After introducing memory virtualization technology, there are three types of addresses in the memory system. Machine Address (MA): The real hardware machine address, visible on the address bus as address signals. Guest Physical Address (GPA): The pseudo-physical address seen by the virtual machine after abstraction by the VMM. Virtual Address (VA): The linear address space … Read more
One Introduction A long time ago, I saw a post that used the Frida API. Process.setExceptionHandler(callback) to implement memory read/write breakpoints. However, since the mprotect function can only modify the memory attributes of an entire page, it is not very useful for specific addresses. I had difficulty finding the core code while reverse engineering games, … Read more
