Windows Phone 7 Marketplace Digital Rights Management (DRM) Security Gets Cracked

The Windows Phone 7 platform has been widely appreciated following its initial launch, and has gained a considerable share in the smartphone market worldwide. Earlier this month, the official sales figures of Windows Phone 7 devices were released and they show a promising future for these devices, however as any particular
device gains popularity, the more interest the hacking community develops in it. Previously, we reported about a tool called ChevronWP7 which allowed users to unlock their Windows Phone 7 device and run sideloaded apps on it, now it has come to our attention that the digital rights management (DRM) security that Microsoft uses to protect apps in the Windows Phone 7 Marketplace, has been cracked. More details given below.


According to a report published by WPCentral, a proof of concept program has been developed that will successfully download and crack any application found in the Windows Phone 7 Marketplace.


However, it should be noted that this particular technology has not been rolled out to the general public; this is just to show that the DRM protecting paid applications can now easily be stripped off of apps. Considering the fact that if details of the vulnerability used to achieve the DRM crack was given out to the general masses, devious programmers could use the exploit to develop software that allows users to steal applications and deploy them to Windows Phone 7 devices.


Microsoft has not made any comment on this security hole, though WPCentral claims the company has been made aware of the issue. Watch the proof of concept video below to see for yourself how the Windows Phone 7 Marketplace security is breached.
