posted a detailed step-by-step guide on how to "compromise [the] Windows 8 [Metro] games revenue stream."
Using the Soulcraft Windows 8 game as an example, Angel's post shows how Windows 8 users can edit parts of a game to bypass actually paying for in-app purchases.
Angel's post also shows how Windows 8 users can modify trial apps, giving them a full license, including a way to remove in-app ads.
One way to fix this issue would be to have developers build two app packages (one limited functionality trial package and one full functionality package) and have those secured by the Win8 store purchasing system.Notably, the post has become so popular that his server is currently offline.
With the hack, it's only a matter of time before some enterprising developer creates a one-shot tool that unlocks every in-app purchase, pirates trial apps, and removes in-app ads.
The issue isn't with Windows 8 per se, but with any app that installs to your hard drive. That's why, often, apps will check back to the Mother Ship to determine the authenticity of an installation.
