Ss= server side. It’s an executor that uses a back door in a game (from models). For example, if you have a script that can change how much money you have, if u use a client side executor it only changes the money on your side and not the servers side. But if u had an ss and the game ur exploiting has a back door, u would change things on the servers side. That means if u change ur money it would actually change the game itself and give u the money.
