22 Hacking Sites, CTFs and Wargames To Practice Your Hacking Skills
InfoSec skills are in such high demand right now. As the world continues to turn everything into an app and connect even the most basic devices to the internet, the demand is only going to grow, so it’s no surprise everyone wants to learn hacking these days.


However, almost every day I come across a forum post where someone is asking where they should begin to learn hacking or how to practice hacking. I’ve compiled this list of some of the best hacking sites to hopefully be a valuable resource for those wondering how they can build and practice their hacking skill set. I hope you find this list helpful, and if you know of any other quality hacking sites, please let me know in the comments, so I can add them to the list.
