> AntiSteg is a command line tool for cleaning images and widely used
> AVI files of potentially harmful steganographical content.
> The newest major release, supports cleaning images and AVI's stored
> inside of Windows resource files (i.e.,
> dynamic link libraries, executables, etc.). Resource files are wide
> spread, often shared among programs, and can carry any type of image
> and/or AVI files. Resource files are especially problematic, since
> programs that utilize them, can either directly or indirectly act as
> carriers of code which in turn activate triggers for invoking hidden
> code functions. All of course neatly hidden inside of
> steganographically infected image/AVI files and out of sight of every
> antivirus, antimalware,
> antispyware, etc. computer sentinels.
> Many popular image formats (several dozens, and especially those used
> and distributed on the Web) are handled by the tool as well as
> cleaning images and movies packed inside of archives.
> 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, tens of
> thousands of archives/Windows resource files, 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 flavours.
> 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 services!
> Firewalls provide no security with respect to asynchronous, bi-
> directional steganographical communication via 2 web sites
> (spy site and infected site) and simple web monitoring software
> augmented with steganographical support for modifying images (hosted
> on spy site). Neither heuristic, nor behavior-based antivirus and
> antispyware applications will detect anything unusal since all
> software operations are identical to those performed by 1000s of image
> editing, image viewing, and web site monitoring sofware currently in
> circulation.
> AntiSteg is the ONLY available and WORKING tool that effectively deals
> with this problem. And best of all,
> it's FREE!
> Special requirements: None.
> Distribution : Freeware.
