Hello.
Recently I noticed that I had a process running
with which I was not familiar. scrgrd.exe
I searched my registry to find it's key and
It was listed as "Microsoft Restore".
I installed a firewall and it caught scrgrd.exe
trying to access the internet and that was
when I knew that something was wrong. The file was
under c:\windows\system32 and it had more than 1
registry initialization keys:
[Software\Microsoft\Windows\CurrentVersion\Run]
[Software\Microsoft\Windows\CurrentVersion\RunServ
ices]
[...]
The file was upx packed. It was also hidden, system
and read-only. I upx-unpacked it, and viewed it with
a hex editor. It contained strings which indicate password-collecting functions and file-transfer functions. It also contained SQL functions like SQLDisconnect, SQLExecDirect, odbc32.dll etc.
Other functions it contains are DeleteService , StartServiceA, etc. e.g. Windows Services manipulation.
The program also seems to create msdos batch files for scanning IP's.
"@echo off
:repeat
del "%%1"
if exist "%%1" go to repeat
del "%s" %sdel.bat
"
One of the string is "\\192.168.1.210\IPC$"
It is written in Microsoft Visual C++.
References to "ARP cache", "DNSFlush", "PSNIFF" might indicate
ARP-poisoning and/or sniffing abilities.
A really alarming feature is some IRC commands along with the string "paypal.com". It is certain that
this [worm? trojan?] works as an IRC bot.
It also has screen-capturing and key logging abilities:
"[CAPTURE]:Screen capture saved to: %s"
"[KEYLOG]:Keylogger active"
"rlogin","rloginstop" and other references to rlogin
indicate that an rlogin server might be an option too.
It also contained critical registry values
like "Software\Activision\Soldier of fortune II" and
many other game registry values where the games store
their serial numbers. Obviously the program collects
them and sends them to it's creator.. [Over IRC?]
Finally some suspicious strings contained are
{beagle1
beagle2
mydoom
MyDoom
lsass
netdevil
sub7}
etc..
Another interesting part is:
"Connected to %s
3.72.0.0 131.131.131.131 netninjaz_place 12/12/04 13:13:13 netmaniac was here neTmaNiac""
Could this be a time trigger?
Other wierd strings include "MEOW" all over the place
and \\ \C$\123456111111111111111.doc"
The program also has the ability to set up and delete network shares.
There is also a small dictionary of something,
most likely names.
To sum it up - I think this is REALLY big.
It contains most of the tricks in the book
and nobody has nothing on it yet.
[I googled it for "scrgrd.exe" and nothing was found]
This requires urgent attention IMHO, unless it is already known.
Thank you for your attention,
Anastasios Bitsios
