Microsoft Corp said portions of its Windows source code the tightly guarded blueprint of its dominant computer operating system had been leaked over the Internet.
Microsoft spokesman Tom Pilla said in an interview with the Associated Press that some incomplete portions of the Windows 2000 and Windows NT4.0 source code had been ‘‘illegally made available on the internet.’’
Access to the source code could allow hackers to exploit the operating system and attack machines running some versions of Windows. Several versions including the ones containing leaked code, are used on millions of computers worldwide. Such access could also provide edge to rivals, who would gain understanding of the workings of Microsoft’s technology.
