Writing a Self-Mutating x86_64 C Program

The post explores writing a self-mutating x86_64 C program, highlighting the complexity and risks involved in self-modifying code, which changes its instructions during execution. It explains how to change runtime code by altering memory permissions using the mprotect() function in Linux and provides an example of modifying a simple function. It emphasizes that while this practice is mostly academic, it is useful for understanding low-level programming concepts and can serve as a defense mechanism in malware.
