Phishing: the Worst of Times in the DNS

The Anti-Phishing Working Group has released its latest Global Phishing Survey, written by myself and Rod Rasmussen. This report comprehensively examines a large data set of more than 250,000 confirmed phishing attacks detected in 2015 and 2016. By analyzing this cybercrime activity, we have learned more about what phishers have been doing, and how they have done it. Unfortunately, there's more phishing than ever, and phishers are registering more domain names than ever. more

DNS MythBusters - Straightening Out Common Misconceptions

Over the last couple of years, the networking industry has grown aware of the various security issues that could potentially have a huge impact on their operations. One of the topics that has raised in appeal is DNS security. Considering that much of the publicity around DNS is made by vendors trying to differentiate their solutions, there are many misconceptions out there that guide people into making poor investment in their infrastructure. more

When Businesses Go Dark: A DDoS Survey

In February 2012, Neustar surveyed IT professionals across North America to better understand their DDoS experiences. Most were network services managers, senior systems engineers, systems administrators and directors of IT operations. In all, 1,000 people from 26 different industries shared responses about attacks, defenses, ongoing concerns, risks and financial losses. more

Internet Root Servers Hit with Unusual DNS Amplification Attack

On Nov. 30 and Dec. 1, several of the Internet Domain Name System's root name servers received high rate of suspicious queries, reaching as high as 5 million queries per second, according to a report released by the Root Server System Advisory Council. The incident has been categorized as a unique type of DNS amplification attack. more

Three Years With ICANN

I joined the ICANN board during the December 2004 ICANN meeting in Cape Town. I served for a three year term and stepped down at this last meeting in Los Angeles and didn't run for another term... Before joining ICANN, I thought that ICANN was the only part of the Internet that wasn't really working. I knew that there must be a better way to do what ICANN does, but I couldn't be bothered to figure it out. I'd agree with people who said things like, "it should just be distributed" or "it should just be first come first serve" or "we should just get rid of it." People from ICANN would say, "it's more complicated than that" or "at this point that would be impossible." After being part of the process for three years, I find myself saying those same things... 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

I Don’t Need a Signature to Know It’s Going to Be Bad…

There was a period of time not long ago in which signature-based threat detection was cutting-edge. Antivirus, intrusion detection systems (IDS), data leakage prevention (DLP), content filtering and even anomaly detection systems (ADS) all continue to rely heavily upon static signatures. In recent years vendors have shied away from discussing their dependence on such signatures -- instead extolling supplemental "non-signature-based" detection technologies. more

New TLD Applicants: Read This Before Selecting a Registry Provider

As each day passes, I spend more time immersing myself with prospective clients who are weighing up our offering over those of alternative providers. The more I become entrenched in this competitive process, the more it becomes increasingly clear that many of the competing RSPs pitching their wares to hopeful applicants are misleading them by hiding critically important information in fine print disclaimers or feeding them rubbish in order to whittle down the competition. Competition is a great thing; it just needs to be on the same playing field. Make sure you are comparing apples with apples. more

Why Most People Haven’t Heard of the DNS Root Server System

At the ICANN 81 meeting in Istanbul on 10 November 2024, I gave a presentation about the DNS Root Server System, in an effort to increase understanding of the Root Server System (RSS) and Root Server Operators (RSOs). The talk was intended for the members of the ICANN Governmental Advisory Committee (GAC), but much of this explanation may be of interest to general audiences. more

I, the Domain Name Tasting Victim

I have recently been a "victim" of the domain name tasting "scam". A domain name (.COM) which is related to me personally (and which was owned by someone else previously) expired and as I knew from Whois (which is another debate on its own) that the expiry date was coming up, I kept a watch on when it would become available so I could register it. To cut a long story short, it took me nearly 6 weeks to get the domain. Each time the domain dropped off the 5 day grace period (it is not really something that would generate ad revenue), it would be picked up by a different registrant... more

Background on .EU the Upcoming European Identity

Progress is being made towards launching a .eu top-level domain for European individuals, business and organisations.

On 22 May 2003, the European Commission announced its decision to designate the European Registry for Internet Domains (EURID) as the Registry for the new top-level domain (TLD) .eu. EURID is made up of three founder members ? the registry operators for the country code top-level domains (ccTLDs) .be (Belgium), .it (Italy) and .se (Sweden). The Commission?s decision follows a call for expressions of interest published last September and an evaluation by independent experts of the seven applications received. more

DNS Security Flaw Secret Leaked Prior to Set Date: Patch DNS as Fast as Possible

In what seems to have started with a blog post by reverse engineer Halvar Flake, and subsequent blog postings from other experts in the know, the details of the recently announced DNS vulnerability was quite likely made public today. The DNS flaw was found earlier this year by security researcher Dan Kaminsky and earlier this month announced publicly along with various tools and patches provided by numerous vendors... more

More Mysterious DNS Root Query Traffic from a Large Cloud/DNS Operator

With so much traffic on the global internet day after day, it's not always easy to spot the occasional irregularity. After all, there are numerous layers of complexity that go into the serving of webpages, with multiple companies, agencies and organizations each playing a role. That's why when something does catch our attention, it's important that the various entities work together to explore the cause and, more importantly... more

US Government Waves the Caution Flag at ICANN

This month, ICANN is driving hard to get two of its horses to the finish line. The first is barely a year old - it's the first formal review of ICANN's accountability and transparency. The second horse is going on 4 years old: ICANN's plan to introduce hundreds of new top-level domains (TLDs) for the Internet. Just as these horses have entered the home stretch, one of the racecourse officials is vigorously waving the yellow caution flag. And ICANN would do well to pull back on the reins. more
