Attack lab phase 1

Last step is to generate the raw eploit string using the hex2raw program. ./hex2raw < phase3.txt > raw-phase3.txt. Finally, you run the raw file. ./ctarget < raw-phase3.txt.

Attack Lab [Updated 1/11/16] (README, Writeup, Release Notes, Self-Study Handout) Note: This is the 64-bit successor to the 32-bit Buffer Lab. Students are given a pair of unique custom-generated x86-64 binary executables, called targets, that have buffer overflow bugs. One target is vulnerable to code injection attacks.Figure 1 summarizes the five phases of the lab.
