I would never take a cruise but in other places with paid wifi that I did not want to pay for, IP-over-DNS tunneling worked well.
I would never take a cruise but in other places with paid wifi that I did not want to pay for, IP-over-DNS tunneling worked well.
Which services or apps do you advise for it?
Iodine is the go-to for IP-over-DNS tunneling: https://github.com/yarrick/iodine
Back in the Before Times when my wireless telephone didn't support tethering / hotspot iodine was very handy, albeit excruciatingly slow.
Very rarely did I find a network I couldn't tunnel out of. Virtually nobody thinks about DNS exfil.
(Did a gig one time where we did live-off-the-land exfil of base64 encoded data using CERTUTIL, CMD, PING, and tcpdump running on an off-site DNS server.)
