Metasploitable is a virtual machine running Linux that aspiring hackers can use to break into and practice security.
As expected, this virtual machine is riddled with outdated software, services with vulnerabilities, and default passwords. It’s up to the end user learner to find how many ways they can break in.
I have found a few on my own. The first way I found through the Hacker Loi Youtube channel and it was the ProFTPvs backdoor. There are more ways and this VM is just like a giant puzzle box.
Nessus can make vulnerability much easier but the pros out there can just use Nmap to determine where the holes are.
If you’re an aspiring hacker and need practice definitely give Metasploitable a try. It is FREE and legal. Caution, do not use this on an open or untrusted network.
