# Attack Lab
## Introduction
Lab 3 for CSCI 2400 @ CU Boulder - Computer Systems
> This assignment involves generating a total of five attacks on two programs having different security vulnerabilities. The directions for this lab are detailed but not difficult to follow.
Again, I like using objdump to disassemble the code.
`objdump -d ctarget > dis.txt`
## Phase 1
From the instructions, we know that our task is to get `CTARGET` to execute the code for `touch1` when `getbuf` executes its return statement, rather than returning to `test`
