Open up and excerpt the contents of the .zip on your estimator. The WordPress cadre files will be extracted in a wordpress folder.

Double click the folder to view the files within of it. You'll encounter all of the WordPress core files for v5.one.i inside of the binder.

Afterward doing so, you would delete the infected wp-config.php and rename the wp-config-sample.php to wp-config.php.

3. Check Uploads Folder

The WordPress Uploads folder is also a common place you lot may run into malicious .php files. To cheque the Uploads binder you'll go to your public_html or document root, click into the wp-content folder, and click into the uploads folder.

Inside of the Uploads binder yous'll meet folders that incorporate the names of each year yous've uploaded files via the WordPress Media functionality in the admin dashboard.

Inside each folder for each yr contains folders for each month. Yous will need to manually check every binder for .php files.

In this case, we're going to click into the 2019 > 04 uploads binder. We notice a .php file 35p508rb.php sitting in that folder.

Correct click the .php file to edit the file and y'all'll run across that it's indeed a malicious file. It might look something like the image below:

Later on showing hidden files, you may encounter the .well-known folder like the image below. If in that location is no .well-known folder, you tin move onto the adjacent stride.

An alphabetize.php typically isn't placed into the .well-known binder and that's why this looks suspicious at starting time glance.

After clicking Edit and viewing the contents of the alphabetize.php, we tin see that it's some other malicious file. Select the file and delete it from the .well-known binder.

You may meet 2 foldres in the .well-known folder. 2 of the most common are pki-validation and peak-claiming. You will need to bank check both of these folders for suspicious files also. If these folders comprise .txt files, those are most likely the verification files used to confirm buying of your domain when an SSL Certificate was issued.

If you think you've cleaned the folders from malicious files you tin proceed to Step 6.

In this case, information technology looks like we missed a .php file sitting in the public_html.

We deleted this file and checked everything once again for any files we may have missed.

6. Re-Install Fresh Copies of Your Plugins

At present that y'all've cleaned your WordPress core files and folders y'all can focus on re-installing your WordPress plugins. Plugins by tertiary-political party developers (even more popular plugins) are normally the culprit to your WordPress site beingness hacked or compromised.

Some premium/paid plugins may never prove updates available/out of date warnings in the WordPress admin dashboard or Plugins page. You demand to check the 3rd-party marketplace or programmer'due south website you purchased it from to make certain you accept an upwards to engagement version of that plugin.

Before proceeding with the re-installation of plugins you'll desire to get through and perform the post-obit:

• Delete deactivated plugins
• Remove plugins that oasis't been updated in 6+ months
• Remove plugins not required for functionality (e.g., remove a Google Analytics plugin and manually place the Google Analytics code into your agile theme's header.php)

How that yous've removed inactive and outdated plugins y'all can focus on re-installing fresh copies of the plugins that remain. If your site is still inaccessible (since it's hacked or compromised), you'll need to log back into cPanel and access the File Manager.

Navigate into the public_html or certificate root of your addon domain/subdomain and go to wp-content > plugins to view the list of plugins currently installed. In this example, nosotros have iv plugins installed.

Repeat this step for each plugin you lot have installed on your WordPress site.

7. Re-Install a Fresh Re-create of Your Active Theme

Similar to the previous footstep (Step six) for plugins, you will need to download a fresh copy of your active theme, delete the old copy of your theme, and re-install the new theme files. If you purchased your theme from a third-party market or developer you volition need to make sure to download a fresh copy of the theme files from that source since it won't be in the free WordPress.org market.

In this example, you can see that we have 4 themes installed. Our current active theme is a complimentary theme called storefront. We'll need to download a fresh copy of that theme'southward files.

Go to https://wordpress.org/themes/ and search for storefront.

Next, upload the theme .cypher you downloaded from the WordPress.org market. Do this inside the File Manager and make sure you're in the /wp-content/themes/ folder.

After the theme .nil has been uploaded you will run into the .zip file in the themes binder. Delete the existing theme folder and Excerpt the files for the theme from the new .zip you uploaded.

Often times exploits or vulnerabilities in WordPress, themes, or plugins will allow the "hacker" or person attacking your site to create a user in the admin dashboard. Bold you've follow the previous steps in a higher place, y'all should exist able to access the WordPress admin dashboard if you weren't able to access it before.

Check to make sure there aren't any users accounts yous don't recognize. If at that place's whatever users you don't recognize or you're unsure about delete those user accounts.

We as well recommend updating the passwords to any user accounts that weren't deleted.

ix. Disable File Editing

A expert practice to improve the security of your site is to disable the file editor for themes and plugins in the WordPress admin dashboard. To do this will require you to place a snippet of code in your wp-config.php.

Copy the code below:

## Disable Editing in Dashboard define('DISALLOW_FILE_EDIT', truthful);

Access the File Managing director in cPanel and navigate back to your public_html or document root. Find the wp-config.php and right click to Edit the file.

Curlicue downward and place the snippet of lawmaking under the line of code displaying define('WP_DEBUG', false);. Click the Salve push button in the upper correct corner.

If an aggressor gains access to your WordPress dashboard this will forbid that attacker from making file edits to the theme files and plugin files.

Security is not an absolute, it's a continuous procedure and should exist managed as such. Security is about risk reduction, non gamble elimination, and risk volition never exist cypher. It's nigh employing the appropriate security controls that best assistance address the risks and threats as they pertain to your website. – WordPress.org

Keep in mind that performing a site cleanup doesn't guarantee that your WordPress site(s) won't be compromised or infected once more. If yous continue to utilize third-party plugins and themes you may exist susceptible to vulnerabilities if the third-party developer of those plugins and themes oasis't kept those plugins and themes updated. In that case, we highly recommend you lot observe culling plugins for those or delete them entirely.

Lastly, yous should delete any plugins that aren't being used and are inactive. Inactive plugins and having a lot of plugins installed can create a potential adventure and even cause bloat to your WordPress site leading to operation bug.
