So few days ago going through youtube Reverse Engineering videos, i came across a particular video where an android application was modified using IDA pro by disassembling it's .so file found in /lib directory in every android app.
This is the link to the video https://m.youtube.com/watch?v=m-t-jFBy7FE
I was further curious as i have never seen anyone modify an android App from the .so file usually when we talk of reversing android apps we use tools like Apktool, Dex2jar, jd-gui and so on.
What kind of Reverse Engineering is this and what exactly is going on???
Someone please shed some light on this topic. i've been confused for days.
