Back to regular schedule of CTFs (almost) every weekend
Greetings fleshlings,
Summer is officially over, we have CTFs and the semester ramping up again, so we might also have more students joining us. I added the events for this month into our calendar and here's the breakdown (we always meetup at SBA Research, Floragasse 7, 5th Floor, unless mentioned otherwise):
2026-10-10: FortID CTF. We have no idea what to expect from this one, but the rating on CTFtime seems decent. We are meeting on Saturday from 10:00 onwards.
2026-10-17: Next try for Securinets CTF. In case it gets moved again, there should still be other CTFs to play. This one starts at 11:00 on Saturday, I will most likely be at SBA from 10:00 onwards already.
2026-10-24: HITCON CTF, expect hard challenges. We meet starting from 10:00 on Saturday. Unfortunately there's also Hack.lu CTF running in parallel, maybe we are lucky and Hack.lu CTF gets moved (or we do a little multi track drifting?)
Greetings h4ckers! We are again very late in the month and we haven't been doing much in September (some of us were at ACSC, some of us were at BalCCon), but we do have some important info! Namely we have FAUST CTF coming up this weekend, and it's A/D! 2026-09-26: FAUST CTF, an Attack/Defense CTF. The CTF starts at 14:00 our time, so we will slowly meet around 12:00, finish setting up infra and grab lunch....

Greetings hackers, here's to hoping everyone is enjoying the summer so far with temperatures not (yet) as extreme as June.
