- If you want to join, it would be useful if you know some of these:
- Coding
- Git
- Docker
- Linux
- Web DevTools
- C, assembly or other low-level-programming
- We are also there to have fun, not to teach you – that’s on you and your motivation. We can give you some pointers and resources for self-learning though.
- Become a part of the Austrian CTF-Community and join the ACSC qualifiers in 2027 again. You can find further info on acsc.land
