The Borg in Us All: Is Resistance Futile?

One of the main roles played by science fiction is to portray fundamental issues and questions that face humanity long before they actually become relevant to our daily lives. We cannot always be sure of where our reality ends, and fiction begins. Star Trek storylines including Borgs are a good example. In the storyline, Borgs are part organic, part artificial and created eons ago, yet they seem to presage the challenges in our contemporary personal reality and challenges in the Internet's cyberspace. more

Why Passive DNS Matters in Cybersecurity

Imagine a scenario. Your website analysis shows that your page has stopped receiving visitors, yet there are no complaints that your domain is unreachable. Strange, isn't it? You are certainly wondering: What's going on? Where are my customers? You see, what happened is that you are facing the consequences of the lack of domain name system (DNS) security. more

A Case for Regulating Social Media Platforms

There are some who see the regulation of social media platforms as an attack on the open internet and free speech and argue that the way to protect that is to let those platforms continue to self-regulate. While it is true that the open internet is the product of the same freedom to innovate that the platforms have sprung from, it is equally the product of the cooperative, multi-stakeholder organisations where common policy and norms are agreed. more

DNS Privacy at IETF 104

From time to time the IETF seriously grapples with its role with respect to technology relating to users' privacy. Should the IETF publish standard specifications of technologies that facilitate third-party eavesdropping on communications or should it refrain from working on such technologies? Should the IETF take further steps and publish standard specifications of technologies that directly impede various forms of third party eavesdropping on communications? more

Why More Registries Should Be Talking About DNS Security

I've been incredibly lucky in my time at Neustar to lead both the exceptional Registry and Security teams. While these divisions handle their own unique product and service offerings, it's clear that they have some obvious crossovers in their risks, opportunities and challenges. Having been closely involved in the strategy of both these teams, it strikes me that there is more we as Registry Operators and service providers can and should be doing to align the world of cybersecurity with that of domain names. more

Unexpected Effects of the 2018 Root Zone KSK Rollover

March 22, 2019, saw the completion of the final important step in the Key Signing Key (KSK) rollover - a process which began about a year and half ago. What may be less well known is that post rollover, and until just a couple days ago, Verisign was receiving a dramatically increasing number of root DNSKEY queries, to the tune of 75 times higher than previously observed, and accounting for ~7 percent of all transactions at the root servers we operate. more

A Dangerous, Norm-Destroying Attack

Kim Zetter has a new story out describing a very serious attack. In fact, the implications are about as bad as possible. The attack has been dubbed ShadowHammer by Kaspersky Lab, which discovered it. Briefly, some crew of attackers -- I suspect an intelligence agency; more on that below -- has managed to abuse ASUS' update channel and private signing key to distribute bogus patches. more

India’s Draft National E-Commerce Policy: A Bollywood Drama in Four Acts

India's recently published Draft National e-Commerce Policy, prepared by the Indian Commerce Ministry think-tank, can be read like the script of a four-act Bollywood drama... They were the dream couple: Princess India and Prince IT. She was full of cultural richness and diversity, with beauty, mystique and natural resources. She also a dark side. She harbored the world's largest number of impoverished people, with little infrastructure, and facing sparse economic prospects. more

A Short History of DNS Over HTTP (So Far)

The IETF is in the midst of a vigorous debate about DNS over HTTP or DNS over HTTPS, abbreviated as DoH. How did we get there, and where do we go from here? (This is somewhat simplified, but I think the essential chronology is right.) Javascript code running in a web browser can't do DNS lookups, other than with browser.dns.resolv() to fetch an A record, or implicitly by fetching a URL which looks up a DNS A or AAAA record for the domain in the URL. more

How to Track Online Malevolent Identities in the Act

Want to be a cybersleuth and track down hackers? It may sound ambitious considering that malevolent entities are extremely clever, and tracing them requires certain skills that may not be easy to build for the typical computer user. But then again, the best defense is offense. And learning the basics of sniffing out cybercriminals may not only be necessary nowadays, it has become essential for survival on the Web. So where can you begin? more
