The digital rights management (DRM) security used by Microsoft to protect apps in its Windows Phone 7 Marketplace has been cracked, enthusiast blog WPCentral reports. Though the technology needed to do so is not yet in the hands of the general public, the DRM protecting paid applications can now easily be stripped off of apps. If details of the vulnerability used to achieve the DRM crack are made available to the public, unscrupulous programers could use the exploit to develop software that allows users to steal applications and deploy them to Windows Phone 7 devices. Microsoft has not publicly responded to the security hole, though WPCentral claims the company has been made aware of the issue. Hit the break to see Microsoft’s Windows Phone 7 Marketplace security being manhandled in a proof-of-concept video demonstration.
