I have recently read malware being hidden in a "usable" picture file with stenography such as this forum, https://www.bleepingcomputer.com/forums/t/574487/is-it-possible-for-a-virus-to-be-embedded-in-a-image/ .
Could a malicious hacker use similar methods on an audio file?
There are similar questions on various sites about malware in an audio such as this, https://forums.malwarebytes.com/topic/140812-can-an-mp3-file-contain-malware/, but my question is specifically related to the tactic of steganography.
