The phase 1 for my attack lab goes something like this: Ctarget goes through getbuf (), in which I should create a buffer for the function to jump directly to the function touch1 () instead of the function test (). From my understanding, I should find the buffer size and create a padding for it, then after the padding input the little endian ...The move sets up a possible showdown between the international court and Israel with its biggest ally, the United States.

Instead, your exploit string will redinect the program to execute an existing procedure. Function getbut is called within CTARGET by a function test having the following C code: When getbuf executes its return statement (line 5 of getbuf), the program ...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 ...

3-Attack Lab. 1. phase 1. 利用栈溢出覆盖getbuf函数的返回地址. 答案 前五行是正常写入buf的数据，第六行是touch1的地址0x4017c0,用于覆盖getbuf ()函数的正常返回地址。. 注意写入的数据不能是0x0a，这个数字表述"\n",Get ()函数遇到0xa会终止。. 栈大小.For 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.

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. If you look inside the rtarget dump and search for touch2, it looks something like this: 000000000040178c <touch2>: 40178c:48 83 ec 08 sub $0x8,%rsp.
