Some time ago, I found a site that provided different variants of VMs you could download which contained exploits you could utilize to pwn the machines. There were also walkthroughs and guides available to teach you how to break in.
Unfortunately I can no longer find the site, and my Google fu has failed me.
Unlike Hack the Box, no signup was necessary, you could just download the VM and get started.
Does anyone here know of any good alternatives they'd like to recommend?
There is [vulnhub](https://www.vulnhub.com/). There was another one that started with an “e” (it had Linux and code challenges too (e.g. here is the C code, exploit privilege escalation)). I remember a few years ago the site went down and a mirror was stood up under a different domain. Don’t have those links unfortunately.
