T = 78464 Previously, I tried to detect a hidden process and then solved it with the method of brute force enumeration. But the hook swapcontext didn't see complete code. So I collected some useful modules on the Internet and integrated them to implement support. xp3, xp2 should be supported even if it is not tested. Complete project code Difficulty: there are still some details about obtaining the swapcontext ad

locations are typically on the stack, but may also be in registers; this is specified by calling conventions. Program Execution jumps to the address of the called function. Inside the function, registers ESI, EDI, EBX, and EBP are saved on the stack. The part of code that performs these operations is calledFunction PROLOGAnd usually is generated by the compiler. The function-specific code is executed, and the return value is placed into the eax re
