Steps to removing malware, spam, and other hacks from WordPress .Sucuri has devoted years to helping WordPress administrators identify and fix hacked websites. To continue with this process, Sucuri have put together this guide to help website owners walk through the process of identifying and cleaning a WordPress hack. This is not meant to be an all-encompassing guide, but if followed, should help address 70% of the infections we see.
You can use tools that scan your site remotely to find malicious payloads and malware locations. Sucuri has a free WordPress plugin that you can find in the WordPress official repository.
To scan WordPress for hacks:
If the remote scanner isn’t able to find a payload, continue with other tests in this section. You can also manually review the iFrames / Links / Scripts tab of the Malware Scan to look for unfamiliar or suspicious elements.
If you have multiple websites on the same server we recommend scanning them all (you can also use SiteCheck to do this). Cross-site contamination is one of the leading causes of reinfections. We encourage every website owner to isolate their hosting and web accounts.
Most core WordPress files should never be modified. You need to check for integrity issues in the wp-admin, wp-includes, and root folders.
The quickest way to confirm the integrity of your WordPress core files is by using the diff command in terminal. If you are not comfortable using the command line, you can manually check your files via SFTP.
If nothing has been modified, your core files are clean.
If your WordPress site has been blacklisted by Google or other website security authorities, you can use their diagnostic tools to check the security status of your website.
To check your Google Transparency Report:
If you have added your site to any free webmaster tools, you can check their security ratings and reports for your website. If you do not already have accounts for these free monitoring tools, we highly recommend that you sign up as they are free to use:
Now that you have information about malware locations, you can remove malware from WordPress and restore your website to a clean state.
The best way to identify hacked files is by comparing the current state of the site with an old and clean backup. If a backup is available, you can use that to compare the two versions and identify what has been modified.
If the infection is in your core files or plugins, you can fix it manually, just don’t overwrite your wp-config.php file or wp-content folder.
Custom files can be replaced with fresh copies, or a recent backup (if it’s not infected). Here are some additional tips & tricks that you can use with WordPress.
You can use any malicious payloads or suspicious files found in the first step to remove the hack.
