WordPress, in particular, powers over 40% of the websites on the internet. This makes it a primary target for hackers. However, it is open source, and the community behind WordPress will always track and issue fixes as soon as possible for all known vulnerabilities. Furthermore, there are themes/plugins by millions of developers worldwide; these themes/plugins can be built to standard or not and may require updates as well, etc.

If you host any WordPress site here or anywhere, it is important to administer it consistently. Ensure you update it always; review your setup; its basic site administration techniques are required. We collected a few guides from Google and advised you to learn more.

Here are a few things to note:

1. Plugins: Third-party plugins account for most WordPress security breaches. Since plugins are created by third parties and have access to the backend of your website, they're a common channel for hackers to disrupt your site’s functionality.

2.Outdated WordPress versions: WordPress sometimes releases new versions of its software to patch security vulnerabilities. When fixes come out, the vulnerabilities become public knowledge, and hackers often target problems with old versions of WordPress.

3. The login page: The backend login page for any WordPress website, by default, is the site’s main URL with “/wp-admin” or “/wp-login.php” added to the end. Attackers can easily find this page and attempt a brute-force entry. This is important to use highly secure usernames and passwords.

4. Themes: Yes, even your WordPress theme can open your site to cyberattacks. Outdated themes may be incompatible with the most recent version of WordPress, allowing easy access to your source files. Also, many third-party themes do not follow WordPress’ standards for code, causing compatibility issues and similar vulnerabilities. Avoiding themes from random sources, especially premium themes that you find distributed for free, is important. They are often infiltrated with malicious code you may not see. 

Managing your WordPress site is a continuous exercise that you should do regularly.

** TIP: do not set up WordPress for temporary things; keep it publicly accessible without removing it after you finish your testings. Any setup you do that is ignored will eventually be outdated, and hackers can hijack it through known or unknown vulnerabilities.
