According to a report by Panda Software, two new trojans have appeared on the internet recently which take advantage of Microsoft's Windows Media Player using DRM (Digital Rights Management).
Trj/WmvDownloader.A and Trj/WmvDownloader.B are both spreading through P2P networks and in video files. The trojans take advantage of DRM by attempting to obtain a licence for the video file. The video files infected by these Trojans have a .wmv extension and are protected by licenses, supposedly issued by the companies overpeer (for Trj/WmvDownloader.A), or protectedmedia (for Trj/WmvDownloader.B).
If a user downloads a file which is infected the files pretend to download the licence from certain web pages. Unfortunately they redirect the user to internet sites which hold adware, spyware and dialers. Panda software is currently protecting users against these latest trojans. It's thought that files on P2P networks such as KaZaA or eMule are mainly affected.
