Capture the flag with Co-Lab

Co-Lab capture the flag

The Co-Lab is running a 'Capture the Flag' event for Australian citizens who are students or staff at ANU.

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 include software reverse engineering, digital forensics, computational linguistics, and mathematical cryptography.

It’s also a lot of fun!



Throughout the day, discussion will be conducted online via the ANU Co-Lab Team on the Microsoft Teams Platform (open to registered participants).

There will be two live sessions for all participants: 

  • 9-9.15am Welcome and CTF overview
  • 5-6pm Wrap-up session including Q&A with challenge designers



  • A computing device on which you can install command-line software. 
  • Your favourite programming environment(s) - Python is very common in CTFs
  • Freely downloadable security tools like Ghidra and Wireshark are often useful in CTF challenges. If you’re really serious, install a Linux distribution like Kali (or virtual machine) for access to common security tools.
  • A forum to meet and discuss with your teammates e.g. your ANU account on Microsoft Teams.


Create a team of 3-6 or we’ll find you a team! Register your interest today!

Please note registration is open to Australian citizens who are students or staff at ANU. Registration closes at 5pm on Friday 4 September.
