Pay attention to those strings!
Discussion
yes this problem is easy... this is 'ctflearn.com' so it is for learning... if this problem is too easy for you then try a more difficult one
Cool
easy
easy but you must know one thing that you must know the flag how it must be submitted otherwise it will take your alot time
You only have to pay attention for the right spelling!
My honest criticism is that a don't think a flag should need to be brute forced by giving the user 12 equally valid possibilities.
This is because copying/ pasting each flag isn't really a 'skill' worth practicing or assessing.
I think the exercise could be better if there was a way to identify which of the flags is meant to be correct.
If i've missed something, please let me know.
You have to look at the ctflearn.com website to for submitting a challenge, and then you will see the recommended format for challenge flags, including the case of the flag. The intent was to look at the strings, recognize they are the same except for the case of the letters, and then try to find some way to discern the correct case. But overall I know this is not a great challenge bc almost everyone solves by brute force. I have lots of other challenges, hopefully you will enjoy them more. Try 'The Keymaker', 'Gandalf the Wise' and 'Vargas Island', those more interesting. Cheers.
A mage came to show me to how to do this challenge! Here was the hint
You should see the correct spelling, position, format of all the flags!!!
So Easy just focus on The format CTFLearn guys.
