In the ever-evolving digital landscape, the security of your WordPress site cannot be taken for granted. Cyber threats are becoming more sophisticated, making it crucial for businesses to fortify their online presence against unauthorized access. At Webonology, we’re deeply committed to not just securing our clients’ websites but also empowering the broader online community with effective tools and knowledge to protect their digital assets.
Identifying the Threat
Through diligent security practices and continuous monitoring, we’ve identified a recurring issue that poses a significant risk to WordPress sites: the creation of unauthorized administrator accounts, especially those following the “wp_update_XXXXX” naming pattern. This subtle yet dangerous vulnerability can serve as a gateway for malicious activities, compromising the integrity and safety of your website.
Our Proactive Solution
Understanding the critical nature of this threat, Webonology has taken substantial measures to address it head-on. We’ve developed a WordPress code snippet designed to automatically detect and delete user accounts with usernames starting with “wp_update-“. Moreover, this solution sends an email notification to the site administrator, informing them of the deletion, thus ensuring immediate remediation of potential security threats without the need for constant manual monitoring.
Here’s the code we’re sharing with the community:
function delete_specific_users_and_content_and_notify() {
if (is_admin()) {
$users = get_users(array('search' => 'wp_update-*'));
foreach ($users as $user) {
// Check if the username indeed starts with "wp_update-"
if (substr($user->user_login, 0, 10) === "wp_update-") {
require_once(ABSPATH.'wp-admin/includes/user.php');
// Get all posts by the user
$user_posts = get_posts(array('author' => $user->ID, 'post_type' => 'any', 'numberposts' => -1));
// Delete each post
foreach ($user_posts as $user_post) {
wp_delete_post($user_post->ID, true); // Set to true to bypass trash
}
// Finally, delete the user
wp_delete_user($user->ID, 1); // Reassign posts to user ID 1 (usually the admin)
// Prepare and send the notification email
$to = 'your@emailaddress'; // Change this to your email address
$subject = '[WEB SECURITY] ' . get_bloginfo('url');
$message = 'Site Name: ' . get_bloginfo('name') . "\r\n" .
'Site URL: ' . get_bloginfo('url') . "\r\n" .
'Deleted Username: ' . $user->user_login;
wp_mail($to, $subject, $message);
}
}
}
}
// Hook this function to a proper action that suits your use case.
add_action('admin_init', 'delete_specific_users_and_content_and_notify');
This code exemplifies our commitment to creating a secure online environment for businesses. By automating the detection and removal of suspicious user accounts, we’re not just protecting individual sites but also contributing to the overall safety of the WordPress ecosystem.
