Walkthrough

You will be sent a credential bundle from the Taskmaster. Please untar the files:

cd ~/Downloads
tar xf <id>.tar.gz
ls

You should see the following files:

cp_simulator_config  cp_simulator_rsa

We're now ready to connect onto the cluster, run the following ssh command:

ssh -F ./cp_simulator_config -oIdentitiesOnly=yes bastion

This will connect us into our Attack cluster. Please type yes when asked if you want to continue to connect.

Attack

When you are connected onto the cluster, you're ready to go! Remember:

  • The scenario instructions have useful info, and tips about where to start the hunt
  • Flags are in the format flag_ctf{636f6e74726f6c706c616e65}
  • Pay attention to your starting point

TIP: keep a track of what you're doing, copy the tips from the start and keep notes to track your own progress as you work through the attack.
