7MS #586: DIY Pentest Dropbox Tips – Part 8

Today, sadly, might be the last episode of DIY pentest dropbox tips for a while because I found (well, ChatGPT did actually) the missing link to 100% automate a Kali Linux install! Check episode #449 for more info on building your Kali preseed file, but essentially the last line in my file runs a kali.sh script to download/install all the pentest tools I want. The "missing link" part is I figured out how to get Kali to reboot and then run a script one time to complete all the post-install stuff. So at the bottom of my kali.sh is this:

sudo wget https://somesite/kali-docker.sh -O /opt/kali-docker.sh sudo chmod +x /opt/kali-docker.sh sudo touch /flag sudo wget https://somesite/docker.service -O /etc/systemd/system/mydocker.service sudo systemctl daemon-reload sudo systemctl enable mydocker.service

The contents of docker.service are:

[Unit] Description=Docker install [Service] Type=simple ExecStart=/opt/kali-docker.sh [Install] WantedBy=multi-user.target

The beginning and end snippets of kali-docker.sh are:

#!/bin/bash flag_file="/flag" if [ -e "$flag_file" ]; then # get bbot sudo docker run -it blacklanternsecurity/bbot:stable --help # Do a bunch of other install things...

So essentially the work flow is: kali.sh runs, downloads and installs kali-docker.sh, and also installs a service that runs kali-docker.sh on each reboot. But when kali-docker.sh runs, it checks for the presence of a file called /flag. If /flag exists, all the post-install commands will run. If it does not exist, those commands won't run. Simple, yet genius I think!
