You think linux doesn’t have a firewall? I’m fairly certain every distribution has one installed and enabled by default.

The real reason linux worked so well in this situation was the local admin rights that came from being a rogue, unmanaged device on the network. I’m sure they could have made windows work if all the group policies weren’t being enforced.

Even if you wrote the code yourself you can come back to it a while later and have a wtf moment ¯\_(ツ)_/¯
