Bypassing conditional statements.

Right. I want to learn how you could jump a conditional statement in a compiled exe. My first thought process leads me to this approach :

• Reverse engineer and find the memory address of the instruction we want to jump to

• Create a DLL injection program that automatically injects into the required exe

• Write the DLL code that will be injected and provide the instructions for the jump

Let's begin by writing the C code that we will be trying to bypass.

#include "Windows.h"
#include "stdio.h"

int main(int argc, char** argv) {
	char* key;
	if ( argc > 1 ) {
		key = argv[1];
		if ( strcmp(key, "123456789") == 0 ) {
			printf("You have entered the proper key!\n");
		} else {
			printf("You have entered the wrong key!\n");
		}
	} else {
		printf("You have not entered the key!\n");
			
	}

	system("pause");

	return EXIT_FAILURE;
};
