The full name of JOP is Jump-oriented programming, and attacks are similar to ROP attacks. It also exploits existing code snippets in binary executables for attacks. ROP uses ret instructions to change the control flow of the program, while JOP attacks use indirect jump and indirect call instructions (indirect call instructions) to change the control flow of the program. When a program executes an indirect jump or an indirect call, The program will obtain the destination addresses of its jumps from the specified registers. Because these jump destination addresses are stored in the registers and the attacker can modify the contents of the registers by modifying the contents of the stack, this allows the destination addresses of indirect jumps and indirect calls in the program to be attacked by the attacker.Allows an object to change its behavior when its internal state changes.
