100 Days of Hacking — Day 11

What’s up fellow hackers! it’s day 11 of the 100daysofhacking challenge.

Objectives of day 11 :

  1. What’s the big deal about ssh key cracking and how to do it with john the ripper
  2. Try hacking a tryhackme room (okay poor technical joke there)

Reports of day 11 :

https://linuxconfig.org/ssh-password-testing-with-hydra-on-kali-linux

https://bughacking.com/how-to-crack-ssh-private-key-with-john-the-ripper/

These were the resources I referred to and provided a great deal of my understanding of SSH keys. I am learning these stuff just now :”) whereas I’ve been using these id_rsa keys for a long time (2 months or so).

Now I tried this room https://tryhackme.com/room/gamingserver

It has ssh2john in it’s label so I chose this one.

Eureka moment : My script for CTF automation is working honestly it was just a few minutes and I grabbed the user.txt

The privilege escalation part was a bit tough and I couldn’t do it. It was a new topic and I thought I should spend separate time on that.

It was about lxd group containers which is used to mount root folder on host machine.

Back to this bible where lxd/lxc privilege escalation is explained well. Anyways I watched this and the concept became clearer https://www.youtube.com/watch?v=7x4gwV632o0
