A Petty Wage in Regret

[!danger]- Answer poctf{uwsp_7h3_w0rld_h4d_17_f1257}

  • first i tried using [[strings]] on the image, but nothing stood out

  • i then used [[exiftool]] and found a user comment which looked suspicious

  • so i put it into [[CyberChef]] and used magic and it was in hex for the first part of the flag

  • the decoded message also said this was half of the flag

  • if you look very closely to image, you can see some sort of distortion, with some looking like numbers

  • i uploaded it to [[FotoForensics]] and used the ELA tool to see the compression levels or smth (checks if the pixels around it are similar color/brightness) to make sussy stuff pop out

  • and there it is part 2 of the flag is visible in the image (combine with underscore)
