Verisign Outreach Program Remediates Billions of Name Collision Queries

A name collision occurs when a user attempts to resolve a domain in one namespace, but it unexpectedly resolves in a different namespace. Name collision issues in the public global Domain Name System (DNS) cause billions of unnecessary and potentially unsafe DNS queries every day. A targeted outreach program that Verisign started in March 2020 has remediated one billion queries per day to the A and J root name servers, via 46 collision strings. more

Newer Cryptographic Advances for the Domain Name System: NSEC5 and Tokenized Queries

In my last post, I looked at what happens when a DNS query renders a "negative" response -- i.e., when a domain name doesn't exist. I then examined two cryptographic approaches to handling negative responses: NSEC and NSEC3. In this post, I will examine a third approach, NSEC5, and a related concept that protects client information, tokenized queries. The concepts I discuss below are topics we've studied in our long-term research program as we evaluate new technologies. more

Brand Protection Beyond the “Whack-a-Mole” Approach

I recently shared at a conference how a seasoned brand and fraud expert from one of the world's largest global financial institutions lamented a major attack where multiple fraudulent websites would pop up every single day. All attacks were launched from the same registrar and web hosting company, and no matter how much they reached out to these providers, they received the same reply: "we will pass on your request to the registrant or site owner," and then nothing happened. more

Cryptographic Tools for Non-Existence in the Domain Name System: NSEC and NSEC3

In my previous post, I described the first broad scale deployment of cryptography in the DNS, known as the Domain Name System Security Extensions (DNSSEC). I described how a name server can enable a requester to validate the correctness of a "positive" response to a query -- when a queried domain name exists -- by adding a digital signature to the DNS response returned. more

The Domain Name System: A Cryptographer’s Perspective

As one of the earliest protocols in the internet, the DNS emerged in an era in which today's global network was still an experiment. Security was not a primary consideration then, and the design of the DNS, like other parts of the internet of the day, did not have cryptography built in. Today, cryptography is part of almost every protocol, including the DNS. And from a cryptographer's perspective, as I described in my talk at last year's International Cryptographic Module Conference (ICMC20), there's so much more to the story than just encryption. more

Exploring the Meanings of “Right” and “Legitimate Interest” (UDRP Proceedings)

For complainant, the second leg in determining cybersquatting under the Uniform Domain Name Dispute Resolution Policy (UDRP) is evidence respondent lacks both rights and legitimate interests in the challenged domain name (Paragraph 4(a)(ii)). I underscore "both" because proving one but not the other is not good enough. This seems obvious, so why suggest there is something to explore about "rights" and "legitimate interests" if their meanings hardly need explication? more

2020 Domain Name Year in Review

2020 - a year like no other. The impact of COVID on the domain name industry was felt far and wide as ICANN meetings were held virtually, travel was cancelled, TLD launches were delayed, the topic of domain name abuse was front and center, and we all tried to navigate a "new" normal. Unlike many sectors, the domain name industry was fortunate and, in many ways, survived 2020 unscathed. Much of our industry was able to continue working from home after an initial period of adjustment. more

Donuts Completes the Acquisition of Afilias

Donuts stated today that it has completed the acquisition of Afilias announced on November 19. Donuts' CEO Akram Atallah says the company is now ready to begin the integration plan promising minimal disruptions to customers. more

The Government of Niue Launches Proceedings With ICANN to Reclaim Its .nu Top-Level Domain

The Government of Niue, a small island 2,400 kilometers northeast of New Zealand, launched proceedings today demanding a "redelegation" of its country code top-level domain, .nu, from the Internet Corporation for Assigned Names and Numbers (ICANN). more

A Balanced DNS Information Protection Strategy: Minimize at Root, TLD; Encrypt When Needed Elsewhere

Over the past several years, questions about how to protect information exchanged in the DNS have come to the forefront. One of these questions was posed first to DNS resolver operators in the middle of the last decade, and is now being brought to authoritative name server operators: "to encrypt or not to encrypt?" It's a question that Verisign has been considering for some time as part of our commitment to security, stability and resiliency of our DNS operations and the surrounding DNS ecosystem. more

WIPO Arbitration and Mediation Center Registers Its 50,000th “Cybersquatting” Case

The WIPO Arbitration and Mediation Center on Monday announced it had registered its 50,000th "cybersquatting" case. The 50,000th case just received by WIPO coincides with the organization's 20th anniversary on November 20, 2020. more

Holiday Shoppers Beware: Tips on Protecting Brand Owners and Consumers from Domain Security Threats

With the COVID-19 pandemic persisting, online shopping will be the preferred method for the 2020 holiday shopping season. While staying home to shop is the safest option right now, it means consumers are more vulnerable to online fraud, counterfeits, and cyber crime. Increased online activity provides opportunities for unscrupulous infringers to abuse trusted brand names to drive visitors to their own fraudulent content. more

Authenticated Resolution and Adaptive Resolution: Security and Navigational Enhancements to the DNS

The Domain Name System (DNS) has become the fundamental building block for navigating from names to resources on the internet. DNS has been employed continuously ever since its introduction in 1983, by essentially every internet-connected application and device that wants to interact online. Emerging from an era where interconnection rather than information security was the primary motivation, DNS has gradually improved its security features. more

Donuts to Acquire Afilias

Donuts and Afilias announced today that Donuts is acquiring Afilias in a deal that is expected to close in December 2020 for an undisclosed amount. The combined entities will support over 25 million domain names spanning well over 400 TLDs. The deal will not include certain Afilias businesses, such as the mobile software and registrar businesses, which will remain with Afilias' original group of investors. more

Speculating in Domain Names: Pricing War(e)s

Speculation in one form of another has an ancient and honorable history. It not only creates entrepreneurial activity but fuels markets for selling wares and offering services, but also generates competition for consumers and wars over loyalty. The commercialization of the Internet in the 1990s, which extended market activity into virtual (cyber) space, has many of the virtues of the actual but also its vices: cheating and fraud, and other skullduggery. more
