Stego learning

Someone can address me to some tutorial useful to learn some stego and how to do the stego challenges?

Google about “Stego challenges/CTF’s write-ups/walkthroughs” …

https://pequalsnp-team.github.io/cheatsheet/steganography-101

Not a tutorial as such, but a collection of pointers and tools you could use. Tools/commands of particular note for the challenges I’ve done so far are strings, xxd, binwalk, steghide, stegsolve, sonic visualiser

Thank you very much!

Thanks for this
