This is a variant of the "sebd" backdoor.  

Its pretty much the original, but had some fixes done by someone (apparently kingcope).

I'm putting this up here, because its being abused by cheeky script kiddies to be a pain in the ass or some shit.  

Original readme is below.

sebd v0.1 (simple encrypted backdoor)

sebd is another linux backdoor.

what does sebd provide:
- a raw sniffer
- aes encrypted shell
- full tty/pty support
- connect back (bypass moust of the firewall's)
- does not open a port
- you can log in on any opened port
- cleans the logs (wipes out the ip from where the sniffer received the password)
- tcpd function (if the pasword is from an ip that isn't in the list -> no shell)
- password is encrypted with DES (hardcoded only in the server binary)

usage:

on the server host run: ./sebd
on the client host run: ./client -h host|ip -d port
