That's interesting... how to do it?
Telnet is echo'ing back response. You can turn it off locally.Any idea why this occurs? It only does it if I telnet, not if I use netcat to connect.
Great, I was able to turn it off locally like you said. So I booted up my XP box to see if the registry file was just a Vista thing and it didn't work on XP either, so something is wrong. I've tried it with both telnet, nc and through meterpreter handler and none of them are working.
Well after some trial and error I figured out what issue with the registry, it seems that I forgot to allow the program through the firewall first before I tried to insert the registry key, go figure.
If your are familiar with meterpreter you can try this phreedom.org/software/metsvc/
I just LOVE that packetstorm paper on modifying files... never though of that solution, always though you need to either pack the file or recompile the source...
