Foremost is a program that recovers files based on their headers, footers, and internal data structures. I find it especially useful when dealing with png images. You can select the files that Foremost will extract by changing the config file in **/etc/foremost.conf.**\
It can be installed with `apt`, and the [source](https://github.com/korczis/foremost) can be found on Github.\
If you find that a **text line** is **bigger** than it should be, then some **hidden information** could be included inside the **spaces** using invisible characters.\
To **extract** the **data**, you can use: [https://www.irongeek.com/i.php?page=security/unicode-steganography-homoglyph-encoder](https://www.irongeek.com/i.php?page=security/unicode-steganography-homoglyph-encoder)
Use [**Trickest**](https://trickest.com/?utm\_campaign=hacktrics\&utm\_medium=banner\&utm\_source=hacktricks) to easily build and **automate workflows** powered by the world's **most advanced** community tools.\
Steghide is a steganography program that hides data in various kinds of image and audio files. It supports the following file formats : `JPEG, BMP, WAV and AU`. It’s also useful for extracting embedded and encrypted data from other files.\
It can be installed with `apt`, and the [source](https://github.com/StefanoDeVuono/steghide) can be found on Github.\
**Useful commands:**\
`steghide info file` : displays info about whether a file has embedded data or not.\
`steghide extract -sf file [--passphrase password]` : extracts embedded data from a file \[using a password]
Capable of a wide variety of simple and advanced tricks, this tool can check file metadata, create transformed images, brute force LSB, and more. Check out `stegoveritas.py -h` to read about its full capabilities. Execute `stegoveritas.py stego.jpg` to run all checks.
Sometimes there is a message or a text hidden in the image itself that, in order to view it, must have color filters applied, or some color levels changed. Although you can do that with something like GIMP or Photoshop, Stegsolve makes it easier. It's a small Java tool that applies many useful color filters on images; In CTF challenges, Stegsolve is often a real timesaver.\
You can get it from [Github](https://github.com/eugenekolo/sec-tools/tree/master/stego/stegsolve/stegsolve)\
Hide, and check for, information encrypted with AES-265 in sound files. Download from [the oficial page](http://jpinsoft.net/deepsound/download.aspx).\
To search for hidden info, simply run the program and open the sound file. If DeepSound finds any data hidden, you'll need to provide the password to unlock it.
Sonic visualizer is a tool for viewing and analyzing the contents of audio files. It can be very helpful when facing audio steganography challenges; you can reveal hidden shapes in audio files that many other tools won't detect.\
To convert binary "1"s and "0"s to a proper image: [https://www.dcode.fr/binary-image](https://github.com/carlospolop/hacktricks/tree/32fa51552498a17d266ff03e62dfd1e2a61dcd10/binary-image/README.md)\
