Report: Blizzard Can Track WOW Users Through In-Game Screenshots

September 11, 2012 -

This story on Slashdot Games reveals that screenshots taken in World of Warcraft have secret watermarks that can be used by Blizzard to track users - particularly when they are engaged in behavior considered to be illegal or that violates World of Warcraft's terms of service.

The story began a few days ago when a World of Warcraft players noticed that there was an odd mark on a screenshot he had taken in-game:

New submitter kgkoutzis wrote: "A few days ago I noticed some weird artifacts covering the screenshots I captured using the WoW game client application. I sharpened the images and found a repeating pattern secretly embedded inside."

He goes on to say that he posted the image on Owned Core, where multiple people within that community researched and experimented with WOW screenshots. So what did they find?

That the watermark inside every screenshot taken within WOW includes "user IDs, the time the screenshot was captured and the IP address of the server" the screenshot source was on.

The author of the Slashdot post points out that Blizzard did not notify users in its terms of services that it had or would use the ability to track them through screenshots they take and post to the community.

While it is certainly a clever way to track bad actors who engage in everything from gold farming to hacking, it is also a fact that no one at the company ever disclosed.

You can read about how Owned Core users figured out that Blizzard had hidden these codes in screenshots here.

Why does the company need to disclose the fact that they can track you?  It's THEIR GAME.  Do people really think they can break games like that and not get caught?

..... Um, of course Blizzard can get that info, they run the servers.

This is OLLLLLD news it's been there since at least 2008 but recycling old stories seems to be the in thing lately.

While Blizzard has apparently been watermarking since 2008, this is the first I've read about it. Are you saying this has been in the news before?

Re: Report: Blizzard Can Track WOW Users Through In-Game ...

Not only is it old news but people can track users and alts anyway through the forum system.  There's even a chrome addon that can link forum alts to posters if they've posted before.

The fact that users have an account ID number isn't something we don't know about as it's used on the forum.
