Would there be anyway to make a module or something, that would be run before the real script/perl code is run?
Im admin at an ISP and i often see user-websites with bad PHP code getting hacked, and often this results in an upload of some perl-written bot to /tmp/ or /dev/shm, which is then executed.
What i would really like to do, is simply check if script-location is /tmp/, dont run the script. (sorta like a "trusted path execution" for perl)
But if there was a way to hook in some perl code to be run before the actual script, one could do a lot of cool stuff, like grepping the file for specific patterns, checking owner of file etc. etc. Could be fun to play with.
Is there any such pre-execution hook?
