Many people believe that browser security is difficult. I created this guide as an overview of Firejail sandboxing technology. The goal is to show you that security can be simple and fun.

The guide is structured as a hacking session. The victim is running a sandboxed browser. An imaginary zero-day exploit gives the attacker control of the sandbox in the form of a remote shell. Let's see what damage we can do. And maybe, reconfigure the sandbox so the victim can survive the aftermath of such an attack.

Sandbox command: firejail --name=browser --dns=9.9.9.9 --net=enp3s0 --netfilter=/etc/firejail/nolocal.net firefox
