I'm new to steganography and have been trying to figure this one out but some additional help would be appreciated. There is this image here:
It supposedly has a hidden message in it that should lead to the private key to an Ethereum wallet that has 1 Eth in it. A private key for an ethereum wallet is a 64 hex character string. If anyone helps figure this puzzle out I do not care to have the prize, I have just spent many hours on this with no luck and would like to know how to solve it.
Here is what I know so far:
fileon the image yields this: PNG image data, 1600 x 1105, 8-bit gray+alpha, non-interlaced. So it has no RGB values, just gray and alpha.
- There are only 434 pixels with an alpha value less than 255. I'm pretty sure this is where the solution lies but after this I have no luck.
- I have tried a lot of different things ranging from playing with the bits for both the gray and alpha values for the pixels that have an alpha < 255. Converting them to ASCII and hex, reversing them, only looking at the least significant bit.
At this point I am at a loss. Any ideas?
