Dark Shadow

Ok this is a real brain buster .. its not on my puter its a friends .. as soon as she logs on the internet ( well we are still testing this ) somewhere along the way boom its starts her NIS 2002 starts flashing and is getting probed from all over . ie vancouver bc canada , new york , taiwan , vaginia , and its always Dark Shadow trojan ( back door ) .. ok so NIS blocks this of course and after a port scan NIS blocks all incoming for next 30 minutes ... but of course I need to find out why? I have run a full system scan ( anti virus NAV 2002 ) I have ran full scan with The Cleaner 3 ( trojan proggy ) have not found anything ? This is very annoying to say the least ... trying to narrow it down as best I can by lets say connecting and not going anywhere ... then I will ask her to open icq ... wait a while nothing ...next open msn messenger wait a while ... you get the idea yes I am thinking someone might have her as a target and when she logs onto a certain program maybe thats where it starts?

Ok so for now any input on Dark Shadow will be of help to me

I will keep this updated as I troubleshoot later today

thanks in advance for any help
Name: Dark Shadow
Aliases: N/A
Ports: 911
Files: Darkshadow.zip - 87,119 bytes Darkshadow.trojan.exe - 180,321 bytes Winfunctions.exe -
Created: Match 2000
Requires: N/A
Actions: Remote Access
The trojan is encrypted.
Versions: N/A
Registers: HLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices \
Notes: Works on Windows. Password = UHA. Compatible with the Back Orifice server.
Country: written in the USA (??)
Program: Written in Turbo Pascal Encrypted.


First click Start, and go to Run. In the box, type regedit and click OK.

When regedit starts, you will see a file-like tree on the left hand panel. Open the folders to follow the path:


Click on 'RunServices' and the righthand panel will change.

Look for an item titled:

winfunctions="winfunctions.exe" and delete it (Right click and choose delete)

Close regedit and reboot your computer to remove the trojan from memory.

Now you can use explorer to go to C:\windows\system\ and delete the file 'winfunctions.exe'

Your now disinfected!


Enjoy :) Hope it helps.

Thanks nick

But strange as this sounds I went through that last night and never found the so called reg entries or .exe

So I am wondering is it possible there is another variation of this?

but thanks for taking the time to help.

I dont see any strange reg entries under


which is what is bothering me because I cant see why her computer is getting probed and I even think I saw ( need to read the logs later again ) her computer sending out or attempting to send out to an unknown ip... ok so again thanks and I am still looking .....
Allright, now that's strange. I know it's a bad suggestion, but I could just clean install windows. Then again, it's no big deal for me, I just did it yesterday, but for others it may be a pain.

I looked for variations of dark shadow, couldn't find a thing.

However " dark avenger " comes in about 50 different flavors, sure this isn't the name? I know it's a stupid question.

No such thing as a stupid question !

And of course if needed I will do the full format / clean install

but I like a challenge LOL and yes I saw lots of info about the dark avengers ...ok so for now I am going to keep troubleshooting to see if I can narrow it down to an appliction ie IRC , ICQ, MSN messenger... if not I dont see how I will find something that NAV2002 fully updated and The Cleaner 3 does not find ... so again thanks for the help and I will get back with info if I do find something .......:eek:
Sure, glad to provide useless known information :p

Really though, I'm curious, once you get to the bottom of it, post and say what it was :)
