What it does
VulnHub lists downloadable virtual-machine challenges with descriptions, difficulty information and platform notes for security practice.
The machine description matters before choosing a VulnHub challenge. Look for its intended difficulty, virtualization notes and any stated objectives so that the environment fits your experience and setup. The catalogue is practice material rather than a sequenced course, so learners need to select and arrange suitable challenges themselves.
Downloaded machines run in your own virtualisation setup. Check each entry’s hypervisor and networking notes, since a VirtualBox-tested image may behave differently in VMware.
