Any hint for not_art

@McBlocked said:
well it can be hidden within LSB and checked

it could be hidden with LSB. I honestly haven’t solved it yet, but the idea had crossed my mind yesterday and I started digging into it. It could also not be hidden with LSB.

So this is a stego challenge, how many different ways can a message be hidden in a picture?

i do not think that there is a good estimation for that.
looking into challenges here some can be really unique.
and may require different ways of processing until you figure out the way the flag is hidden

This is also very much true. Also the question was rhetorical, but it makes you think and may turn up something else. I checked out two color-related programming langs, but they both turned up nothing. I moved to checking byte differences, which may result in google searches. Just throwing ideas around, trying to figure it out, myself.

Sounds good to me lol.

It’s not like i’m gonna share the whole script :slight_smile: And that’s a reasonable hint to start :slight_smile:

Not expecting that. Where’s the fun in sharing entire scripts?! lol. It’s a hint. A very vague one since this could be any number of image manipulating scripts, but it’s a hint. Enjoy the challenge, everyone!

Think in threes.

i got the some binary. but can’t decode. any one give some hint my path is correct or not.

I’m only almost there only that last step I think :flushed:

wow. this has probably been my favourite challenge

Please - can someone give me a hint. I’ve tried unraveling it - and looking at the RGB values. Rotating the RGB values… I’ve put it into every steg software I know about… What am I missing!? I’ve tried stereogramming the image. Inverting the image and overlaying it… ARHGHGHGHG.

I’m a bit stuck on this myself and would appreciate a nudge. I see the hints such as “think in threes” and the like, but I’ve been unable to discern anything meaningful from the RGB values. I’ve tried converting the values to and from different base encodings, and I’m just not getting anywhere. Am I overthinking it?

It took me a while to figure this challenge.
Using the RGB values you only get 3 different values, this is similar to a base. From there Check the min and max values you can get converting from that base to decimal. Once you see that number you’ll understand next step.

Got it!

Really fun challenge! Feel free to PM me for hints.

Best question I ever solved!

I’m stuck on this challenge! Can i PM someone for hints ?!

I had tried npiet not_art.png

But …
What is missing…

Hack The Box

Please help!

Stuck on Playing with the color channels - noticed some differences between planes and the gray bits - Would appreciate a hint via PM

This took me a long time, and I definitely wouldn’t have done it without some helpful hints in this thread.

I’d like to compare methods with anyone who has a more automated solution. I did a lot of work by hand that I know I could’ve programmed but couldn’t quite get it.
