This was the first time they made contact with the world, and the first time they used the steganography program OutGuess.
#Outguess rebirth portable#
They were very literal when they said: “There is a message hidden in this image”. Outguess-Rebirth is a portable steganography tool for Windows, allows a user to embed hidden data inside a image JPEG. This line was the first hint 3301 gave to solvers, telling them that they were using steganography to hide information.

You can read about how they got to these images in the ‘What Happened: 2012(part 1)” article. Steganography using/detecting Outguess to hide messages in pictures LUKE SLYTALKER 2.56K subscribers Subscribe 6.7K views 3 years ago Quick run-down on how to use Outguess for embedding as well. There are more than 10 alternatives to Outguess Rebirth for a variety of platforms, including Windows, Linux, Mac, Online / Web-based and BSD. Looks like you can’t guess how to get the message out” was their way of hinting at the steganography program OutGuess. Outguess Rebirth is described as 'Outguess-Rebirth is a portable steganography tool for Windows, allows a user to embed hidden data inside a image JPEG' and is an app. Without this hint, the solvers may not have found or used the program.
#Outguess rebirth software license#
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.

While there are official executables for Windows operating systems, OutGuess rebirth doesn’t work with 3301’s JPEGs. 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.įedora or Ubuntu might be the easiest to use with either of those options if you have no experience with Linux operating systems. Under certain circumstances, OutGuess is considered undetectable 1. 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. It detects only OutGuess up to version 0.13. "For JPEG images, OutGuess preserves statistics based on frequency counts. 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. 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. To run outguess, you need a linux operating system. Outguess creates a new JPEG statistically equivalent to the one given as an input. While there are official executables for Windows operating systems, OutGuess rebirth doesn’t work with 3301’s JPEGs. So, Ive been trying to find Outguess, but I have only been able to find Outguess Rebirth, which I am either using incorrectly or is completely useless for Cicada3301. When creating the new JPEG, the default compression is 75 and can be set using -p to a value between 75 and 100. It is used to hide the existence of messages from the third party Key Words Steganography,Receiver,payloads etc. Steganography uses some scientific techniques for hiding message, such as invisible int, microdots etc.
It can even try to decode or bruteforce some of the algorithms.To run outguess, you need a linux operating system. Open puff, openstego, outguess, outguess-rebirth are the other tools using in steganography. For JPG images it is possible to use a tool called Stegdetect to identify images which are suspicious to bare the steganographic content and identify a tool used to hide the message.
