RaspberryPi/Reverse SSH Stunnel

We covered setting up a forward SSH tunnel over SSL using stunnel in the RaspberryPi/SSH Stunnel article, where the Raspberry Pi was the client and the command and control server was a laptop running Kali Linux.

Now we'll cover the extension of that scenario to our reverse SSH scenario: RaspberryPi/Reverse SSH

Basically, we'll be extending the Reverse SSH procedure to work over stunnel. This will give us a Raspberry Pi that will create a backdoor connection via SSH over SSL, on port 443, so it looks like standard SSL traffic and thus gets past firewalls and intrusion detection systems.
