A "white hat" developer has posted video proof of a cracked Windows Phone 7 Marketplace, a loophole that allows users to download apps onto unlocked WP7 phones.
The video, pubbed on WPCentral.com, shows editor Daniel Rubino downloading a cracked app (Fandango served as test bunny) and transferring it to an unlocked WP7 phone through XAP Installer.
However, to many viewers' annoyance, he refused to show how he removed the app's security signature, an application he calls FreeMarketplace. Watch the proof-of-concept below.
Instead of promoting piracy, Rubino said he was trying to mobilize Microsoft to take action against the marketplace's security vulnerabilities.
"[Microsoft] has known about this for months already with little or no movement let alone acknowledgement of the problem. This isn't new. It's an attempt to bring focus and urgency to the issue," he wrote.
Yesterday an independent site said the Windows Phone 7 Marketplace has added over 5,000 apps since launching in early October, outpacing Android Marketplace
In November, Windows Phone 7 users were "treated" to the phone's first known jailbreaking tool.
