At SONY BMG Music Entertainmet you can find a list of 52 Compact Discs recently released by Sony Music that contain Digital Rights Management software (DRM) called XCP.
When one of the discs in question is inserted into a computer software is installed without the user’s permisssion which introduces severe security holes. Sony’s XCP software transmits information about your listening habits across the internet (contrary to even it’s own license agreement), and virus and trojan writers can exploit the software to destroy your system. The software is difficult if not impossible to completely remove and as a result Sony is now facing seven lawsuits, including this class-action suit from the Electronic Frontier Foundation.
Another nudge in a movement away from Compact Discs?
