About VulnHub
You download a machine and run it on your own computer in a tool such as VirtualBox or VMware, on an isolated network. Each machine is a self-contained puzzle with a goal set by its author.
You do not need an account to download. Note that the newest machine dates from July 2022, so the catalog is no longer growing. It suits learners comfortable setting up a home lab.
