Fedora or Ubuntu might be the easiest to use with either of those options if you have no experience with the linux operating system. If you are not linux savvy and still want to play around with OutGuess, you can use a VM or you can boot most linux distros from a LiveUSB or LiveCD.

While there are official executables for Windows operating systems, OutGuess rebirth doesn’t work with 3301’s JPEGs. To run outguess, you need a linux operating system. Consequently, the compression level of an image may give a clue about the presence of outguess, but this is not enough to draw any conclusion. When creating the new JPEG, the default compression is 75 and can be set using -p to a value between 75 and 100. Outguess creates a new JPEG statistically equivalent to the one given as an input. Before embedding data into an image, OutGuess can determine the maximum message size that can be hidden while still being able to maintain statistics based on frequency counts." As a result, statistical tests based on frequency counts are unable to detect the presence of steganographic content. "For JPEG images, OutGuess preserves statistics based on frequency counts. It detects only OutGuess up to version 0.13. However with 3301’s signature JPEGs with white text on a black background, you can find artifacts it produces very easily with visual inspection alone.ġ StegDetect is useless. Under certain circumstances, OutGuess is considered undetectable 1.

OutGuess is one of many steganography applications.ĭeveloped in Germany in 1999, OutGuess is available under a BSD software license and is completely free for all users. Without this hint, the solvers may not have found or used the program.

Looks like you can’t guess how to get the message out” was their way of hinting at the steganography program OutGuess. You can read about how they got to these images in the ‘What Happened: 2012(part 1)” article. This line was the first hint 3301 gave to solvers, telling them that they were using steganography to hide information. They were very literal when they said: “There is a message hidden in this image”. This was the first time they made contact with the world, and the first time they used the steganography program OutGuess.
