Problem
This garden contains more than it seems. You can also find the file in /problems/glory-of-the-garden_3_346e50df4a37bcc4aa5f6e5831604e2a on the shell server.
Hint
What is a hex editor?
Solution
Given the hint that we should be using a hex editor, open the image in one 😝
I'd recommend ghex
as it's very user friendly for beginners.
$ sudo apt-get install ghex
...
...
$ ghex garden.jpg
and find your flag by scanning the whole hex dump 😊 or you could use strings to find the flag.
$ strings garden.jpg
...
Here is a flag "picoCTF{more_than_m33ts_the_3y35a97d3bB}"
