Capture the Flag: 15 & 16 April 2019

ANU has invited Australian Signals Directorate to run a 'Capture the Flag' event on campus.

Capture the Flag (CTF) is a friendly competition consisting of assorted cyber security and cryptography problems and puzzles. Participants work in teams to solve these problems; successfully solving a problem yields a flag which can be submitted to a server which gives your team the points for that problem.  More broadly, a CTF is a hands-on learning tool for anyone interested in developing their skills in cyber defence and attack methodologies. Some of the problem categories for this particular CTF are software reverse engineering, web exploitation and mathematical cryptography. It’s also a lot of fun!

Throughout the event, the makers of the CTF will be available to talk about and lend a hand with some of the challenges they created. There will also be a pizza party to bring all the teams together to talk about their progress against the challenges at 1800 on Monday April 15th.

Dinner will be at 1800 on Monday April 15th.


  • Bring a computing device (phones and tablets won’t quite cut it) for the challenges.
  • Install your favourite programming environment (python is very common in CTFs)
  • Freely downloadable tools like Wireshark will often see use in CTF challenges.
  • If you’re really serious, install a Linux distribution like Kali (or virtual machine) for access to common security tools.
  • Access to scrap paper or whiteboard.

Create a team of 4 or 5 and register your interest today!
