#steghide: Steganography tool for hiding text in image and audio files

This application is ancient (see: SourceForge) but it is still maintained by the Kali linux community and is available via common package management sources (apt etc).

While I don't have any common use case for this, I always thought the idea was neat. Basically, use the tool and a password (shared secret) to embed a message within the bits of an image or audio file. Unless you know something is in the file, the message is well disguised. On the other end, use the tool and the shared secret to extract the message. Voila! You're doing #Steganography .

Bonus puzzle: See if you can figure out which files on this page have a hidden message, using the password "somethingsecret": https://coreysnipes.com/media-test.html

FOSS Advent Calendar - Door 5: Hiding Secrets with Steghide

Today we explore Steghide, the classic command line tool for steganography. It is used for hiding data inside files.

Steghide allows you to embed secret messages, images, or any other data into cover files such as images or audio files. It works by cleverly hiding information within the color channels of images, making it invisible to the naked eye. Only someone with the correct password can extract the hidden data.

This tool is perfect for nerdy experiments, privacy enthusiasts, or simply for impressing friends with secret messages.

Pro tip: try hiding a small text file inside a JPEG image and then extracting it again. It feels like terminal magic!

What secret would you hide with Steghide?

WebP: Идеальный хамелеон? Разбор формата и LSB-стеганография в режиме Lossless

Всем привет! Мы продолжаем наш цикл статей, посвященный практической стеганографии в самых, казалось бы, обыденных файлах. Мы уже научились прятать данные в «слепых зонах» документов MS Office, внедрять «файлы-призраки» в EPUB и даже создавать скрытые каналы данных внутри PDF. В комментариях к прошлым материалам наши читатели справедливо заметили: « А что насчет WebP? ».

#steghide - na LinkedInnie znalazł się dotychczas nikt, kto by po ALT tekst rozkminił, co ukryłem w obrazku - jacy ci hakerzy mocni, potrafią uruchomić Metasploit... a tu znajdzie się ktoś, kto podejmnie to wyzwanie?

#Steghide is a steganography tool.

Steghide is a utility that takes in an input file and arbitrary data and hides the data inside the file. The resulting file can be fed back into Steghide to reveal the original information. Steghide supports images (BMP, JPEG), and audio (WAV, AU). Steghide uses statistically resilient hiding methods and supports encryption and checksumming.
