First shutdown all website.
Did the hacker change the file content or only the website output?

First place I would check is the FTP logs. If the files where altered though FTP change FTP passwords, restore sites from your backups and also change database password afterwards.

That and if the FTP is not encrypted, that's almost 100% the problem. Never use FTP that is not encrypted.

There's really no chance that this has anything to do with CI.

It could be anything:
- sql injection
- without file check, the hacker could upload anything. eg. youurl.com/upload/badphpfile.php
- misuse of shell_exec
- backdoors from a former employee
- old plesk, old phpmyadmin
- old server version

Are the 80 sites on the same server?

Make sure that you also flag your index.php with CMOD 0644

You should move your ./application and ./system folder to the root.

A long time ago I had this happen. I wanted to blame all of the usual suspects, but in the end I found that it was my use of plain FTP, and the fact that another computer on my network was infected with many viruses / malware. I even changed my password to FTP, but that didn't help because that other computer was sniffing network traffic, and as soon as I used another password it would grab it.

OP never said if he/she was using plain FTP. What is it OP? Ideally use SFTP, FTPes, or anything besides plain FTP.
