  1. Challenge

    Getting Started in the Lab Environment

    Here are the initial instructions and explanation of the lab environment. Read this while your environment is busy creating itself from nothing. Yes, this violates physics; we know. How fun!

  2. Challenge

    Leveraging Weak Credentials to Gain Access

    You will explore the attack surface of an IOT device that is running a weakly configured web application. You will learn how to detect a running application on an IOT device by scanning for open ports on the device.

  3. Challenge

    Brute Force Telnet Protocol

    You will use the Nmap scanning tool to run a script that is related to the telnet protocol and attempt to brute force the password for the telnet user and you will observe the attempt in Wireshark and you will use a utility of Nmap and perform the same test. Finally, you will use Metasploit to perform a brute force attack against the telnet user as well.
