Another group calling itself H4LT has apparently managed to leak the Microsoft’s official Xbox One developer SDK. The leaked software development kit (SDK) for the Xbox Live is being freely circulated over the Internet. The group says the leaked SDK will allow the community to reverse and open doors towards homebrew applications being present on the Xbox One. There is no definite exploit at the moment that would allow developers to run homebrew applications on the console, but the group does hope that someone familiar with the inner workings of Windows 8 will be able to dig through the files.
