Finding WordPress Hacks

You may have heard about a hacker exploiting a particular vulnerability in your WordPress site and causing damage. But, how do you know if you’re vulnerable to attack?
The first step would be to check your site’s version of WordPress. If it’s not up-to-date, update it immediately.
If that doesn’t work, you can use the WP Security Scan plugin to scan your site for any potential vulnerabilities. As long as you have the plugin installed, it will check all the core files of your site for known vulnerabilities and tell you if there are any holes that need patching.
If this is not an option, then we recommend using a backup plugin like BackWPUp or UpdraftPlus to make sure that your website is secure when things go wrong

If you’re using Gallery and are affected by this vulnerability, you should immediately update to version 1.8.4.7 or later of the plugin. You will also need to change your site’s Gallery theme to one that is not affected by this vulnerability, such as the default Twenty Twelve theme.

Why Is This Issue Important?

This issue is important because malicious users can exploit the vulnerability to inject malicious code into a site’s gallery. This may then be used to steal sensitive data or perform other nefarious actions.
Why should I worry?
If you’re using this plugin, please update as soon as possible.
