You can have a look at something like https://github.com/shellphish/how2heap or https://ctftime.org/writeups

Hi everyone, I just started messing with heap overflow and I've been reading how2heap's house of force technique but something doesn't make sense.

https://github.com/ReFirmLabs/binwalk/wiki/Quick-Start-Guide here's how to extract firmware

If you can get them attached to something, I wouldn’t bother trying to mount then, just dump the contents and use something inker binwalk to figure things out and see if it can extract things.

With that said, I'll repeat what i said last post, run binwalker on the image. Nothing that anyone is saying here is probably going to work because that doesn't have any features of an FS image

Op, run binwalk. Don't just run it though an hex editor, you won't understand anything. It's a forensics tool to analyze unknown binary blobs (much better than gitbash that someone mentioned). It can also unpack these files automatically, there's no better universal tool for it

Not sure if it would be easier or not, but you could also use binwalk to find a binary string in a file.

Not true, it's still not patched. See https://github.com/ReFirmLabs/binwalk/pull/617

Looks nice! Kind of reminds me of binwalk: https://github.com/ReFirmLabs/binwalk
