How To Find and Remove
the Back Orifice Trojan
from your computer (1998 version)

Notes on bo2k (BO 2000) (July 1999 and following)

NOTE: This page was cloned (copied) by a cracker recently and placed at another URL in Geocities with a TROJAN program falsely labeled as Chris Benson's, BoDetect for download! (Fortunately, it appears that very few people IF ANY were fooled by the fake page before Geocities removed it.)

This page will always be located at (sub-dirs created MAR 2001):
< /homestead/Athens/6939/avt/bo/thebop.html >
which is (since YAHOO changed things after buying Geocities) the same as:
< /homestead/thestarman3/avt/bo/thebop.html >

The URL (location) can be verified by checking The Starman's PGP Public Key entry which is listed as:
The Starman <www.geocities.com/Athens/6939/Feedback.html>

So, if you see this page in any other location, please notify The Starman immediately (AND if the 'fake' page is found at Geocities, then please inform a Geocities volunteer too so they can remove it quickly).


This page contains:
  1. What to do if you found the Back Orifice server on your computer!
  2. Warnings about using the Back Orifice client or GUI
    (these are the parts of BO that crackers use).
  3. Links to other References about BO.
  4. How to Find and Remove Back Orifice from your computer.
    (Including my own REGCheck batch file program.)




Finding and Removing Back Orifice

Most likely you have what I am calling here the generic form of the BO program.  This is easy to find on your computer, if you know what to look for and where!


Checking for the Presence of the generic BO program

If you are a person who has absolutely no time at all or you feel that learning just one more thing about your computer will break your head, I have good news for you: a windows program that will autodetect AND remove BO from your computer. You should proceed immediately to my page about:
BoDetect by Chris Benson (CBSoftSolutions).


If you have any questions, you can write to me using this form.


  Before, you even begin reading about BO, make sure that
your Windows Explorer 's (or My Computer 's)
" View > Options... " menu is set as follows:

File Explorer: View, Options, View Tab


The quickest way to check for the BO server is in a DOS window:

If you've never used a DOS window in Windows™ 95/98, you should read this page: How To Use a DOS Window in Windows™ which explains everything about DOS windows.

Why does BO start running every time I turn on my computer?

When the BOSERVE.EXE trojan program was first executed on your computer, it placed an entry to itself in your REGISTRY file! This entry is located in a special key called the "RunServices" key which executes any programs listed there as soon as Windows™ 95/98 has loaded itself. There are a couple other keys like this in the Registry too. You can read more about them here:
Readme file for REGCheck.zip.

If you'd like to see a list of all the programs that are started from your Registry, you can use a batch file that I made for that. Just click on this link to download my program the package:
   REGCheck.zip   (only 7kb !)
This file comes with complete instructions (see text file above) on how to detect BO on your computer and being only 7 kb — makes it easy to email to your friends.

If you visit a friend in person to check for BO on their computer, you should also take a copy of BoDetect with you in order to eliminate BO immediately.


I may add instructions here in the future describing how to remove BO on your own [But this would require editing the REGISTRY file and REBOOTING your computer].
Therefore, I recommend that you download and use:
Chris Benson's BO Removal Program.




For those of you who are very technically oriented and are interested in seeing some of the actual client / server protocols of the Back Orifice trojan. Or, better yet, if you are a network programmer who is interested in using this data to trace those using the boclient, I've added this page about the BO Client/Server Protocols.

____________________

Technically, the BO program might be called a
remote client/server utility, but no one in his right mind would ever leave the "generic form" of a stealth program running on a computer unless he was just plain ignorant, or intended to do something devious with it!
As an aid to computer consultants, this could have been a very handy tool [in a different form], but the fact that BO's password capabilities and its encrypted UDP transmissions have already been cracked, makes it very dangerous to use. Even the client part of BO was found on occasion to be sending data back to its makers (see "pchelp's" website from my BO References page). So beware all you cracker wannabees! (Conclusion: BO is not safe to use for any valid purpose.)
There's really only one use for BO (and why it's being given away for free): to make it easy for all those (kids?) experimenting with invading other people's privacy to do the "dirty work" of its creators as they spread BO onto computers of unwary Windows™ 95/98 users. BO comes from a group (the cDc) that says they are disgusted with the lack of secruity in these MS operating systems, and that's why they wrote it. So, every time a twisted mind trashes a computer or steals information using BO, that message (among others !) is being spread.
WARNING! Many computers now run programs that will log pings on their Internet ports and record both the time and the IP Address they came from. If you use the client part of Back Orifice to search for BO servers, you may be subject to immediate removal from your ISP for such activity!   You have been warned.
