Niels Provos (U. of Michigan) has a very interesting paper on detecting
steganography on the network (he talked about it during the USENIX Sec. WIP
session). Basically, he didn't find any steganography in about 2 million images
he tested on Ebay. He's working on doing the same for other mediums/sites.
As the paper has not been published yet, I don't want to give more details. I've
cc'ed Niels on this message, so perhaps we'll get a summary of his latest
results.
