For this phase, we will be using the program rtarget instead of ctarget . This phase is the same as phase 2 except you are using different exploit method to call touch2 and pass your cookie. . In the pdf it tells you to find the instructions from the table and one of the instructions you will use involve popping rdi register off the stack,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 \n. If you look inside the ctarget dump and search for touch2, it looks something like this: \nWe do not condone the use of any other form of attack to gain unauthorized access to any system resources. You will want to study Sections 3.10.3 and 3.10.4 of the CS:APP3e book as reference material for this lab. Instructions.

Cookie: 0x434b4b70. Type string:T make attack. As for study phase, it could be interesting to look at the cycle count curves. To do that, we can run make overview_attack. Example of curves, for the phase phase, with the private key to find: We would kill both processes on server and client side after the processing of 2^24 800-byte packets, as the study phase.Last step is to generate the raw eploit string using the hex2raw program. ./hex2raw < phase3.txt > raw-phase3.txt.
