    I think i saved all of them….
    I deleted the hackers user from users

    will that prevent him to login back in?
    How could he attack all WP sites on my server?
    I also updated all sites, plugins….and changed passwords for admin…

    If you have a user named “admin”—

    Do not use the default “admin” username on a WordPress site. Hackers know that WordPress ships with that and will try brute-force methods to get that user’s password.

    If you have a user named “Admin” create a new user, make the new user an administrator, assign all the “admin” posts and pages to the new user, and then delete the “admin” user.

    The resources Jan provided are good ones. Read them, make sure you understand them, ask questions when you don’t.

    Installing WordFence is a good idea. Also, make backups of your sites regularly, and store them either on another server, or on a non-publicly accessible part of your server (i.e., above the public-html directory). That won’t stop everybody, but it will slow a lot of them down. Or just download them if they aren’t huge.

    is there a plugin to change username?
    I have read there is database query to change the admin to something else

    which backup is the best that downloads to dropbox, files and database?

    Just some words to the wise…as I see this type of situation occur nearly every day.
    In 2018, segregation of your WordPress sites is one of the top 3 best keys to security.

    Since it only takes one outdated “something” to allow hackers access to all of your websites, I strongly suggest you not host more than two WordPress sites on any shared account.

    The more WordPress sites you host in a shared account the greater your chance you’ll be mass hacked in this way.

    Analogy-wise, have you ever heard the term “Herding Cats?”
    Because each WordPress installation is composed of thousands of “cats” the more cats you herd into the barn the harder it’s going to be to herd them back into the barn if they get out… At the moment your “cats” are currently scurrying about outside the barn. And you are attempting to herd them back in.

    Once a site has been compromised, there are literally hundreds if not thousands of ways your hacker may be able to re-access your account. Simply changing passwords or removing obvious hacker users will not solve “the problem.” All are you doing is attempting to curb the symptoms of the attack. It’s likely they’ve placed backdoor scripts through your account at this point.

    It might actually be smarter at this point to move some of your accounts off to a separate account, then harden each as best you can.

    At least that way if your account is hacked again, you’ll have a better idea which one was the entry point, and you’ll reduce the likelihood all your sites will be hacked again.

    Why Drupal sites are harder to crack?
    WHy always wordpress?
    THere should be default state to automatically update all the plugins and core wordpress when it comes out…
    Putting 2 sites on each server? That is very costly! Very costly
    Yes I was cleaning up files on my server all night…..
    Now I put sucuri and wordfence on each WP installation, lets see what happens…..

    The benefits of open source content management systems like Drupal and WordPress is the exponential growth potential both user and developer wise (i.e., lots of people can improve it faster). That said because the underlying code is open and so many people are involved in writing their own code, there is no single set of perfect security coding practices that everyone follows.

    Human beings make mistakes and “hackers” will try to take advantage of coding errors or techniques they learn to exploit weaknesses in the code. it’s what they do.

    So in answer to your question, Drupal is no more “harder to crack”. Any open source coded platform like Drupal, Magento, WordPress, et al, all have the same weakness if you will in regard to potential exploitation.
