Laboratory Exercise: Hands-on with Password Auditing and Buffer Overflows
This individual laboratory exercise will familiarize you with the Virginia Cyber Range and provide some hands-on experience with password cracking and buffer overflows.
This exercise makes use of resources provided in the Virginia Cyber Range. It is a single Ubuntu virtual machine with artifacts necessary (hashed passwords and executable files with buffer overflow vulnerabilities).
This lab exercise requires an account on The Range. To sign up for an account on The Range, please visit our Sign-Up page. Your students will also require an account on the Virginia Cyber Range; this will be explained in the setup of your course.
For Task 2 (Basic Buffer Overflow), this lab exercise comes with a video file called Buffer_oflow_walkthru.mp4 that is very helpful in describing to students the process for exploiting buffer overflow vulnerabilities. You may access and download it here: buffer_oflow_walkthru_v2.mp4
