 * Hi,
 * I noticed one of my sites had the alert that the database has changed. I’ve seen
   this before when we changed passwords.
 * However this time, none of us changed the password. It seems that the username
   for one of the admins was changed to:
 *     ```
       Admin ID: 1
       -user_login: AnonymousFox
       ```
   
 * Does this mean someone managed to bypass the sql injection filter?
 * When I looked at the logs, it doesn’t seem to show any critical or high during
   that time.
 * I also ran NinjaScanner and it doesn’t find anything wrong.
 * My site allows public users to upload files and information via a form setup 
   with Elementor. Not sure if this is related.
 * I’ve also set in NinjaFirewall to disable code execution in the uploads folder.
 * I am wondering if we can track how it happened?

 * Did you check this discussion, you may have a similar issue:
    [https://wordpress.org/support/topic/sql-injection-passes-through-firewall/](https://wordpress.org/support/topic/sql-injection-passes-through-firewall/)
 * Change your database password ASAP, and make sure the DB is not remotely accessible.
   If there’s nothing in your logs, it’s likely that they access the DB directly.
   If you have other sites installed on this account, they could access the DB from
   them.

 * Thanks for the advice. I checked and it looks like the database cannot be accessed
   remotely. The hosting is on VPS with WHM/cPanel. There are other sites hosted
   in the same server but in their own cPanel accounts. I believe cPanel has their
   own jailed environment to isolate the different accounts. The site having this
   issue is on its own account an no other sites are sharing the same cPanel account.
   Other than the database change mentioned earlier, scans didn’t find anything 
   and the site looks ok.
 * The client does have access to the cPanel account but I am not sure if that may
   contribute to the issue since the database can only be accessed via localhost.
 * I’ve updated the salt keys and also changed the DB password. Will monitor to 
   see if any issues.

 * Check if you can access the `/home/[username]/.lastlogin` file, it will show 
   you the last connections to your `[username]` cPanel account. Changing its login
   password would be a good idea.
 * Have you been hacked lately, before you installed NinjaFirewall?

 * > Have you been hacked lately, before you installed NinjaFirewall
 * Nope, this is the first. The site was deployed with Ninjafirewall from a fresh
   install so I believe its protected from the start.
 * I was able to access the .lastlogin file. There are only 5 lines in there and
   the IPs belong to mine and the client.
 * Anyway, the issue just repeated again. The database password got changed which
   was detected by Ninjafirewall. And this time there was also a malicious file 
   in the root folder named uploads.php. The site turned into a file manager / webshell
   when I visited it.
 * So I had to move out all the files from the root folder and reuploaded a clean
   set of files, then repeated the change of database passwords, salt etc. This 
   time round I also changed the cpanel password.
 * When I looked through Ninjafirewall logs, I didn’t notice any UPLOAD event. However
   when I checked the website access logs, I noticed POST requests to the login 
   page and theme-editor.php file.
 * I’m still not sure how the password got changed and the malicious files got into
   the server. My guess is maybe they got access to the FTP using the cPanel password,
   or plugin issue, or somehow managed to bypass the firewall (unlikely I feel).
 * For now I’ve ensured all plugins and core is updated. I’ve set DISABLE_FILE_MODS
   to true in wp-config. And in Ninjafirewall, I’ve also enabled the option to block
   POST requests in theme folder. Let’s see how it goes.
 * Aside to this, we have another site hacked on the same VPS server but in another
   cPanel. Not sure if this is linked.

 * That doesn’t look good. They were able to log in.
 * How many admin users do you have? Did you change all their passwords since last
   hack (you only mentioned DB password and salt keys)? Is their contact email address
   correct? Check also email forwarding in cPanel, often hackers add their email
   address to that section to receive password reset notification.
 * How about the contact email from the “Settings > General” page?
 * Make sure to run the firewall in “Full WAF” mode and enable both “File Check”
   and “File Guard” in the monitoring section.

 * Thanks for the quick responses. We have 3 admin users (2 used by developers, 
   1 used by client) and 1 editor account. I didn’t change all their passwords for
   the previous hack. But the 2nd round I changed for all the accounts. The contact
   email address for all the admin accounts are correct. The contact email in Settings
   > General page is correct too.
 * I have turned on Full WAF and also enabled File Check + File Guard. I’ve also
   enabled all the options in “Block direct access to any PHP file located in one
   of these directories”.
 * We will be migrating the site to a new server tonight after doing offline scans
   and checks.
 * My main concern is still regarding the allowing of users to upload files from
   the contact form. Could that be the entry point?
 * Some other info:
 * Wordpress is latest 5.5 now. Before the hack it was 5.4.2.
 * Here are the plugins used:
 * Advanced Custom Fields 5.9.0
    DynamicConditions 1.4.6 Ele Custom Skin 3.0.0 Elementor
   2.9.14 Elementor Pro 2.10.3 Google Tag Manager for WordPress 1.11.4 Make Column
   Clickable Elementor 1.3.1 NinjaFirewall (WP Edition) 4.2.4 NinjaScanner 2.0.7
   Radio Buttons for Taxonomies 2.0.5 Yoast Duplicate Post 3.2.5 Yoast SEO 14.8.1
 * I’ve checked these plugins inside the [https://wpvulndb.com/](https://wpvulndb.com/)
   and versions seem to look ok.

 * Make sure your contact form uses a whitelist of allowed files, user shouldn’t
   be allowed to upload PHP scripts, system files etc.
    In Full WAF mode, if someone
   uploaded a PHP scripts and accessed it, it would trigger an alert from the “File
   Guard” feature.

   remove the previous post if necessary._
 * I got a few triggers from NinjaFirewall’s File Guard detection from an IP address
   in Ukraine.
 * Nothing else happened. No database changes detected. New server is using nginx
   and we have implemented some blacklist and whitelist rules. Here are some info–

 * It is an attempt to preview a post created by Elementor, but it should fail if
   the user isn’t allow to edit it:

 * Thank you [@nintechnet](https://wordpress.org/support/users/nintechnet/)
 * We are still monitoring the site on our new server. It seems that our previous
   server had all the WordPress sites hacked. We see malicious php.ini files which
   enabled shell_exec and turned off disable_functions.
 * I guess the old server was not hardened by the previous sysadmin as we can see
   cPanel security advisor reported quite a few serious issues. When checked thoroughly,
   the remote mysql was actually enabled. We have disabled it now. It’s going to
   be a long week ahead to try and restore this.
 * We plan to install NinjaFirewall for all the sites using wp-cli. But the default
   install requires us to manually activate Full WAF mode. Is there a way to do 
   this via the wp-cli? If we could enable the full WAF mode and apply an exported
   configuration with wp-cli would be good.

 * It’s not possible yet because WP CLI uses the PHP command line interpreter and
   it doesn’t populate some `$_SERVER` variables, unlike the PHP web interpreter.
   
   We’re working on it but I’m not sure if that will be possible or not.

 * Thank you. I guess we will install and setup invidually per site. It seems to
   be doing OK for now so we will continue monitoring and mark this as resolved.
