Latest update: 19-8-2003: W32/Nachi.A virus
URGENT ALERT - MSblaster.exe
There is a new trojan virus around
spreading around quite fast. If your Windows
XP is closing down all the time without a reason you can have this virus
on your pc.
When the virus is active and you go
online you will get this message:
To check press control+alt+del button to
see the tasks operating on your
machine, if msblaster.exe is active you are infected.
Also check Windows/System32 directory for a file called msblaster.exe
W32.Blaster.Worm is a worm that exploits
the DCOM RPC vulnerability (described in Microsoft
Security Bulletin MS03-026) using TCP port 135. This worm attempts to
download the msblast.exe file to the %WinDir%\system32 directory and then execute it. The
worm has no mass-mailing functionality.
The worm also attempts to perform a Denial of Service (DoS) on the Microsoft Windows
Update Web server (www.windowsupdate.com). This is an attempt to prevent you from applying
a patch on your computer against the DCOM RPC vulnerability.
