Line +32 checks that sscanf read exactly 1 number, otherwise the bomb will explode. Line +59 is checking the return value of func4 against 610, so you need to figure out what number to feed func4 such that it will give 610 back.Attack Lab是ICS课程的第三个lab，顾名思义就是让我们想办法攻击一些程序，让其偏离原先的运行方式。 ... 前三个phase都是让程序运行我们写入的代码，所以我们要设置好运行的程序或者地址，然后让程序在ret时进入我们安排好的位置。 ...In this video, I demonstrate how to solve the Bomblab Phase 3 for Computer Systems.

What you are trying to do is overflow the stack with the exploit string and change the return address of getbuf function to the address of touch1 function. You are trying to call the function touch1. run ctarget executable in gdb and set a breakpoint at getbuf. b getbuf. Then disasemble the getbuf function. disas.Phase 2 involves injecting a small code and calling function touch2 while making it look like you passed the cookie as an argument to touch2 \n. If you look inside the ctarget dump and search for touch2, it looks something like this: \n
