    It’s also worth mentioning that some hackers will not modify their files, but instead alter your database. I’ve worked with people who have had entries in their database changed to redirect to different URLs. For instance, one person had the post_title of every entry in their posts table changed to a redirect so any almost page load would cause the site to redirect. Another had an entry in their options table that was the actual HTML code that displayed, so rather than sticking it in a file like index.php, they put it in the database. This made finding the problem harder because you don’t expect that as much as a file hack.

    Great point! Thank you for the comment.

    That’s something I personally haven’t met during my daily maintenance job on client’s sites. But I know it is no doubt hard to deal with in that case.

    It was also when I realized the possible “database hacking”, I changed all the database backup schedule to daily, even twice a day on some sites.
