Lab Walkthrough Video:


Kibana and Elasticsearch setup is provided with SSH logs of multiple server machines. You have to analyze the logs using Kibana interface and answer the following questions:

  1. How many machines were attacking the SSH servers?
  2. Which machine made the most SSH login attempts?
  3. How many servers running SSH service were attacked?
  4. What is the IP address of the attacker machine that made the maximum login attempts on the most attacked SSH server?
  5. How many SSH authentication modes were used by the attacking machines to break into the servers?
  6. What was the IP address of the attacker machine which used public key authentication to break into the SSH servers?
  7. SSH service was running on which port on all the servers? Provide port number.
  8. What is the name of the user account that got compromised on the SSH servers?
  9. At what time the maximum number of logs were pushed into elasticsearch? Provide the time in HH:MM:SS format.
  10. What is the IP address of the SSH server that got compromised first?

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. 

For adminitrative queries, billing, enterprise accounts etc. please email feedback@binarysecuritysolutions.com
