mrcrypt's DC610's 2023 Pub Crawl CTF steganography challenge
Rik's Apple Solution

RiksApple is a steganography puzzle box referencing The Young Ones episode, "Flood".

Rik is angry the half of an apple he was saving is missing from their refrigerator. He confronts Mike and Vyvyan about it. Text on the image reads: VYVYAN'S HIDDEN RIK'S HALF AN APPLE, BUT WHERE... OR WITH WHOM?

The first clue is the word "HIDE" in the text of the image. This is meant to imply using steghide to solve a part of the puzzle.

The second clue is hidden in the white space of the image under the text.

A stegsolve output image with 'No Comment' showing under the already visible text.

"No Comment?"

Of course!

screenshot of Exiftool output in terminal. The Comment image tag is highlighted with yellow to call it out.

In the Comment tag is a string encrypted in base32. Decode for the steghide password and capture the flag.

THANK YOU FOR PLAYING!
