Decrypt GIF to extract coordinates
January 26th, 2014
GPS Coordinates were somehow hidden withing this file. I need to extract the coordinates to play an GPS based treasure hunt game. However, I am stuck on this puzzle.
Has anyone got a clue?
Thanks!

Have a look at that post and ask the guy there, as he had the same question (and picture) and found the answer, too bad he didn’t say how he found it, but I guess you could contact him
This is how you gonna decrypt it…

Images typically use either 8-bit or 24-bit color. When using 8-bit color, there is a definition of up to 256 colors forming a palette for this image, each color denoted by an 8-bit value. A 24-bit color scheme, as the term suggests, uses 24 bits per pixel and provides a much better set of colors. In this case, each pix is represented by three bytes, each byte representing the intensity of the three primary colors red, green, and blue (RGB), respectively. The Hypertext Markup Language (HTML) format for indicating colors in a Web page often uses a 24-bit format employing six hexadecimal digits, each pair representing the amount of red, blue, and green, respectively. The color orange, for example, would be displayed with red set to 100% (decimal 255, hex FF), green set to 50% (decimal 127, hex 7F), and no blue (0), so we would use "#FF7F00" in the HTML code.
And so on, so on…
Could be a text file embedded into the .gif. I’ll have to check it out later on.
Thank you for your messages!
What I forgot to mention earlier is that the name of this puzzle is “=€=” and that a clue was given: 5
@Metroid: I wrote a message on the forum which you gave me, thanks! Hopefully he will write back!
@wo_0t: thanks for your interesting article, however, I don’t think steganography is the method used in this case.
@ gilly : please let me know if you find a txt in the gif! Thanks!

No text file in the .gif I didn’t have winrar on the puter I was using earlier on to see.
This is gonna bug me all day now, lol.
*Edit –
From that French guy’s post linked above, he says there are 20 colours in it.
I know right. I have never come accross anything like this before and it’s driving me insane.
On another forum someone suggested a HEX editor… do you know anything about how that works?
