Selected Executive Interviews

Most DNS traffic passes through just a few name servers

In this article about DNS Observatory, a new project supported by Farsight Security, Dr. Paul Vixie voices his concern about the growing consolidation of DNS servers. "The idea that we're going to ultimately end up with a dozen companies that have all our information and know everything about us because it just has become impractical to operate any service for ourselves because everything is so complicated now—that's crazy."


DNS hijacking grabs headlines, but it’s just the tip of the iceberg

DNS pioneer Paul Vixie contemplates missed opportunities for improving internet security and advocates for widespread use of DNSSEC, which he helped create, and which he believes would go a long way toward improving DNS security.


'The biggest, strangest problem I could find to study'

In this article, Dr. Vixie provides his take on a recent study on web traffic, which showed that only a small percentage of the traffic is benign. "On the internet, nothing that can be abused will not be," he says.

Business Insider

Internet pioneer Paul Vixie thinks we're giving up both privacy and speed thanks to the way we've configured our internet connections

In this interview, Dr. Vixie explains why public DNS servers run by Google and other vendors provide few benefits and are costing users both privacy and time. Here, he advocates organizations run their own local DNS servers.

The National Journal

New Lobby Against EU’s Domain-Name Privacy Rules Sparks Congressional Interest

In this piece, Dr. Vixie discusses the future of Whois and the possible success of advocacy groups working to pass legislation to enable security practitioners to have access to this data for years to come.

The Irish Times

Dr Paul Vixie: 'We are going to have our day of reckoning with Big Data'

Explaining his decision to offer real-time and historical passive DNS solutions, Dr. Vixie said, “We decided to invest and make a long, multi-year strategic investment in trying to create a system that would put back pressure on the real source of trouble, which is that these things [domains] are too cheap.”

The Times of London

'I created a firm to change the rules on cybersecurity'

In this interview, Dr. Vixie explains why he cofounded Farsight Security. “All war is a matter of economics. It continues until one side lacks the resources to continue. That’s the approach we take to cyber security — to make what online criminals are trying to do both difficult and expensive for them.”

Silicon Republic

DNS pioneer Paul Vixie on the evolution of the internet

Dr. Vixie urges people to take control in shaping an internet that is safer and more true to the original community-based mission a couple of decades ago. “We must not let it just be the big tech companies that decide humanity’s future. There are enough people with good intentions out there.”

Irish Examiner

Internet pioneer: Social media giants 'merely paying lip service' to changing behavior

In this interview, Dr. Vixie discusses why he believes social media giants are engaged in "surveillance capitalism" and are "merely paying lip service" to combating the rise of disinformation, data misuse, and online abuse. “They are merely paying lip service to it, delaying and deceiving and misdirecting as a way to continue growing revenue and their share price.” Podcast

Internet pioneer Dr Paul Vixie on pushing back against cyber crime

The DNS inventor talks about the past, present and future of security.


The Morris Worm Turns 30

Looking back 30 years when The Morris Worm hit, Dr. Vixie reflects, "[The Morris Worm] was a seminal event. It was the first time we realized a global, connected infrastructure was going to be globally vulnerable."

HelpNet Security

SIE Europe: Data sharing initiative to combat cybercrime launches

In this interview, Dr. Vixie discusses why he cofounded SIE Europe: “We founded SIE Europe to build a European-based community of Internet defenders who want to make the Internet safer for all users.


The risks associated with global Internationalized Domain Names

Dr. Vixie explains how global Internationalized Domain Names, or global IDNs, sparked the emergence of confusingly similar website addresses with nefarious goals -- and how organizations can combat them.


Paul Vixie wants to stop malicious domains before they're created

An interview with Dr. Vixie about the Farsight research report, "The Modality of Mortality in Domain Names: “Yes, we're seeing more blacklisting today. And I saw this coming -- again, I'm a bit of cynic. In 2010 at my previous company, a nonprofit DNS research and operations company, we invented a language for DNS blacklisting (DNSBL).”


'Short, Brutal Lives': Life Expectancy for Malicious Domains

An interview with Dr. Vixie about the Farsight research report, "The Modality of Mortality in Domain Names." “Most of them die young, and most of them die after living short, brutal lives," he says of newly created domains.”


This hard-to-spot online scam makes you think you’re getting free airline tickets

Dr. Vixie explains how IDN homographs are being used in phishing attacks against major airliners. “It is the perfect crime because once you have gathered someone’s real username and password, you can impersonate them on the airline’s website.”


The Uncertain Fate of WHOIS, & Other Matters of Internet Accountability

Dr. Vixie discusses the uncertain fate of WHOIS in the age of GDPR, the risks of domain name homographs, and other underpinnings of the Internet that are hard to trust and harder to fix.

BBC News

Why some computer viruses refuse to die

An interview with Dr. Vixie about his work on the Conficker Working Group and why Conficker is still around 10 years after its’ first discovery. "We got it from 11 million down to one million," said Dr Vixie. "That sounds like progress but one million is still a pretty big number."

Associated Press

Mystery: Who bought websites implying US senators 'for sale'

In this piece Dr. Vixie discusses the increase sale of U.S. Senator domain names using the .forsale domain extension and possible risks to the U.S. midterm election. “It’s no different from dot-sucks,” said Paul Vixie, a highly regarded computer scientist who helped design the system of Internet addresses current in use. “Social commentary has always thrived on the Internet, due to reach and cost issues.”

BBC News

Scammers abuse multilingual domain names

In this interview, Dr. Vixie discusses the Farsight research report on IDNs and the security risks these homographs pose to organizations. "Any lower-case letter can be represented by as many as 40 different variations."

IEEE Spectrum

Why Russia Is Building Its Own Internet

In this interview, Dr. Vixie explains why he doubts ICANN will remove .ru from the Internet. “That would be the biggest shockwave in the history of the Internet,” he says. “It would cause not just Russia but other countries to say, ‘We can’t trust ICANN.’”

Silicon Valley Business Journal

Internet pioneer on tech in 2018: 'Not a world I would've signed up for'

In this interview, Dr. Vixie reflects on the early days of the Internet and his contributions to the Domain Name System (DNS). “You're always going to get something you weren't expecting as one of the results of a rebellion and I don't like seeing the DNS used for crime, that's true.”


1 big thing: We built the internet to be insecure

Discussing why security was not top of mind when the Internet was first created, Dr. Vixie said, “No one ever thought someone would want to lie in the 'from' field of an email, or send email the recipient wouldn't want. And that made sense for a network of academics and military contractors, before anyone who could pay an internet service provider could get online.”


A View from Silicon Valley

In this interview, Dr. Vixie discusses why the cybersecurity M&A market is hot right now: “The M&A market is extraordinarily frothy,” says Paul Vixie. “[This market] is like bitcoin. If you think everyone else is excited about it, you invest in it.”

PBS NewsHour

Hackers are flooding the internet with more fake domain names. Here’s how you can protect yourself

Dr. Vixie shares Farsight research about the security risks posed by IDNs. “This problem got worse than we thought it could, faster than we thought it could,” said Paul Vixie, Chairman and CEO of Farsight Security and one of the developers of the Domain Name System that configures IP addresses into readable domain names.
