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, since you must: 1) get machine code onto the stack, 2) set the return pointer to the start of this code, and 3) avoid corrupting other parts of the stack state.In this video, I demonstrate how to solve the Bomblab Phase 1 for Computer Systems. I assume that the student has already set up a VPN connection to a Linux ...4.1 Level 1 For Phase 1, you will not inject new code. Instead, your exploit string will redirect the program to execute an existing procedure.
