2012 CTF by Fluxfingers
It was again a great moment of fun to participate to this year's CTF organised by Fluxfingers @ Hack.lu 2012
T-Shirt contest
This one is quite apart from the other challenges for several reasons:
- The challenge was actually printed on participants' t-shirts, as of last year
- Surprisingly enough, only 2 teams over the 290 who scored at least one challenge managed to solve it!! (the last team of the top 50 and another one further in the scoreboard
- The challenge was the only one not designed by Fluxfingers team but... by myself, with the help of Alex to design the actual T-Shirt
Still I played the ctf fairly, proof is that even my team didn't find the solution ;-)
I must admit, the challenge was easier for local people than for remote people, reason is that a list of words was written on the T-Shirt while online a patchwork of unrelated images was visible.
On first evening, as no one solved it yet, we added an extra hint in the challenge description.
On last morning, as no remote team managed to solve it, we also published a picture of the T-Shirt for remote teams. Apparently it didn't help...
Here is it:
28 - T-shirt
Same as local T-shirt challenge: https://ctf.fluxfingers.net/challenges/noclue.png
