    Now, technical plenary at #IETF105, on #privacy. Live at https://www.youtube.com/watch?v=VT4-xIZ-tNs

    Arvind Narayanan and Steve Bellovin on stage.

    Ted Hardie introducing Bellovin: "He was on Usenet. You may have heard of that."

    Narayanan talks (very fast) about privacy measurements.

    Some slides titles at #IETF105 are surprising:

    "Privacy-conscious monitoring"

    RDAP ( RFC 7480 - 7484) will replace the old WHOIS protocol this August for some gTLD/nTLD registries.

    I found the tools from https://openrdp.org useful:

    Working here on xBSD, macOS and Linux. Probably also work on Windows (haven't tested)

    Performances of #DoH (#DNS over HTTPS) and #DoT (DNS over TLS). Does it have consequences on user experience?

    DoH (and DoT) can be, in some cases, *faster* than traditional DNS, thanks to the use of TCP.

    Oblivious DNS, a protocol for protecting privacy on the #DNS

    Existing privacy techniques do not protect against the resolver. The resolver stills sees everything.

    Solution: encrypted DNS-over-DNS tunnel between the client and the Oblivious DNS server (which pretends to be auth. but is actually the real resolver). It will see the query but not the user, and the default resolver wll see the user but not the query.

    Implemented in Go. Good performances.

    7 % AS do it world-wide (17 % in China). So, it is common. Funnily, very often, responses are NOT tampered with.

    Solutions: #DNSSEC validation on the client, encrypted DNS

    #DNS interception: who is answering my queries?

    Internet access providers, governments, antivirus software and of course malware intercept DNS requests and send false replies.

    How to measure its prevalence? Check at the auth. server if there is a request and where does it come from. Careful: interception policy may depend on many things (qtype, TLD in the qname, DNS resolver, etc).

    Woah, #PaloAlto: Silently fixed a pre-authentication remote code execution vulnerability in their VPN portal a year ago, and did not notify their customer. Anyone who didn't update their PanOS during the past year is still vulnerable (CVE-2019-1579).
