Intro to Reverse Engineering, Part 2
How To Patch Binaries For Hackers And Pen Testers
Last time, we talked about how to reverse engineer a binary using Ghidra.
But what if you wanted to make modifications to the binary itself?
The process of making changes to a binary and modify its instruction flow is called “patching a binary”. Hackers do this to bypass built-in protections, or to make the program behave in a different way to make the exploit development process go more smoothly.
And today, let’s talk about how to do this directly in Ghidra!
Crash Course Assembly
To patch a binary in Ghidra, you first have to gain an understanding of assembly language.
When a computer is executing code, it only understands machine code instructions. An executable binary is in this form.
Assembly language refers to any low-level programming language where there is a strong correspondence between the instructions in the language and the…
