Netrunner is the second biggest challenge of the Santhacklaus 2018 CTF. The challenge is not really hard, but could be particulary annoying if you don’t know what to do. You need to have some skills in pentest web and medium skills in Linux system.
The challenge is divided in 3 steps. Each step has its own validation password (flag). So let’s begin with the first step !
1st step - You have a mission !
