## Description

DeJack (combined from the prefix “De” and "hijacking” to infer the meaning of undoing a hijack) does DNS security checks and gathers security information about it with one click of a button. 
<ul><li>If a website is flagged as suspicious, it's likely vulnerable to one or more of the three types of DNS hijacking: man-in-the-middle, cache poisoning, and DNS redirection cyberattacks. </li><li>You will find it provides recommended tools and steps to take to become safer online as well. </li></ul>
<strong>The goal in this endeavor is to help users gain more control over their online safety through an easier path and raise awareness of a common cyberattack known as DNS hijacking. </strong>
