This does really helps.

change the hight section in hex

somehow i cant get not broken jpeg file after editing hex using xxd. using hex editor is much easier and faster to solve this https://hexed.it/

try - ff c0 00 11 08 11 11 07 E0

learned lots of stuff

thx for the challenge

Tips: The flag is 'outside' the pic, but it still part of the file. Think about dimensions.

I suggest use CyberChef and HexEd

This link will help a lot: blog.cyberhacktics.com/hiding-information-by-changing-an-images-height/

Incredibly helpful.

im comaritively new to cyberchef, how do u "check" images with that?

thanks it was actually helpful

an article that can help: https://www.quora.com/How-do-I-extract-width-and-height-data-from-an-Exif-JPG-hex-format-in-C++

Sooo cool! Learn a lot about jpeg.

I had to fight my way there.

I don't think this should be in the easy section though

Any hint? several people (me included) seem stuck. I have read quite a bit about the jpeg specification, found something about blocks, but nothing helped so far.

Need to read more. Specifically about how does JPEG stores its dimensions.
