![]() These numbers were the length of the original pictures, which were then multiplied by 3301 to get the URL of a webpage. This led to a voicemail prompting users to find two set of numbers. The image appeared to be a dead-end until someone used the Outguess program to reveal a hidden message that took users to a subreddit and then to a book that contained a phone number when deciphered. It was an image posted on 4chan that declared the group was looking for talented individuals to welcome to their team.Īt first, people thought that someone was trolling them (it was posted on 4chan after all), but then a user used a text editor to view the image and found out it included a code to another image. The first clue of the puzzle appeared on 4th January 2012. The BeginningĬicada 3301 is arguably the best-known Internet puzzle that garnered the biggest amount of attention online. We’ll discuss these puzzles and the theories surrounding them. Many people still wonder what their purpose is and who’s behind them, which, as you can guess, has also created a plethora of fascinating conspiracy theories about them. Some of them were solved, while others still await this moment. Today we are going to talk about our favourite Internet mystery or the elaborate puzzles given by Cicada 3301. Outguess -k "secret2" -e -r out.jpg message.The Internet is full of mysteries despite its relatively young age. The second message hide2.txt can be retrieved with Outguess -k "secret1" -d hide1.txt -E -K "secret2" -D hide2.txt monkey.jpg out.jpg Outguess will first embed hide1.txt and then hide2.txt on top of it, using errorĬorrecting codes. ![]() ![]() If you want to embed a second message, use: Will retrieve the hidden message from the image. Outguess -k "my secret pass phrase" -r out.jpg message.txt Outguess -k "my secret pass phrase" -d hidden.txt monkey.jpg out.jpg To embed the message hidden.txt into the monkey.jpg image: Outguess operates as a filter and assumes the PPM data format. Outguessĭetermines the data format by the filename extension. Repeated use increases output level.įor embedding messages, you need to specify a source and a destination filename. t Collect statistics about redundant bit usage. The higher the quality the more bits to hide a message in the data are available. For the JPEG imageįormat, this is the compression quality, it can take values between 75 and 100. Passes a string as parameter to the destination data handler. If the second key does not create an iterator object that is successful inĮmbedding the data, the program will derive up to specified number of new keys. If this option is not specified, outguess r Retrieve a message from a data object. Other options that apply to the general execution of outguess: eE Use error correction for data encoding and decoding. Specify the upper limit for finding an optimal iterator seed. Without searching for a more optimal embedding. If no upper limit is specified, the iterator will use this seed Specify the initial seed the iterator object uses for selecting bits in the Specify the filename containing a message to be hidden in the data. Specify the secret key used to encrypt and hide the message in the provided data. Result, no statistical test that is based on frequency counts will be able toĭetect steganographic content. Specifies that OutGuess should preserve statistics based on frequency counts. The following command line options, when specified as capital letters, indicate options Artifical errors are introduced to avoid modifying A (23,12,7) Golay code is used for error correction to It keeps track of the bits that have been modified Value, and tries to avoid the modification of bits that were extracted from a low value.Īdditionally, Outguess allows for the hiding of two distinct messages in the data, thus By altering the seed, outguess tries to findĪ sequence of bits that minimizes the number of changes in the data that have to be made.Ī bias is introduced that favors the modification of bits that were extracted from a high The data along with the rest of the message. A seed can be used to modify the behavior of the iterator. Outguess uses a generic iterator object to select which bits in the data should be PPM, PNM, and JPEG image formats are supported, although outguess could use any kind ofĭata, as long as a handler were provided. Will extract redundant bits and write them back after modification. The program relies on data specific handlers that Information into the redundant bits of data sources. x maxkeys ] ]ĭESCRIPTION Outguess is a universal steganographic tool that allows the insertion of hidden
