Congrats to the next generation of CTF players @radboud_rip for getting the second place! Well done, impressive skills. Next time you will probably beat us ;-)

The final #HITB2023AMS CTF scoreboard! We are happy to have been able to compete in this CTF for the past 10 years. We are sad to see it go, but proud we were able to get the first place this last time.

The #MCH2022CTF badge challenge was mentioned on @hackaday A correction though, the challenge was not a CTF itself, the challenge was part of the official #MCH2022 CTF: ctf.mch2022.org

Thanks for this *awesome* CTF! ❤️ We set ourselves the goal to reach Top 10 - which we did by taking the 8. place! We are especially proud to be one of only two teams that solved the "Hack Me If You Can" challenge, and to be the first team to solve "Weird Signal" 😊 @MCH2022Camp

The final top 15 of #MCH2022CTF, congrats to @0rganizers, ChaosWest and duks! Awesome scores, very well played, and it was really nice to see you all compete and to meet the teams onsite.

Back from a very successful #MCH2022 where I hosted the #MCH2022CTF together with @asby and onsite help from @the_ius Thank you all for playing, we will be back in 2025. Follow @MCH2022CTF for updates


We would like to thank all the volunteers, and especially all the 'orga' who made #MCH2022 possible. Organizing a camp like this takes an insane amount of work. Thank you so much! We really loved the camp and being able to be a part of this. Thanks!


The final top 10 of #MCH2022 Secret Tokens challenge, congrats to you all! The amount of tokens found is really impressive. This was the first time we did the Secret Tokens challenge and we really liked how enthusiastic you all were about it. We will definitely return with it!
