Here are some of the Forum/Website to visit on dark web related to cybersecurity and hacking. Before visiting this website please follow the steps to be safe on the dark web/ Deepweb. Security Steps to be taken before opening the links: First of All, To browse these dark web forums, first close all active programs and applications in your computer then start Your NordVPN or any Paid and HQ VPN that have TOR service and select Onion Over VPN Server.  Now start Tor Browser and disable Javascript. In this way, you have created a completely secure and untraceable environment for you. If you think Tor Browser gives you full anonymity then you are wrong.  Only premium VPN services can provide you fully secure and untraceable environment. I have tried my hands on many premium VPN services, and I found NordVPN beats its competitor in all features.
