Bypass Firewalls by Tunneling Data and Commands over DNS new

The video tutorial explains how attackers can exploit DNS port vulnerabilities to establish a command and control channel. It provides a step-by-step guide to setting up a DNSCat2 server on a Kali machine and installing the client on Windows. The tutorial demonstrates how to establish a command and control channel over DNS and monitor the traffic using Wireshark. It concludes with security measures to protect against such attacks.
