Microsoft filed a federal lawsuit against the creator of FairUse4WM, a program that removes the DRM code from Windows Media files.
The hack, titled FairUse4WM, tackles the media player's infrastructure that identifies music or videos that have been tagged with a special anti-copying code. Subscription music services, like Napster and Yahoo Music, are among the most well-known users of this technology. Without DRM attached, users are able to make unauthorized copies of the songs.
Microsoft released multiple patches that counter what the FairUse4WM software did, because the fast-acting hacker was quickly able to update the hack to circumvent a new patch.
