Impact of Malware

Once malware infects your WordPress website or system, it can trigger a variety of serious issues, including:

Data Compromise: Malware can steal or corrupt sensitive data, such as personal information, financial records, and intellectual property. This can lead to identity theft, financial loss, and severe damage to your reputation.

Unauthorized Access: Many types of malware create backdoors, giving attackers unauthorized entry to your systems. This opens the door for further exploitation, including the installation of additional hidden malware or using your system to launch attacks on others.

Performance Decline: Malware often consumes excessive system resources, causing your computer or network to slow down. This results in decreased productivity and frustration as your system becomes sluggish and unresponsive.

System Failure: In extreme cases, malware can cause complete system failure, making your computer or network unusable. This can lead to prolonged downtime, significant data loss, and costly repairs or replacements.

To start with Malware removal on your WP site turn on Maintenance Mode on your site

Audit the admin list Many of these admin users will use a random or bogus email address meaning the password reset will completely revoke the user access, meaning they cannot reset the password due to the email address used but this shouldn’t be assumed.

wp user list --role=administrator Remove any that you don’t recognize with wp user delete userID

Searching the database for scripts

wp db search '(<script|eval\(|atob|fromCharCode)' --regex

Verifying checksums wp core verify-checksums Small and non-malicious changes to your WordPress files could cause the checksum verification to fail — this includes things as simple as removing the readme.txt file. If it fails, the tool will give you a list of files to check.

wp plugin verify-checksums --all We can only verify plugin checksums for plugins available from WordPress.org, while a few premium plugin devs do offer checksum tools for WP CLI, they aren’t available out of the box.

Reinstall all plugins and Themes available from WordPress.org

wp plugin install $(wp plugin list --field=name) --force --skip-plugins --skip-themes

wp theme install $(wp theme list --field=name) --force --skip-plugins --skip-themeswp plugin install $(wp plugin list --field=name) --force --skip-plugins --skip-themes

Forcing the new WP core Rename the wp-admin and wp-includes directories. This is to ensure that nothing is left behind in the WP core. Once renamed, run the command:

wp core download --version=6.2 --skip-content --force After you make sure that the WP core is not broken, you can quarantine the wp-admin and wp-includes directories.
