Game of Thrones Hacking CTF

This is a challenge-game to measure your hacking skills. Set in Game of Thrones fantasy world.


Goal:

Get the 7 kingdom flags and the 4 extra content flags (3 secret flags + final battle flag). There are 11 in total.

Rules/guidelines to play:

  • Start your conquer of the seven kingdoms
  • You'll need hacking skills, no Game of Thrones knowledge is required. But if you play, it may contains spoilers of the TV series
  • Difficulty of the CTF: Medium-High
  • Don't forget to take your map (try to find it). It will guide you about the natural flag order to follow over the kingdoms
  • Listen CAREFULLY to the hints. If you are stuck, read the hints again!
  • Powerful fail2ban spells were cast everywhere. Bruteforce is not an option for this CTF (2 minutes ban penalty)
  • The flags are 32 chars strings. Keep'em all! you'll need them

Requirements/starting guide:

  • Import the Linux based CTF challenge virtual machine (OVA file)
  • OVA file is compatible with Oracle Virtualbox and Vmware
  • The challenge vm needs 1 cpu and 1512mb RAM to work properly
  • The challenge vm has its network configured by default as bridge. It will take an IP from the DHCP of your network

Downloading challenge CTF vm:

Troubleshooting

  • Vmware:
  • If you get a warning/error importing machine, press "Retry" and it will be imported flawlessly
  • Oracle Virtualbox
  • It's recommended to use "Import Appliance" menu option instead of double click on OVA file
  • If you get an error regarding network, just select your network interface

Good luck, the old gods and the new will protect you!

ARM Lab Environment

Let’s say you got curious about ARM assembly or exploitation and want to write your first assembly scripts or solve some ARM challenges. For that you either need an Arm device (e.g. Raspberry Pi), or you set up your lab environment in a VM for quick access.

This page contains 3 levels of lab setup laziness.

  • Manual Setup – Level 0
  • Ain’t nobody got time for that – Level 1
  • Ain’t nobody got time for that – Level 2

Manual Setup – Level 0

If you have the time and nerves to set up the lab environment yourself, I’d recommend doing it. You might get stuck, but you might also learn a lot in the process. Knowing how to emulate things with QEMU also enables you to choose what ARM version you want to emulate in case you want to practice on a specific processor.

How to emulate Raspbian with QEMU.


Ain’t nobody got time for that – Level 1

Welcome on laziness level 1. I see you don’t have time to struggle through various linux and QEMU errors, or maybe you’ve tried setting it up yourself but some random error occurred and after spending hours trying to fix it, you’ve had enough.

Don’t worry, here’s a solution: Hugsy (aka creator of GEF) released ready-to-play Qemu images for architectures like ARM, MIPS, PowerPC, SPARC, AARCH64, etc. to play with. All you need is Qemu. Then download the link to your image, and unzip the archive.

Become a ninja on non-x86 architectures


Ain’t nobody got time for that – Level 2

Let me guess, you don’t want to bother with any of this and just want a ready-made Ubuntu VM with all QEMU stuff setup and ready-to-play. Very well. The first Azeria-Labs VM is ready. It’s a naked Ubuntu VM containing an emulated ARMv6l.

This VM is also for those of you who tried emulating ARM with QEMU but got stuck for inexplicable linux reasons. I understand the struggle, trust me.

  • Ubuntu 16.04.3 LTS 64-bit (kernel 4.10.0-38-generic) with Gnome 3
  • HDD: ~26GB (ext4) + ~4GB Swap
  • RAM (configured): 4GB

I’ve included a Lab VM Starter Guide and set it as the background image of the VM. It explains how to start up QEMU, how to write your first assembly program, how to assemble and disassemble, and some debugging basics. Enjoy!
