How can steganography be detected?
The easiest way for a SOC to detect steganography is to simply invest in an email security or data-loss prevention tool that has such capabilities built in. All you have to do is point the alerts to your monitoring system and respond.
Steganalysis tools can also be used to detect the presence of steganography: Stegdetect is an open source steganalysis tool that is capable of detecting steganographic content in images that have been generated by JSteg, JPHide, Invisible Secrets, OutGuess, F5, Camouflage, and appendX.

How does audio steganography work?
Audio Steganography is a technique used to transmit hidden information by modifying an audio signal in an imperceptible manner. It is the science of hiding some secret text or audio information in a host message. Embedding secret messages in digital sound is a more difficult process.
The text may look like gibberish, but you only need to focus on what’s at the end to view image as text. Scroll all the way down to the bottom of the text; if there is any hidden text within the image, it will show up there. If the text does not exist in the image, it will not show up on the bottom of the image.
