Xpose is a simple but effective shell scanner I've coded in Perl a couple months ago. You simply point it to a directory and it scans each and every file in there (including subfolders) and gives you an output of files that may have malicious code in them. Could be very helpful to run it on your server after one of your sites have been hacked, or you suspect that your server may have been comprimised. Malicious shell scripts are a common method used by a lot of script kiddies (no I'm not gonna call'em hackers) to hack. My script is able to spot most of the malicious shells that are out there.
