If you look inside the ctarget dump and search for touch2, it looks something like this: \n22. Phase 1 : First we need to disas ctarget to assembly language file to see what it is doing inside. Because our exploiting technique needs to go through the getbuf function, we then search in the getbuf function. We can see that the command sub 0x28 %rsp indicates that the buffer is 40bytes long, so we must input the 40 bytes (in hexa of ...Step 1. We enter gdb, set a breakpoint at the phase 1. Then we take a look at the assembly code above, we see one register eax and an address 0x402400. Enter a random string and then we stop at the phase 1 position, then we try printing out the information around 0x402400.
