Your solutions have been very helpful, but we are having a lot of trouble with phase3. Is the rsp+0x28 increment standard for all attack labs?A lab that involves 5 phases of buffer overflow attacks. The first three deal with Code injection attacks and the last two phases deal with return operated attacks. Solutions are described below: Phase 1: Phase one is a simple solution approach.With this form of attack, you can get the program to do almost anything. The code you place on the stack is called the exploit code. This style of attack is tricky, though, because you must get machine code onto the stack and set the return pointer to the start of this code. For level 1, you will need to run your exploit within gdb for it to ...Attack Lab Phase 3 RSP: 0x5566fda0 Buffer: 0x28 (40 Decimal) Cookie: 0x769227bbf Phase 3 also involves a code injection attack, but passing a string as argument.
