Sigreturn-oriented programming
SIGRETURN-oriented programming (SROP) is a technique used by computer programmers to take control of a computer's operating system using very small, simple programs. Think of the computer's operating system like a giant puzzle with lots of different pieces. When we use SROP, we're trying to rearrange these pieces in a way that lets us control the computer.
When we use SROP, we're telling the computer's operating system to make a certain change or take a certain action as soon as it receives a specific signal from the program we're running. This signal is called a "signal return," and it's like a secret code that the computer is waiting for.
When we send the signal return, the computer responds by following a specific set of instructions that we create in the program we're running. We carefully craft these instructions to make sure they tell the computer to do exactly what we want it to do.
SROP is often used by computer security researchers who want to see if they can hack into a computer's operating system. They try to use SROP to take control of a computer without being detected or stopped.
Overall, SROP is a very powerful technique that requires a lot of skill and knowledge to use correctly. But if used properly, it can help computer programmers and researchers uncover vulnerabilities in computer systems and make them more secure.
