It sounds too me that you have a malicious user on your server and if so, fire them. If you suspect you've been hacked from externally, then I would format and re-install -- or use a backup from a known good date. I've been coding PHP since 1996, and have NEVER heard of a man-in-the-middle attack like this. It just sounds like you have other problems and this isn't a solution, it's a band-aid. http://daevid.com
