Hello Everyone,

I hope you are doing well.

I hope that you have tried all the possible ways to solve the challenge and you are here because you have still not found the solution.

Flag Format: picoCTF{FLAG}

Challenge Details:

The Numbers File:


If we have a closer look at “The Numbers File” we can see that there are some curly braces {}. This gives me hint that its resemeblling the flag in numerical way.

The Flag format is picoCTF{FLAG}, so in this case we can say that

p = 16

i = 9

c = 3

o = 15

C = 3

T = 20

F = 6

So I made this patterns in notepad where all the alphabets are matched to 1 to 26 numerical.

This give out as flag as shown below.


Please let me know if there are any concerns.

Thank You.
