in this step, you'll create a "secret" user named sysd$.$ Anyone examining $/$etc$/$passwd will assume that this is a service account, but in fact, you'll be using it to reconnect to the target machine for further exploitation.

Create a sysd user.

Give your user a password $($make sure you remember it$).$

Give your user a system UID $($any UID below $1000).$

Give your user a GID equal to this UID.

Give your user full sudo access without a password.

Minimize exposure by ensuring that your secret user does not have a home folder.

Test that your sysd user can execute commands with sudo access without a password before moving on$.$

Try running sudo $-$l to test. If the terminal does not prompt you for a password, it was a success. Attempt any other commands that require elevated privileges and mark them in your Submission File.
