Congrats! We’ve now built a solid hacker lab. We could improve it by adding VPN access, creating a CTF scoreboard, and implementing a way for lab guests to control VMs without giving them free reign over the
phpVirtualBox web interface. But these would all be considered “stretch goals,” if we were crowd-funding this endeavor; the core of the system is complete as it stands, and the lab is ready to be populated by vulnerable targets!
