antisteg100.zip AntiSteg 1.00: Anti-Steganography
AntiSteg is a command line tool for cleaning images of potentially
steganographical content. Many popular image formats (especially those
on the Web) are handled by the tool.
Steganography is a means by which information is hidden inside of
(often via high-encryption algorithms), making them completely
all standard image viewers. Stegged images can carry extremely harmful
which include, but are not limited to:
Viruses, Trojans, Spyware, Spamware, and other Malware
Sensitive personal/corporate Data
AntiSteg does not attempt to extract the actual hidden data, but
the content, making it impossible to be retrieved at a later point in
This approach allows it to quickly clean a computer, even if 100,000s
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
computationally nearly infeasible.
Since the amount of images stored on the Web approaches staggering
(anywhere from 100s of billions to trillions), the possibility to
store and trade/sell child pornography, distribute viruses, or
information is very high. Even worse, anybody who operates a web site
or corporate) that contains images, may unwittingly be helping
black-hat hackers, or data spies in their operations. Of course, the
true for any e-mail attachment, or MMS being sent!
Currently available antivirus, antispyware, and antimalware tools do
Companies that allow image specific searches - like Google - do
NOTHING to prevent
stegged images from being spread via their services!
