Hiding Data in Plain Sight

Wednesday, March 4th, 2009

I had a breakfast meeting today with a company involved in forensic reconstruction of data after a possible crime had been committed.  Somehow the conversation shifted slightly and we talked about the process and one of the people said, “You know, it wouldn’t be so bad if we didn’t have to wade through all that spam and not find anything worthwhile in the email messages that showed how the person communicated.”

At this point I said, have you ever thought that they could be using Spam Steganography?  Eyebrows were raised, the conversation paused and I was met with a blank stare for about 30 seconds.

The assumption is that encrypted data needs to look like encrypted data or a string of numbers and letters that are unintelligable.  While this system doesn’t really produce well hidden data, the premise is valid.

I now wonder if they will be redoing that investigation looking for stegonagraphically encoded spam.
