How about levels of exploit unsafe c code? Like this one
int main() { char excepted[] = "hackthis."; char actual[32]; printf("%p %p\n", excepted, actual); scanf("%s", actual); if (memcmp(actual, excepted, sizeof(excepted)) == 0) { printf("pass level\n"); } else { printf("wrong password\n"); } return 0; }
Although it’s platform and compiler dependent, the attack methods is valuable for many real case.
