So I need help on this CTF problem. I feel like I'm doing something really wrong. The hint doesn't make much sense to me because if I mod every pixel by 8, the image becomes black.
Here's the image:
Thereâ€™s an image of some trees here. I bet the image contains more than trees, though.
Try mod 8?
Do you know how the flag looks like? I've found a hidden message, but it doesn't look like a flag to me rather than a hint.
The problem is called "Trees" so I'm pretty sure anything to do with Trees is probably the flag.
WTF Stegsolve is amazing. dont_miss_the_flag_for_the_trees But what does "Red plane" and "Green Plane" mean?
I'm not entirely sure about that. It's a RGB sorcery :o
If someone roughly knows, please ELI5 for us :|
