Pentest Limited's SecuriCTF Write up

From time to time, I have time to look at and try some CTF (Capture the Flag) VMs to try to get root on. These are purpose built VMs to challenge people to break in. For the Securi-Tay 2017 conference, Pentest Limited released a CTF VM, and even though the solution was posted I decided to give it a go to see how I faired. The VM was aimed at the novice level, so I was in with a chance.



Once the VM was booted in virtualbox, I was presented with the IP address of the VM from inside the console screen. In this case my target was 192.168.56.101. My attacking machine (Kali Linux) was sitting on 192.168.56.1. As this is my virtualbox network, I knew that there shouldn't be anything else on the LAN, so I did a ping sweep to confirm, using nmap. The nmap command is




nmap -sP 192.168.56.1/24




 


Keybase on Kali Linux

Kaybase.io is a great platform for sharing PGP keys and verifying your identity online. The Linux tools the platform works with, however, don't run with Kali Linux out of the box. The reason is simple: Root (UID: 0) isn't supported. So how do you over come this limitation? In my case, my laptop is only used by me, and no one else.



NB, you should be using a dedicated machine to store your private keys. If not, you do run the risk of administrators being able to try to break in to keys / steal your keystrokes / etc.
