Figure 1 summarizes the five phases of the lab. As can be seen, the first three involve code-injection (CI) attacks on CTARGET, while the last two involve return-oriented-programming (ROP) attacks on RTARGET. Note that the fifth phase is extra-credit. 4 Part I: Code-Injection Attacks For the first three phases, your exploit strings will ...This phase is so easy and it just helps you to get familiar with this lab. You can choose to use the command objdump or just use gdb to solve this lab. One way is to use the command objdump and then you get the corresponding source code of getbuf() and touch1() function:The purpose of the Attack Lab is to help students develop a detailed understanding of the stack discipline on x86-64 processors. It involves applying a total of five buffer overflow attacks on some executable files. There are three code injection attacks and two return-oriented programming attacks.

最开始试图用 Phase 4 的办法，一个个尝试可行的 mov 方案，后来发现可能性太多了，一个个搜起来太麻烦（如本题从 %rax 到 %rsi 就中间周转了 2 次，最差可能要试 8 ^ 2 = 64 种情况）；因为 pop 、mov 本身的字节指令有规律，完全可以在 rtarget 中将所有的 pop 、mov ...最开始试图用 Phase 4 的办法，一个个尝试可行的 mov 方案，后来发现可能性太多了，一个个搜起来太麻烦（如本题从 %rax 到 %rsi 就中间周转了 2 次，最差可能要试 8 ^ 2 = 64 种情况）；因为 pop 、mov 本身的字节指令有规律，完全可以在 rtarget 中将所有的 pop 、mov ...

Phase 1 \n. In phase 1 we are trying to overflow the stack with the exploit string and change the return address of getbuf function to the address of touch1 \n. First we run ctarget executable in gdb, we open the terminal and write \n. gdb ctarget \n. To inspect the code further we run a break on getbuf and run the code: \nFor this phase, we will be using the program rtarget instead of ctarget \n. This phase is the same as phase 2 except you are using different exploit method to call touch2 and pass your cookie. \n. In the pdf it tells you to find the instructions from the table and one of the instructions you will use involve popping rdi register off the stack, \nPhase 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
