Announcing the release of Anti-Steganography (AntiSteg v1.10):

antisteg110.zip AntiSteg 1.10: Anti-Steganography

*** Now with AVI file support.
v. 1.10 Replaces v. 1.00 ***

AntiSteg is a command line tool for cleaning images and widely
used AVI files of potentially harmful steganographical content.
Many popular image formats (several dozens, and especially those
used and distributed on the Web) are handled by the tool.

Steganography is a means by which information is hidden inside
of images/avi movies (often via high-encryption algorithms),
making them completely invisible to all standard image viewers/
movie players. Stegged images/movies can carry extremely harmful
payloads, which include, but are not limited to:

- Child pornography/Snuff movies
- Viruses, Trojans, Spyware, Spamware, and other Malware
- Sensitive personal/corporate Data

AntiSteg does not attempt to extract the actual hidden data,
but simply antistegs the content, making it impossible to be
retrieved at a later point in time.
This approach allows it to quickly clean a computer, even if
100,000s of images are stored on it. In contrast, trying to
desteg just one image, which uses a high encryption encoding
(256 bit or higher), and a properly selected password is
computationally nearly infeasible. To attempt the same on an
AVI movie is not even worth mentioning!

AntiSteg has been tested on hundreds of thousands of images and
successfully applied to antisteg pictures created by dozens of
freely available steganographical image and AVI tools.
Some of these tools have been widely spread via commercial CD/DVD
distributions. These distributions in turn, have been put forth
by several well known Computer Magazines which have a worldwide
audience. Put simply, steganographical tools - to hide images
and complete movies - are widely spread and come in many different

Since the amount of images stored on the Web approaches staggering
numbers (anywhere from 100s of billions to trillions), the
possibility to successfully store and trade/sell child pornography
(snuff movies), distribute viruses, or exchange sensitive
information is very high. Even worse, anybody who operates a web
site (personal or corporate) that contains images may unwittingly
be helping pedophiles, black-hat hackers, or data spies in their
operations. Of course, the same holds true for any e-mail
attachment, or MMS being sent!

Currently available antivirus, antispyware, and antimalware tools
do NOT address this problem!
Companies that allow image specific searches - like Google - do
NOTHING to prevent stegged images from being spread via their

AntiSteg is the ONLY available and WORKING tool that effectively
deals with this problem. And best of all, it's FREE!
