Last week, the source code for MS Windows XP and Windows Server 2003 OSs were leaked online. Now a Windows developer that goes online with the moniker NTDEV announced to have successfully compiled both the OS and Server 2003 using the leaked source code. The developer also published a video to show how to compile both Windows operating systems. The leak could allow threat actors to search for zero-day issues that could be exploited in attacks against the tens of millions of PCs still based on the popular Microsoft OS.”]
