Very interesting comments over all. Thanks for adding to the articles.
At a conference in New Orleans this January I found that the hotel wifi let me change the DNS resolvers, but hijacked port 53 and spoofed the replies. Following previous conversations I’ve had with Stéphane Bortzmeyer, I tested and was able to receive responses from non-existent resolvers. BoAs with many hotel situations, I couldn’t get reasonable service with the full VPN, and the split-VPN worked fine – except for the fact that they were jacking my DNS. I find this behavior extraordinarily unethical and easily able to fool most people who might think they are in their private network. This seemed identical to the reporting in the July 2018 paper: “Who is Answering my DNS Queries” , though most of their research was done in China. https://www.usenix.org/conference/usenixsecurity18/presentation/liu-baojun
