Capture the Flag 2022

This friendly competition features challenges that showcase the work and interests of the Australian Signals Directorate (ASD). 

Topics include cryptology, reverse engineering, adversarial machine learning, languages, computational linguistics, open-source intelligence and more! 
There are great prizes, plus the opportunity to meet challenge writers and learn how you could get paid to solve challenges like these in a career at ASD! 
New to CTFs? That's ok! No previous cybersecurity skills are required, you can pick them up as you solve the challenges.  
The maximum team size is 6 members. If you don't have a team, join our Discord server and we can help you find one. Joining our server will allow you to connect with other players. 
This competition is a great way to learn about cyber defence and gain insights into new tools and techniques.
