A protected private Docker registry is deployed behind Nginx in the reverse-proxy configuration. The Nginx is in the same network as your Kali machine, but the registry is not directly reachable from your machine. Also, the Nginx proxy is protected with a popular authentication mechanism. There are some docker images present in the registry, one of which contains the flag.
Objective: Interact with the private Docker registry, analyze the images and retrieve the flag!
- This lab is dedicated to you! No other users are on this network :)
- Once you start the lab, you will have access to a Kali terminal instance.
- Your Kali has an interface with IP address 192.X.Y.Z. Run "ip addr" to know the values of X and Y.
- The target server should be located at the IP address 192.X.Y.3.
- Do not attack the gateway located at IP address 192.X.Y.1
- Username is bob and password wordlist to use is /root/wordlists/100-common-passwords.txt

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 email@example.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.
