Lab Walkthrough Video:


Doorman was deployed on a server to monitor the hosts in a network. The administrator of the servers had provided temporary sudo access to unprivileged users. One of the servers got compromised by an internal user. Analyze the recorded logs and answer the following questions:

  1. On the compromised host, the attacker had downloaded a script from a remote server using the curl utility. Provide the domain name of the server from which the script was downloaded.
  2. Upon execution, the downloaded script downloaded a package was downloaded that consisted of utilities necessary to capture user input. Provide the name of that package.
  3. Provide the complete path of the system utility used to record keystrokes.
  4. The directory containing the recorded keycodes was archived and uploaded to a remote server. Provide the IP address of the remote server to which the archive was uploaded.
  5. Provide the IP address of the compromised server.

Technical Support for this Lab:

There is a reason we provide unlimited lab time: you can take as much time as you need to solve a lab. However, we realize that sometimes hints might be necessary to keep you motivated!

We currently provide technical support limited to:

  • Giving hints for a lab exercise
  • In rare circumstances, if you have totally given up (NO!!!) then tell you how to solve it. This will be limited to sharing the solution video or lab report
  • A lab exercise fails to load or has errors in it

If you need technical support, please email  attackdefense@pentesteracademy.com  clearly mention the name and link of the lab exercise and other essential details. The more descriptive you are, the faster we can help you. We will get back to you within 24 hours or less.
