Cleaning up the Black Hat Bash environment, this may take a few moments...

OK: lab environment has been destroyed.

Listing 3-1

Lab cleanup command output

After running the command, you should receive a confirmation that the lab

environment has been destroyed.

Rebuilding

When we execute a rebuild, the lab will first shut down all running containers,

delete volumes, and remove all container images before running a new

deployment. To execute the rebuild, run the following command:

$ ./run.sh rebuild

If you rebuild the lab, you’ll lose any data you saved inside of your containers.

Rebuilding is useful when something goes wrong during installation. Maybe, half-

way through it, you lost your network connection, and it reported a failed state.

The rebuild command allows you to wipe and install it from scratch.

Accessing Individual Lab Machines

As you progress through the book, you’ll compromise the machines in the lab

environment. However, it often takes multiple attempts to obtain full access to a

machine. Sometimes, you may need to troubleshoot an issue or reproduce a post-

compromise activity, and you won’t want to repeat the steps you performed to

obtain access.

To gain shell access to any individual lab machine, you can run the following

Docker command:

$ docker exec -it MACHINE-NAME bash

MACHINE-NAME represents the name of a lab machine, such as p-web-01 or

p-jumpstation-01 (or any other machine from Table 3-1 that starts with p- or c-).

The Docker command will drop you into a bash shell, at which point you can

execute any command you like. To exit, simply enter exit in the prompt or close

the terminal session’s window.

We highly recommend you compromise the machines as intended before

taking these convenient shortcuts, however.

Installing Additional Hacking Tools

Most of the tools we’ll use in this book will come pre-installed in Kali, and

we’ll introduce them upon first use. However, we’ll need several tools that aren’t

installed by default, so let’s install them here. First, create a new directory in

which to place your tools:

$ cd ~
