The "image" of Steganography

SecurityFocus ran a pretty good article on Steganography that I found interesting. I always wanted to get into steganalysis, cracking all those pr0n images looking for secret messages.

Seriously though, if you know very little about the topic, it's a good read. Explains some of the theory behind covertly hiding information in other files, such as images and mp3, and how to get it out.

Fun stuff.
