Web shell is a Web script that is placed on an openly accessible Web server to allow an adversary to use the Web server as a gateway into a network.
In this lab, we are given SSH access on the target machine. The flag is not on
machine yet and will only be available after "wait" file present in user
home directory is deleted. However, the deletion of this file will change the user password and restart SSH. Hence, to retrieve the flag, we have to maintain access on the target system.
Initial SSH Credentials
- Maintain access on target machine by hosting a web shell.
- Retrieve flag from target machine.
- WebShell (https://attack.mitre.org/techniques/T1100/)
- This lab is dedicated to you! No other users are on this network :)
- Once you start the lab, you will have access to a root terminal of a Kali 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

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.
For adminitrative queries, billing, enterprise accounts etc. please email firstname.lastname@example.org
