😭39th / 776 overall - not bad, but again my lack of knowledge in pwn and rev proved how much I need to invest time into these shenanigans.
Total solves of 13 / 27 challenges (zero pwn fk given)
Duration: CTF runs from 4th September 2025 08:30 AM UTC (10:30 AM CEST) to 5th September 2025 11:00 AM UTC (01:00 PM CEST)
This time around, I didn't fully clear the web section, although I was able to solve last one towards the right direction (upsolve time baby).
I still need to learn more about crypto and need to start the pwn tutorials (it's been forever).
The competition had a rating of 30- and was hosted in Berlin, open for everyone online. It's definitely on the weaker end of my understanding due to not having a lot of quality of life features (dockerfile, instancing — which is understandable since the admins were probably afraid of bots... and I know there are people cheating their way through these competitions). But that leads to services sometimes going down and running slow as hell since I'm in the states (want faster connection? VPN or VPS that sh to EU, buddy).
Those downtimes were quite misleading because I got all confused thinking they were part of the challenge tomfoolery, because some dude elsewhere was brute-forcing the hell out of the only instance (shared for all teams).
The challenges are towards black box approach... which is rough, man. Very.
