First things first, nmap that bad boy and get yourself an operating system.
That's half the battle right there. Now I don't know off hand of any
exploits for the MS telnet server, but that's not to say that there aren't
Also try a google search for that prompt. I did a quick one and found a few
third-party apps for NT/2000 that give the "hello>" prompt. A third-party
telnet server just increases your chances of finding an exploit. Also check

Subject: Unknown Telnet server
Wondering if someone can help me out. My employer has asked me to do a
security test of their network, using ANY method I can to find holes in the
network. So far I have only one tiny hole. It's a Telnet server running on
someone's desktop computer which has a hole through the firewall. However,
I have no idea what Telnet server it is, and if there are any exploits that
I could use against it. The only thing it does is, when I connect, says:
Anything I type disconnects me, but I can connect over and over again.
Any idea on what type of Telnet server that is? Chances are that it is
running on Windows NT 4.0 with SP6, but it could be on NT server or (slight
chance) 2000 Server.
Also, does anyone know of a brute-force password guessing tool I could try
and use against it?
