What can we learn from a longitudinal analysis of phishing attacks observed at three #ccTLDs registries that manage more than 8M active domains? @gio_windwijzer and the @SIDNlabs team share the details: blog.apnic.net/2024/09/25/cct…

🔬💻Our new anti-phishing security study, a collaboration of @SIDN, @dot_ie, @DNSBelgium, @tudelft, @KU_Leuven, U. Twente & @UGrenobleAlpes, provides new insights on fighting 🎣🇳🇱🇮🇪🇧🇪 📄gsmaragd.github.io/publications/C… @TheOfficialACM #CCS2024 @EU_Commission #SafeHorizon @CyberSecTUDelft

How does the NTP Pool map clients to NTP servers and how can it be improved? @gio_windwijzer and fellow @sidnlabs investigate: blog.apnic.net/2024/03/15/ntp…

Today on the blog, @gio_windwijzer measures the structure of e-gov domain names: blog.apnic.net/2023/08/15/e-g… Based on research by Giovane Moura, @RaffySommy, Mattijs Jonker, and Jeroen van der Ham

Besides Google Public DNS supporting EDE and case randomization, they also support NSID (wich is great for troubleshooting anycast):

.@sidnlabs publiceerde onlangs een studie waarin de veerkracht en redundantie van digitale overheidsdomeinen in 4 landen worden vergeleken: Nederland, Zweden, Zwitserland en de Verenigde Staten. Er is ruimte voor verbetering. sidnlabs.nl/nieuws-en-blog…

How resilient are government domains? As e-governance initiatives rise, the reachability and redundancy of government domains become increasingly important. Giovane Moura (@gio_windwijzer) examines the #DNS configurations of e-gov domains on #RIPELabs: labs.ripe.net/author/giovane…

Feeling so old, when a young student talks to you and says “you wrote that paper about the root servers” FIFTEEN YEARS AGO #DNS #RIPE86

Will be presenting at #RIPE86 our work on measuring e-gov DNS deployments, part of the @ncsc_nl DINO project. 16:30 CEST / 14:30 UTC ripe86.ripe.net/live/main/ @SIDN @sidnlabs @CyberSecTUDelft @UTwente @ncsc_nl @RaffySommy @ripemeeting

Exciting moment at #RIPE86: Back in 2008, when I was an MSc student, a notorious BGP hijack incident targeted YouTube. Fast forward 15 years to the current #RIPE86 plenary session: A Google engineer, (W. Kumari) who was on call during that incident, shared his firsthand account.

Press release on a research we did for the @ncsc_nl evaluating the #DNS infrastructure of the Dutch gov. domain names. (@sidnlabs and @UTwente joint research) Peer-reviewed paper presented #CSNM2022, to be also presented at @ripemeeting in May. sidnlabs.nl/en/news-and-bl…

Top-notch. Admirable work.
