The Cyberlypics is a global CTF (what one isn’t, really?) with a $60 entry fee. The finals are in The Netherlands. Beyond that, it’s nothing too special.

We did our pre-challenge challenge last night over some stupid registration stuff.

We finished 83d, and most of the challenges were pretty lame.

Heard from my friends that it wasn’t a good CTF xddd Y’all got trolled :joy:


(Full Snack Developer) #13

I got 60% or more of my flags from strings and grep.


(Full Snack Developer) #14

And I kept finding flags or pieces of flags all over the place but had no idea what challenge they went to. Also, the platform was unstable as all get-out. Kept going down on us, timing out, crashing, leaderboard never worked.

We wanted to use my Legobot to check the score, so I actually managed to scrape the leaderboard before we started with probably the lamest “hack” ever. I tried to use Python requests + bs4 to pull and parse the leaderboard, but got 403’d. I just set my user-agent to something Firefox and it let me through.

Daaaaaaaayuuum :rofl:

Seriously its Bad CTF No Reverse Engineering No Pwn … :cry: and not free like Others :rage:


(Full Snack Developer) #17

There was a tiny bit of reversing, but noting very serious. I solved half the reversing stuff by just doing a strings. Seriously.
