BBC Tells World About The Warden

Anonymous Cowpat writes "The BBC is running a story about the Blizzard title World of Warcraft. Specifically an article about, 'The Warden', Blizzard's highly-invasive anti-cheating software, which some, including The EFF have labelled as spyware. Most of the people around here have probably heard of it by now, but it's interesting to see the story in the mainstream press and (at time of writing) on the front page of the BBC's technology news section, no less." From the article: "The watchdog program, called The Warden by Blizzard, has been known about among players for some time. It makes sure that players are not using cheat software which can, for example, automatically play the game and build up a character's qualities. However, knowledge of it crossed to the mainstream thanks to software engineer Greg Hoglund who disassembled the code of The Warden and watched it in action to get a better idea of what it did."

      Point being, these kinds of tools are in demand, and there is nothing morally wrong with using them, other than a license agreement that says no -- you pay for the bandwidth to their servers, a log on, and the right to interact with their servers according to their well defined, well hidden within a beautiful graphical interface, protocol. The fact that Blizzard expects you to initiate all of those interactions manually with a human interface device is somewhat artificial to maintain some notion of 'fairness' within the game world -- which I certainly understand, by the way.

      I think these kinds of 'cheating' tools ruin the games, certainly, they take the fun out of it, and that's one reason I don't use 'em / don't write them.

    By definition, spyware sends back personal information concerning the user. Warden does no such thing, even going by the analysis of Hoglund (the author of a rootkit.com article, and a developer of cheat software for WoW). Hoglund uses FUD to scare the reader into believing that WoW is snooping around their e-mail addresses and IM friends list, but in actuality, the first thing Warden does when it scans a string is to hash it, thus removing all personally-identifiable information. It compares the hashes to a list of hashes sent from Blizzard's servers, and sends a notification to Blizzard if a hash matches one on the list. That's the only information it sends back.

    Yes, it does scan window titles, and yes, coincidentally, those window titles may contain URLs or e-mail addresses. But Warden only works with hashes of those strings and doesn't phone them home. The paranoid can easily close other windows while running WoW (or, for that matter, uninstall), but the majority of the game-playing public wants anti-cheat measures in place.

    Note that this anti-Warden crusade is perpetrated by people who will benefit financially if Blizzard is humiliated into discontinuing the use of Warden. The folks over at WoW!Sharp, the most well-known cheating/botting program for WoW, were selling subscriptions to their software, right up to the point where Warden caught them using their cheat software and led to them being banned.
