Another way hackers mine for admin email addresses is by exploiting author archives. WordPress generates an author archive page for every user, and by adding /?author=1, /?author=2, etc. to a WordPress URL, hackers can find usernames and correlate them with admin accounts.

Hackers can also use enumeration plugins to list out WordPress users and reveal user IDs and email addresses associated with those accounts.

In some cases, hackers can even use default WordPress features like lost-password retrieval and user registration to mine admin email addresses. These features can inadvertently reveal user emails, making it easier for hackers to target your admin accounts.

Hackers may also use site metadata to reveal usernames and email addresses. This can be done by inspecting metadata, such as author information or site description, to identify potential admin details.

Here are some common ways hackers mine for admin email addresses:

  • Exploiting author archives
  • Using enumeration plugins
  • Exploiting default WordPress features
  • Using site metadata
  • Exploiting XML-RPC
  • Using the REST API

It's essential to understand these methods to protect your WordPress site and prevent hackers from mining your admin email address.

Mining the REST API is a tactic hackers use to extract sensitive information from your website. This can include usernames and email addresses, which they can then use for phishing attempts or password resets.

Hackers often scan for known vulnerabilities in plugins and themes to extract such information. They can use this information to gain unauthorized access to your website.

To understand how hackers exploit the REST API, consider this example: by sending a request to the API endpoint /wp-json/wp/v2/users/, hackers can retrieve a JSON response containing usernames and, in some cases, email addresses. This is a publicly available endpoint that can be accessed with minimal technical expertise.

Here are some ways hackers can use the REST API to mine emails:

  • They can send a request to the API endpoint /wp-json/wp/v2/users/ to retrieve a list of usernames and email addresses.
  • They can use this information to target your admin accounts with phishing attempts or password resets.

Exploiting Password Reset Forms

Hackers often test various email addresses using the password reset feature. If the form returns a message that says, “An email has been sent to the account,” the hacker knows the email is valid.

This technique is a clever way for hackers to gather valid email addresses. They can now focus on phishing or brute-force methods to gain access.

Here's how hackers exploit password reset forms:

  • They send multiple requests to the password reset form with different email addresses.
  • They check the response to see if an email has been sent to the account.
  • If the response is positive, they know the email address is valid.

By using this method, hackers can collect a list of valid email addresses, making it easier to target your WordPress site with phishing attempts or brute-force attacks.

How Exploit Gravatar

Hackers can exploit Gravatar by taking the MD5 hash of an email address and reversing it using various tools to find the original email address. This allows them to target admin emails for attacks.

Gravatar uses an MD5 hash of the email to generate the avatar, which is not the same as exposing the raw email address. However, hackers can still find the original email address.

Hackers can use Gravatar to mine admin email addresses, especially if you have a WordPress site with comments enabled. Every user who leaves a comment links their email address to their Gravatar.

Using a Gravatar privacy plugin like Simple Local Avatars can help prevent email mining through comments and Gravatars. This plugin allows you to host avatars locally without revealing email addresses.
