Peter Honeyman and Niels Provos from UMich's Center for Information
Technology Integration have successfully extracted a hidden image from
a sample JPEG image. That sample JPEG was featured in a recent ABC
News report about steganography:

No, the image wasn't created by bin Laden & com, but it's an
interesting demonstration nevertheless. I dislike sending out
attachments, so I've placed the extracted image here:

Subject: first steganography trophy

Ducan Campbell, author of an interesting article for telepolis,
informed Peter and me about the ABC coverage concerning steganography.
Here is part of his message:

   During the broadcast (transcribed here at the end), Mr Hosner
   displayed a jpeg image which can be found at
   http://www.wetstonetech.com/sovereigntime.jpg. It is also attached
   to this mail.  He asserts that it contains a steg image of a B52.

Peter suggested to use my stego tools on it.  No problem:

$ stegdetect sovereigntime.jpg
sovereigntime.jpg : jsteg(***)
$ stegbreak -tj -f wordlist sovereigntime.jpg
Loaded 1 files...
sovereigntime.jpg : jsteg(abc)
Processed 1 files, found 1 embeddings.
Time: 1 seconds: Cracks: 1156,   1156.0 c/s

The secret key is "abc."  And the hidden message is an image of an
aerial view of a military airport.  I attached it.

Actually, this is the first real hidden message that we have found.
