@file_put_contents($l1, 'css');
Malicious users with admin privileges: wpsupp-user, admim, [email protected], [email protected]
Cleanup steps
- Clean and update the core WordPress files, including wp-config.php.
- Review the plugins, apply the available updates, and delete the malicious folders.
- Check the functions.php file inside the theme folder and delete the malicious code. Look for the following strings: “function bestrock_render_js”, “base64_decode”, and “@file_put_contents”.
