A compromised website can also happen if someone who has access to the site’s backend logs in using their own credentials and then changes the content without authorization.

Hackers typically have two goals when compromising websites:

1) to use your website for their own purposes (such as sending spam emails from it) and/or

2) to sell access to your website for profit.
