ust a week ago on Christmas, the massive Distributed Denial of Service (DDoS) attack from the notorious hacking group Lizard Squad knocked Sony’s PlayStation Network and Microsoft’s Xbox Live offline, but as if it wasn't the end of disaster for Microsoft.

 

This time it isn't a case of services being taken down — instead, the software development kit (SDK) for the Xbox Live is being freely circulated over the Internet. Another group calling itself H4LT has apparently managed to leak the Microsoft’s official Xbox One developer SDK, potentially opening the door for homemade applications and allowing unapproved developers to create unofficial software for the system.

 

The group announced the Xbox One leak via its official Twitter account, and also provided some screenshots of the November’s release of the Durango XDK (Xbox Development Kit) files, including the accompanying development tools, device firmware and its documentation.
