Second dns2tcp, although there's also Heyoka http://heyoka.sourceforge.net/, Netcross http://www.primianotucci.com/os/netcross-ip-over-dns-tunneli..., and a rather interesting presentation from Defcon a few years back that showed a more detailed and realistic scenario of using DNS tunneling to punch through a firewall and retrieve database records. I can't locate it right now, but I'll take a look if anyone's interested.

Yes please, I'd be super interested in watching that talk!

Haha, fifteen minutes of Googling later, here you go: Slides: https://www.defcon.org/images/defcon-16/dc16-presentations/d... Talk: https://www.youtube.com/watch?v=IkXG14MA3M4

I kept missing the search term. It was "data exfiltration" not "dns tunneling."
