티스토리 뷰
you can see that page when you click 'join now' button.
the hint was not helpful for me.
first, use web browser developer tools and go console section.
I entered "makeInviteCode()" it was just my attempt.
then you can see the codes of that function.
you can get some 'data' encrypted. and also encryption type maybe ROT13. i think, it can be different by case.
so now decode the data with encryption type.
then you can get the other hint how to get invite code.
I used 'curl' command to make post request -> curl -X POST urlurlurl
then you can get some 'encoded' data
now if you access the site again and enter "makeInviteCode()" on console command again, maybe you can find out differences.
the encoded code you got can be decoded by the 'new' encryption type.
finally it is your invite code to thehackbox.
you can join in the hack box ! congratz
