This is my last stego and I am really stuck here. I am trying to find the “different” pixels and so after getting the values as in “not_art” I used sql to find the unique values. Now I have got an excel with the values and I can guess some of them are almost “funny” but I don’t know what to do with them.
Thank you N30C0UNT with your help I finally managed to solve it. That was heck of a challenge.
just a quick one to get my bearings,
Am i looking at a custom LSB algo
or
something else like Not_art that i need to do something with the values??
if this is a spoiler plz feel free to PM me.
Would very much appreciate a nudge, I believe I am on the right track, I’ve come up with 2 groups of pixel values, and have taken notice of the edges of the image. Not quite sure what to do with the values I got, it seems like I have so many leads but just can’t figure out the last step.
Hello, I am very confused with this challenge … I used a script called check_png.sh and I was able to see a lot of metadata and apparently there is a file (PGP \ 011Secret Sub-key -) but I don’t know how I can try to remove it. I’m a little lost … Could someone please help me?
I’ve identified 2 different types of pixels by values. I’ve tried converting the RGB values in all sorts of ways and I’m just not able to come up with anything.
A phenomenal challenge! This is my first Expert challenge ever. Took me four hours with the hints here. I’m sure those of you that found the flag at first release had a heck of a time figuring this one out.
If you’re on page two of the hints, go back and read what you have.
My hint?
I recommend attempting other challenges by the same creator before attempting this one.
