 Brief History \
:
+----------------`----------------------------------------------------------
.
A friend mentioned the other day that he is seeing a connection is being
:
made to 64.240.175.18 on port 8989, every time he use Internet Explorer.
:
See detail below.
:

:

:
 The Problem \
:
+-------------`-------------------------------------------------------------
.
After I did work on the issue for some time I found a sypware kernel32 on
:
his machine.
:

:
How did I find the spyware?
:
+--------------------------+
:
I did run a port monitor application and Lunched Internet Explore and went
:
to google.com, sure enough when IE connected to google I saw two connection
:
one to google and one to 64.240.175.18 on port 8989 when I saw that I hmmed
:

:
Next I opened again IE but I did not connect to any site. (blank page).
Sure:
enough No connection to any site.As soon as I connect to any site I will
see:
a connection to 64.240.175.18 on port 8989.
:

:
After mapping the port to application running on these ports, I found that
:
IE is using port 8989 that is normal since a connection was made
:
to 64.240.175.18
:

:
Since i need seen that IP befor I decided to investigate more this issue.
:

:
I tried to search the registry for 64.240.175.18 but I was not lucky.
:
I tried to search all file on the hard drive for a string 64.240.175.18 but
:
still no luck.
:

:

:
Next I jumped to a hardcore methode :) using regmonitor and file monitor.
:
After running Regmonitor and filemonitor I lunched IE and connected to
:
www.google.com. Now I have a big log to go over... I made another coffee
:
and sat down and stat looking into regmonior/filemonitor.
:

:
Something got my attension kernell32.dll reference.
:
HKCR\CLSID\{C7ADE150-743D-11D4-8141-00E029626F6A}\InprocServer32\(Default)
:
"C:\WINNT\Downloaded Program Files\kernell32.dll"                           :

:
I search for that file in C:\WINNT\Downloaded Program Files but did not
:
find it. I continued looking at the regmonitor log and found something else
:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\
:
Browser Helper Objects\{C7ADE150-743D-11D4-8141-00E029626F6A}]
:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\
:
Browser Helper Objects\{EBCDDA60-2A68-11D3-8A43-0060083CFB9C}]
:

:
One of these key was used to lunch the trojan everytime you run IE.
:

:

:
At this point I run wget http://64.240.175.18/kernell32.cab
:
To my surprise the file was their So i got the file and loocked at it.
:
The kernell32.cab contain two files: kernell32.dll, kernell32.inf
:

:
Currently [2-2-2002] the file still exist on their site if you like to
:
grab it here is the url http://64.240.175.18/kernell32.cab
:

:
NOTE: The interresting issue is NORTON antivurs and the cleaner did not
:
delect any trojan in the kernell32.dll. But the file is acting like
:
Win32.Destiny trojan
:

:
If you search google for Win32.Destiny you will find the desciption
:
of Win32.destiny trojan. The same behavior apply to the file
:
located at http://64.240.175.18/kernell32.cab
:

:

:
[Extracted From

:

:
Win32.Destiny
:

:
Win32.Destiny trojan is a Dynamic Link Library (DLL) usually called
:
"kernell32.dll". The use of this filename is probably an attempt to hide
the:
trojan, as users may confuse it with the Windows system file "kernel32.dll"
:

:
kernell32.dll c'est le PUTAIN de fichier qui'il telecarge
:

:
The trojan registers itself as a "Browser Helper Object", a DLL which
:
attaches itself to every instance of Internet Explorer. Because of this,
:
 the trojan is loaded whenever a new Internet Explorer session is started.
:

:
The trojan connects to a machine on the internet on port 8989 and sends
:
some information about the local system, including the IP address and the
:
user's e-mail address. It also changes the following Internet Explorer
:
security settings for the "Internet Zone":

:
 The Solution \
:
+--------------`------------------------------------------------------------
.
Someone must contact the administrator of the site 64.240.175.18 and tell
:
him/her to rm the kernell32.cab of his/her site.
