If someone is able to hack into your site, they can alter your files to send them your customers information. I've seen this happen several times, thus the genesis of this contribution. This contribution will create a record of your files so that they can be checked at a later date. If any files have been added or deleted, or the size, timestamp or permissions were changed, you are notified via email. The script can be ran manually, but the best way is to set up a cron job so that the files are checked automatically.
This is a full package.
