csrss.exe and SYSTEM.EXE mysteries...

Hi gang,

I have a dual boot 98SE Lite and XPSP3 system. I use 98SE Lite
99.9% of the time. (Let's not get into a discussion of this,
please.)

Two peculiar things happened recently on my XP partition and on
my external USB drive, seemingly unrelated except that they
happened about 10 days apart and I have only gotten one other
infection in over 20 years of doing this.

I should mention that I have the XP partition although I hate XP
and almost never use it. I have it ONLY because of a piece of
hardware which only has XP drivers. Also, another advantage of
having it is that I can run MBAM.

A few days ago I thought it might be time to do an MBAM scan, so
I did. As usual, it found a few minor things (like the fact I
have the Windows Firewall off and do not wish to be informed of
this every time I boot into XP), and one which was not at all
minor - 3 copies (well, it actually listed 3 "memory processes")
of a file called csrss.exe in "Documents and Settings" - NOT the
file which is in the System32 directory. MBAM said it was a
"Trojan.Agent", I let it delete the file and that was that. No
ill effects were observed.

Specifically, the report says, 3 times with a diff. #:

Memory Processes Infected:
e:\documents and settings\admin\application data\csrss.exe
(Trojan.Agent) -> 1336 -> Unloaded process successfully.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows
NT\CurrentVersion\Winlogon\Shell (Hijack.Shell.Gen.A) -> Bad:
(Explorer.exe "E:\Documents and Settings\admin\Application
Data\csrss.exe") Good: (Explorer.exe) -> Quarantined and deleted
successfully.

The date of this file was July 14 2011.

There was also this:
HKEY_CURRENT_USER\SOFTWARE\VB AND VBA PROGRAM
SETTINGS\Micronsoft (Malware.Trace) -> Quarantined and deleted
successfully.

and

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
\MSWUpdate (Trojan.Agent) -> Value: MSWUpdate -> Quarantined and
deleted successfully.

(Since I never go on the net with XP, I have auto updates turned
off, I don't know what else to say about this.)

I Googled for Micronsoft and got almost nothing except for a
tiny Indian site with some desi actress photos and a few semi-
nasty programs (a crack downloader, etc.) which I have never
seen before.

HOW the csrss.exe file got into the XP partition is a mystery,
since I do not go on the net with XP and I have not installed
anything (let alone a cracked program from a suspicious source)
on the XP partition in months. The main drive with its C
partition with the trusty 98 SE Lite was fine - nothing found.

As usual, I did not bother scanning the other partitions with
MBAM since they only contain data and since I work with them all
the time I would have probably noticed anything strange.

OK, that was more or less "normal", although a little baffling
(as in "where did it come from since I do nothing on that
drive"). I suppose I /did/ do /something/ but never noticed
anything wrong and forgot whatever it was that I did.

Now for the really strange part.

After doing the above, I rebooted into 98SE and switched on my
external USB drive. (It is actually just a regular drive I've
had for several years which I recently put into a $15 USB box. I
use it mainly for data storage/backup, and do not switch it on
every time I use the computer. It works fine. It actually works
better under 98SE Lite than under XP - in XP it gives me one
partition twice, and the partition order and letters are always
totally messed up. Whatever. XP /is/ better, right?)

Everything was fine.

However, when I switched on my USB drive yesterday, I instantly
noticed that EVERY PARTITION on the USB drive had two new files
in its root:

Autorun.inf
SYSTEM.EXE

Both with hrs attribs, and both dated July 23, 2011. I am
99.9999% sure they were not there when I was in XP and ran MBAM
on that day.

The contents of the autorun.inf file are as follows:

[autorun]
shELlexEcUtE=sYStEM.EXE
;
ICON=%WInDir%\SYsTEM32\sHeLl32.DLl,4
;
actioN=Open folder to view files Using explorer
;
shelL\OpeN\coMMAnd=SYSTEM.EXE
shELL\explore\COmmaNd=SYSTEM.EXE
UsEautOPLaY=1

Rather than booting into XP just to see what would happen ;-) I
thought I'd take the cowardly way out, and removed the hrs
attributes of all the files (I have 11 partitions on that drive,
so 22 files total - let's not get into a discussion of
partitions, please), and deleted them. No problem.

I scanned the files with ESET and it informed me that SYSTEM.EXE
was a variant of Win32/Injector.HTF trojan. I also looked at
"properties" as well as inside the file and it contained the
name "jgk.exe" as the original file name, and a few other
things, like the author's name, which I have a feeling may not
be authentic ;-) (it's "Riordan Barton", FWIW).

While nothing /really/ happened, I am curious as to how these
two files got onto my external USB drive which is only used
occasionally ***while NOTHING happened to the main drive inside
the computer***.

And, of course, where they came from in the first place.

I think I may have booted into XP for about ten minutes on the
23rd, I'm not sure.

I don't know if this has anything to do with the fake csrss.exe
file which, according to MBAM, appeared on my system a few days
earlier (and is dated about 9 days earlier).

Since I was unable to find anything on the web, I thought I'd
post this story here. I would welcome any comments and
hypotheses, etc.

I have both files saved (renamed) if anyone wants to examine
SYSTEM.EXE or possibly even run it in Sandboxie or however you
guys play with these things.

(I apologize for the length of the post. I try, but I can not be
concise.)

All that you posted were malware. No doubt about that with the last being an AutoRun
worm.

No execxutables should be in %appdata%. They are there because you have full rights to
write there rather than limited rights (using LUA) in the %windir% folder.

I'll be glad to look at ant file you have; http://www.uploadmalware.com/ and report back
my findings.

I realize that, I just can NOT figure out how I got it. And the
USB drive getting all infected and NOTHING happening to the
internal drive with the 2 OSs on it?

I have 2 other LUAs, but the way XP is a completely different
machine for each user is one of the things driving me crazy, and
since I hardly ever boot into it, I just go as admin. Also, it
never connects to the internet.

Sure, if you feel it worth your while, take a look at
"system.exe" and see what it does. csrss.exe is gone, I had MBAM
delete it before it occurred to me to save it.

I will upload it as system.bmp unless there is another option on
the site.

Thanks for the reply.

Just out of curiosity (or it may be relevant) did you use NTFS at all or
were your intentions to use FAT32 so you could access your XP filesystem
with 98?

Do you have a router?

You've already stated that you have the xp firewall off, and
are not applying updates.

If you are not behind a router, and the network connection has
been set up in xp (even if you don't use it), the computer is
vulnerable to attack.

Was it "C:\" or "%userprofile%"?

His "E:\" should be an indication of what OS was running when the
infestation occurred if an environment variable was used. Sure looks
like he was running in XP not 98.
