I agree, it absolutely is interesting research, and I appreciate the detailed explanation that was published.
Although the proximity requirement severely limits the possible impact, it does make us think again about the security of our Wi-Fi networks, and as a result we may identify areas to improve, which is a benefit.
I agree with the industry response here. KRACK was the same thing. The author finds a vulnerability that is absolutely valid (no denying here), easy to exploit in a lab but very hard to exploit in practice. Back in the day, we did test our equipment for KRACK. We concluded that someone had to circumvent all our physical security barriers (challenging, but theoretically possible) to get close enough to an AP that would see sensitive stuff, had to know WHEN to do that, or at least plant a device that could easily be noticed, and they would still fail because we didn't have 802.11r enabled on those AP's.
Is it a concern? It depends on what you're doing. It is absolutely a concern if your corporation is handling ultra-sensitive information. However, you should also question your physical barriers in that case and whether you should use Wi-Fi at all for some aspects of your operation. Is it a concern for the vast majority of office workers or someone at home? Probably not; there would be easier ways to find a valid credit card number that don't involve the time and effort for a hacker to travel to your place where they could be discovered. There's no need to replace all your AP's with new hardware, although the Wi-Fi Alliance would love for you to do that.
Does this exploit warrant its own fancy name and domain name? As was the case for KRACK, I don't believe so. That should be reserved for vulnerabilities that have a severe impact AND are extremely trivial to exploit with no proximity requirements. If not, the fancy-name-vulns risk being deprived of their ability to get the attention that is required.
Oh, we can fulfill them. We'll resort to TLS inspection and force you to trust our CA on your device if you want to continue accessing our corporate network. And now we get to see (almost) everything again, like in the "good old days," not just your DNS queries.
Clear text DNS is the ultimate compromise, a gentleman's agreement if you want, that benefits everyone. We can see just enough to filter what we are required to by law on a best-effort basis, but we never see what you are actually doing thanks to the prevalence of TLS. DoH just broke that agreement.
It's a sad example of how a privacy solution like DoH will eventually result in less privacy, at least in some environments. And I'm not even considering how DoH will be the excuse for totalitarian regimes to up their surveillance antics.
I also appreciate the open nature of Reddit. No account is required if you just want to read, and you don't need to be first "approved" to most subreddits to be able to contribute. No "real-name" policies that often do more harm than good either.
While Facebook by default erects walls around content, Reddit by default promotes the free sharing and equal access to information, which resonates much more with the original promise and mission of the internet.
It's encouraging to see Reddit overtaking Facebook in popularity at a time when the freedoms of the internet are often under attack. Yes, Reddit has its flaws, but in the end, it is one of the best defenses that we have.
