Report submitted to SARC:

"A window may pop up "RPC Call service has ended, Windows will reboot
in 45 seconds", new file created msblast.exe This is a new virus file
that you do not have in your databases yet. I run liveupdate everyday.

"The Remote Procedure Call service RPC Has ended, Windows XP will
reboot in 45 seconds, please save any open documents"

Error window shows up. Following this the system reboots itself.
I tracked this event to a stange file msblast.exe, created by an
unknown process a few minutes before. (11 Aug 2003)

I quarantined msblast.exe but as I was writing this text to you the
first time around I also received a "Generic Host Process for Win32
Services has encountered a problem" and a reboot occured.

I was fighting with the hacker who could see that I was about to
submit his file to SARC.

Converted to .txt file, this line can be seen in the jumble:
"<1@€öíÿmsblast.exe I ju
waníÿÿÿto say LOVE YOU SAN!! billý·mûgates&h d%you
makeÚÖ~»1hipossiQ
?"

A few weeks ago my machine was also hacked with the same error message
"The Remote Procedure Call service RPC Has ended, Windows XP will
reboot in 45 seconds, please save any open documents"

back then the backdoor.sb.gen virus was detected, this maybe a new
strain.

My friend and my Ex-wife's computers have been infected by this worm called
"LovSan". Basically it takes advantage of a security hole in Windows XP Pro
and Home and causes the infected machine to launch an attack on
windowsupdate.com. What the user sees is the aforementioned RPC message.
Problem is that the fix is a security update located at the Windows Update
web site. The time it takes to update your system is probably going to be
longer than it takes for the RPC message and reboot to occur. I have tried
a system restore with no success. I also tried removing all references to
MSBLAST.EXE from the system but this causes the system to become unstable.
I am currently trying collect the appropriate update files for this specific
vulnerability and put them onto a floppy or CD so that I can update their
systems in the short window of opportunity "LovSan" allows. If this doesn't
work then the next step would be to do a clean install of the OF/S.

The only article I have found so far about "LovSan" is on The Age (an
Australian News Portal) web site

Personally I got round the initial problem of getting online by doing the
following (Windows XP, sorry I don't know about any other OS)
Start - Control Panels - Administrative Tools - Services - Remote Procedure
Call (RPC) - Recovery (change all drop down menus to Take No Action) - APPLY

Apparently system restore won't be effective unless you switch off system
restore before you get rid of the virus. If you don't the virus hides in the
system restore and just pops up again later.
