HackMyVM got founded around 2020 from a spanish man called sML.
It is quite community driven and offers various challenges online, as well as some downloadable virtual machine images to crack, exploit, jailbreak and explore.
It is noteworthy, that this might be the first site with jailbreaking a VM, so we introduced a new category "Docker".
In total, 363 challenges are available on the platform and i very welcome them!
