Does Kali Linux forensics tool help in detecting hidden files in images or audio files ?
stegsecret, I don't know how old it is though. Just google steganalysis tools
I did my search but did not find a good tool to detect information inside the media files
I came across stegdetect whilst answering questions for C|EHv9. Idk how trustworthy it is though.
Here is a good list of tools.
