Microsoft - it's a blast                                                                       August 2003

New worm targets latest versions of Microsoft Windows

Yet another virus has wormed its way into the world's most popular operating system, this one aimed at launching a denial of service against Microsoft's own servers.

MSBlast currently only affects Windows XP and 2000, although later versions will probably also affect earler versions of the OS. These releases are currently vulnerable because they use the Distributed Component Object Model (DCOM), and the worm does not spread by email but by scanning for openings on port 135 on an unprotected machine.

The virus contains the message 'I just want to say LOVE YOU SAN!! bill' and affects the registry with the following key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\
Run "windows auto update" = msblast.exe
This means that the worm runs automatically every time Windows is started. The denial of service was due to begin in mid-August and hit the Windows update service, but Microsoft has since changed the domain entries for this site.

The company has also launched a patch to update the security flaw in Windows 2000 and XP, and sites such as Network Associates contain information on the virus and how to remove it. To check whether you have been infected, hit Ctrl-alt-del and, under Processes look for an entry for MSBlast.
