How to hide data in audio file like Mr. Robot – Steganography

You may have watched the popular show Mr. Robot and you were also shocked to know that data can even be hidden in the audio file which was shown in the show Mr. Robot. In the technical term, the methodology of hiding the data in audio file is called steganography. So, let’s look what actually the steganography is and we will move to our topic, How to hide data in audio file like Mr. Robot .

What is steganography?

The art of hiding a message inside another message( for eg : to hide data in audio file ) or a physical item is known as steganography. In computers and electronic contexts, a computer file, message, image, or video is hidden inside another computer file, message, image, or video. Hidden messages are frequently disguised as images, articles, shopping lists, or other cover text (or seem to be part of). It could be tucked away in the margins of a personal letter. Because the secret message does not draw attention to itself, steganography is preferable than cryptography alone.

Plainly visible encrypted messages, regardless of how difficult they are to decrypt, attract attention and may be unlawful in nations where encryption is prohibited. The content of a message is the only thing that cryptography protects. Steganography is the process of concealing both the fact that a secret message is being transmitted and the content of that message. The practice of hiding information in computer files is known as steganography. A transport layer, such as a document file, an image file, a program, or a protocol, may contain steganographic code. You can use large media files to send something using steganography. A sender might, for example, start with a picture file and modify the color of every hundredth pixel to match a letter in the alphabet before sending the image. The difference is so minor that it will go unnoticed by someone who isn’t looking for it.

Use of Steganography in Mr. Robot

Using complicated passwords for your online accounts may be something you’ve done for a long time now. As a general rule, passwords that include lowercase and uppercase letters as well as digits, special characters, dictionary words, and other things are thought to be strong. In order to remember these passwords, you end up saving them in sheets or plain text files, which isn’t the best way to do it. Some of your personal photos or business plans might be on your hard drive. You don’t want anyone else to see them, so make sure they’re safe. If you don’t want your computer data to be found but want to keep it hidden in plain sight, you can use steganography tools.

Mr Robot

Steganography is a way to hide data that uses graphics, music, and video to do it. If you’ve seen the movie Mr. Robot, you may have wondered how Elliot, our brave and heroic hacker, keeps all of his important information on DVDs (not a spoiler). There are people who haven’t seen the show yet. They should start right now. A steganography app called Deep Sound lets you hide any kind of file in audio formats like flac, mp3, wav, and wma. Elliot uses it in the episode. We’ll talk about how you can follow Elliot’s example and go the extra mile to hide your information, just like he did.

So, let’s look at one of the most popular steganography tool Deep Sound and how to use it.

DeepSound – Audio Steganography Tool

DeepSound is an audio steganography tool and a tool to change audio. In audio files, it hides secret data. You can extract secret files from audio files or from audio CD tracks with this tool. This audio steganography tool can be used to put copyright notices on wave, flac, wma, ape, and audio CDs. It can also be used to conceal the copyright notices. To make sure people don’t take your music.

DeepSound can also use AES-256 (Advanced Encryption Standard) to make secret files more secure.  The app also has a simple Audio Converter Module that can change a number of different audio formats (FLAC, MP3, WMA, WAV, APE) to other formats. This module is very easy to use (FLAC, MP3, WAV, APE).

How to use DeepSound Audio Steganography Tool

Follow the steps:

  • Click or drag and drop an audio file (flac, wav, wma, mp3, ape) to the Carrier audio files list to open carrier files (F2). You can also open carrier files by clicking or dragging and dropping.
  • Click “Add secret files (F3)” or drag and drop them into the “Secret files” list at the bottom of the app to add them.
  • To do so, hit F4 or click the tool bar’s “Encode secret files” button.
  • You have the option of determining how the audio will be produced (wav, flac or ape). DeepSound does not support the wma output format. This is how you can embed secret data in an audio file and then use an external tool, such as Windows Media Encoder, to convert the wav file to wma, which is lossless audio.
  • When you enter the ‘Encrypt confidential files’ dialog box, you can toggle AES-256 encryption on and off. The modified audio file will be saved in the output directory. Go to Settings if you want to modify where the output goes.
  • When you press the “Encode hidden files” button, the audio file begins to conceal secret files.

OpenPuff – Alternative to Deep Sound

Even though DeepSound hasn’t been updated in a long time, it still offers all of the audio steganography tools you’ll need. This program does not allow images to be concealed within files. It also does not create videos from other types of files. On the Internet, you’ll find tons of image steganography software. However, having a tool that can accomplish everything is preferable.

OpenPuff can be easily downloaded from the internet. It’s a steganography tool that’s open source. Images, audio, video, and flash files can all be hidden using it. It uses about 16 different multi-cryptographic algorithms for encoding and has many layers of protection. As a result, OpenPuff can now be used as a professional steganography tool. Use this tool to encode secret files into audio and video files, as well as to embed messages in photographs. This allows you to hide your files in a variety of file formats.


That’s all there is to it. That isn’t entirely correct. There are also different methods for concealing files in media formats. It’s not simple to locate decent software, but with DeepSound and OpenPuff, you’re already on your way to being a competent steganographer. There’s no doubt that you and your pals already exchange a lot of music, photos, and movies. You can now use them to store your own secret files.
