooks from cheats
The things Warden currently looks for out-of-process includes but is not limited to:
- Known cheating drivers (rootkits)

[edit] Operating Systems
World of Warcraft can be played on both Macintosh and Windows systems, but it was thought that only the Windows version had a full Warden client. On 23 June 2010 Blizzard updated the Warden Anti-Cheat Platform to version 2 - named Warden 2.0 - with World of Warcraft Patch 3.3.5.
WoW can be run under Wine on Linux. Warden currently detects whether it is running under Wine so it can modify its behavior slightly, though it remains fully functional.[citation needed]
[edit] Privacy Concerns
The Electronic Frontier Foundation and other groups have labeled Warden as spyware.[3] Blizzard has said that Warden does not gather any personally identifiable information about players other than the account being used. It also states that the data collected is only used for finding evidence of malicious programs and cheating.
[edit] Moderation & Chat Bots
"Moderation Bots" are third-party game clients written to monitor, administer, or moderate in game chat channels. While they are not used for cheating, Warden still disables them. Blizzard's stance on moderation bots calls them "Third-Party Programs". Many clans on Battle.net use moderation bots to keep the clan "channel" open at all times, and to allow multiple users to moderate the channel.[citation needed]
"Chat Bots" are third-party game clients that allow users to log into battle.net to chat with users or idle in the channel of their choosing. Warden still disables Chat bots to for the same reason as Moderation Bots.
[edit] MDY Industries v. Blizzard Entertainment
Warden has been brought to light by Blizzard's lawsuit with MDY Industries, LLC., the creator of the gameplay automation software Glider (more popularly known as WoWGlider or MMOGlider). Blizzard has alleged in legal filings that Warden prevents players from creating unauthorized copies of the game client[citation needed], which was previously an unknown function. Blizzard makes no mention of its known function of collecting data on open programs. Furthermore, it is actually referred to as "Warden," the first time Blizzard has confirmed its name.[4]
Presiding Judge David Campbell ordered against MDY in July, carrying Blizzard’s infringement claims and that the third party program tortiously interfered with World of Warcraft's sales and impacted Blizzard's relationship in a negative fashion with their customers. The US district court awarded Blizzard $6.5 million in damages against MDY Industries, and have held Donnelly personally liable for the awarded money.
MDY appealed the ruling to the Ninth Circuit Court of Appeals,[5][6] which heard oral arguments on 7 June 2010.[7]
On 14 December 2010, the Ninth Circuit vacated the summary judgment with respect to the secondary infringement count and the DMCA circumvention count with respect to the static literal elements of content already present on the user's hard drive, but upheld the summary judgment on the DMCA circumvention count with respect to the dynamic nonliteral elements of content provided by the World of Warcraft servers. The summary judgment on the count of tortious contract interference was also vacated, but was remanded to the District Court for further consideration as a finder of fact.[8]
[edit] Legal Notices
Legal actions have been taken up against Blizzard's RAM scanning, for privacy reasons, as far back as its first implementation - in the World of Warcraft alpha test, to watch if users were breaking their confidentiality contract. Within days of the beta test new lines were added to World of Warcraft's EULA.[citation needed]
