Get ready to hack! The CTF is back at WHY2025!

Brought to you by the same team behind the legendary CTFs at OHM2013, SHA2017, and MCH2022. After a well-earned break, we’re back—bigger, better, and more challenging than ever! Just like in 2022, we will have both online and on-site challenges, making the CTF accessible to everyone. Whether you’re a seasoned hacker or a total beginner, there’s a challenge waiting for you.

Before the main event, we’re giving you a small taste of what’s to come! From March 21-23, 2025, we’ll host an online teaser CTF with a handful of challenges to get you in the mood.
