You can always use the various shorteners... e.g. http://url.drogon.net/o This isn't news though - first reported a couple of weeks ago: http://www.theregister.co.uk/2011/04/26/cluster_based_steganography/ but the original paper is about a year old.. http://www.sciencedirect.com/science?_ob=ArticleURL&_udi=B6V8G-51BBKRS-1&_user=10&_coverDate=01%2F31%2F2011&_rdoc=1&_fmt=high&_orig=gateway&_origin=gateway&_sort=d&_docanchor=&view=c&_acct=C000050221&_version=1&_urlVersion=0&_userid=10&md5=ee913861b3d05b46b905bd4d52ca9380&searchtype=a#sec8 or http://url.drogon.net/p
An open source project into Steganography - hiding information in "plain sight". Might be of interest....
It's interesting, but not that it only works on FAT32 filesystems and simple operations like defragging the disk will lose the data...
Also, something like fgrep -i "bin laden" /dev/sdamay still find what your looking for. Harder to grep for images though, but there are tools to find fragments of images, headers, etc. given a raw disk device.
This may be of interest if you're interested in this sort of thing: http://www.truecrypt.org/ Gordon -- The Mailing List for the Devon & Cornwall LUG http://mailman.dclug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/listfaq
