Ptrace-based Library Injection 💉 (my first personal project at Worri coffe XD)

"Why ask for permission when you can just... inject?"

Why I make this?

• I want to improve my understanding on some injection techniques ( ptrace is a good reason to learn & start). Besides, I could enhance my coding skills as well.

• Furthermore, hopefully after this simple project, I could contribute (or create?!?) something to modify Frida for stealthy evasion against some detection mechanisms, or even make something crazier!

• Contact me if you have the same sense of purpose ;)
