This challenge was the first crypto challenge of the Junior CTF 2016.
First, it's pretty easy to know that the flag is encoded in shapes in the bottom left of this picture. But the question is, how to translate/decode it ?
Go on Google Image and proceed at a picture search...
We find this link : http://gravityfalls.wikia.com/wiki/Nightmare_Head/Gallery
So, this capture come from Gravity Falls... Let's navigate on the wiki...
A page is talking about a list of cryptogram, interesting :smirk: (http://gravityfalls.wikia.com/wiki/List_of_cryptograms)
Oh ! In Bill's symbol substitution cipher we find shapes that are on the picture ! (http://gravityfalls.wikia.com/wiki/List_of_cryptograms#Bill.27s_symbol_substitution_cipher).
If we replace shapes by letters we find the following text : FIXPROBLEMQUICKLYWITHGALVANIZEDJETS.
Flag : FIXPROBLEMQUICKLYWITHGALVANIZEDJETS :tada:
