This challenge was Forensics Category challenge in CyberSpace CTF 2024 in this challenge we were given a .DAT name ( cat CCLocalLevels.dat) file which was the data of the Geometry Dash.

  1. First cat the file then after i tired with the strings
  2. Then i tried with the binwalk still didn’t got anything

So, i google it to execute the .dat file which was provided by the author.

Then i found this link : https://gdcolon.com/gdsave/

After that i downloaded the the file in JSON format, in the JSON file what i got was the author name on it.
