Hi,
I believe my Unix server has been hacked somehow, some one every day inserts an iframe on my index.html page. I am not sure what to do about it.
But I want to write a cron job that will check the site every hour and send me an email if there is a change in the size of one of the files. anyone nows whats the best way to do it?

any help will be highly appreciated.

Thanks,
