Install WPScan on Ubuntu 16.04 for WordPress Vulnerability Scanning

WPScan is a WordPress vulnerability scanner written in Ruby. It is sponsored by Sucuri and hosted on github. Using its security vulnerability database for WordPress core, plugins and themes it will provide a report on your site’s known security problems which can be exploited by hackers.

If you ever wondered how a hacker knows your WordPress username and is trying to guess the password by brute force, WPScan is probably the explanation. I will be explaining how this works and how to prevent it in upcoming posts.

ruby wpscan.rb --url https://wp-bullet.com

You will see quite a lot of information. I will be posting a series of tutorials for nginx, Apache and Varnish that show how to block a lot of the information that WPScan gathers by making some configuration changes. Stay tuned!
