The Closing Window: A Historical Analysis of Domain Tasting

I wrote this history and analysis of domain tasting for the ICANN Business Constituency membership. It's by no means perfect but I thought I'd share it with those who would like a bit more color on the subject. "Present day 'Domain Tasting' has its roots in 2001 and 2002 when a small group of ambitious domain registrants persuaded two registrars to allow them to register large blocks of domain names for the purpose of establishing which names garnered type-in traffic..." more

Homeland Security Department Was Warned About DNSSEC Key Ownership and Trust Issues

The Internet Governance Project has unearthed a consultancy report to the U.S. Department of Homeland Security (DHS) that makes it clear that the issue of root signing and DNSSEC key management has been recognized as a political issue within the US government for long time. more

DNSSEC: Once More, With Feeling!

After looking at the state of DNSSEC in some detail a little over a year ago in 2006, I've been intending to come back to DNSSEC to see if anything has changed, for better or worse, in the intervening period... To recap, DNSSEC is an approach to adding some "security" into the DNS. The underlying motivation here is that the DNS represents a rather obvious gaping hole in the overall security picture of the Internet, although it is by no means the only rather significant vulnerability in the entire system. One of the more effective methods of a convert attack in this space is to attack at the level of the DNS by inserting fake responses in place of the actual DNS response. more

An Internet Security Operations Viewpoint of IGF

The Internet Governance Forum (IGF) is an annual UN conference on Internet governance which was held this year in Rio de Janeiro, Brazil. The topics discussed range from human rights online to providing Internet access in developing countries. A somewhat secondary topic of conversation is Internet security and cyber-crime mostly limited to policy and legislative efforts. Techies and Internet security industry don't have much to do there, but I have a few updates for us from the conference. more

On the Hunt for “Critical Internet Resources”

I'm writing this column in November, and that means that it is time for the traveling circus known as the Internet Governance Forum (IGF) to come down to earth, unpack its tents and sell tickets for its annual song and dance routine. The script for this year's show has been changed, and after being excluded from the main arena last year at the Athens gig, the headline act of "Critical Internet Resources" is taking a starring role this year in Rio. Some folk are even saying that it is the single most contentious issue to be scheduled at this year's IGF show. So what are "Critical Internet Resources" anyway? If folks are going to spend all this time, energy and carbon emissions traveling to Rio to talk on this topic, then wouldn't it be helpful to understand what it means in the first place? There are probably a number of ways to answer this question, so in this heavily opinionated column I'd like to look at the range of possible answers to this question. more

Phishers Now Targeting Domain Registrars

This is an issue of some concern and should be watched carefully: phishers are now trying to get passwords of domain registrants (domain owners). Currently, correspondents inform me that GoDaddy is the target, but there's no reason to think the phishers won't expand to other registrars. Normally, phishers go after bank accounts or other financial information, or sometimes the online accounts of users so that they may send spam. It's not known precisely why phishers are after domain registration information, but the possibilities are chilling... more

Gmail as an Email Honeypot

You all remember cybersquatting, a popular sport in the late 90s, right? McDonalds.com, JenniferLopez.com, Hertz.com and Avon.com thankfully all point to the right web sites today, but thaiairline.com, mcdonald.com, luftansa.com, gugle.com, barnesandnobles.com and other misspellings are fake web sites intended to trap the casual surfer with a hand that's a bit too much quicker than the eye... If you want to go to the McDonalds web site, you don't even spend the 10 seconds to look it up -- you will type McDonalds.com and expect to see the latest dollar meal menu. But the same is true for the other popular form of communication -- email... more

NANOGGING

There are many network operator group meetings being held these days. Even in the backwater of the South Pacific where I live there is now AUSNOG, and NZNOG is just next door in New Zealand. We now have MENOG in the Middle East and AFNOG in Africa. The original NOG was the North American Network Operators Group (NANOG), and they have the T-Shirts to prove it! NANOG meets three times a year, and I attended NANOG 41 in October 2007. NANOG meetings cover a broad variety of topics, from operational tools, measurement, and peering practices through to a commentary on the state of the Internet industry. Here are my impressions of the meeting. more

The “Internet of Things,” the Internet and Internet Governance

As the second Internet Governance Forum approaches, it is an appropriate moment to take stock of how the Internet Governance dialogue has evolved since the conclusion of the WSIS Summit in 2005. One year after the first IGF in Athens, it is clear that government, industry and civil society stakeholders are still grappling over the direction and focus of the IGF... There is little doubt that some governments will choose to borrow concepts from the IGF when developing law and policy and will ultimately apply them to the Internet within their respective jurisdictions. Given the global nature of the Internet, this should be a fundamental concern. While this important dialogue about the Internet continues at the IGF in Brazil next month, another no less important debate is emerging with regard to RFID technology and the so-called "Internet of Things." The Internet of Things is a term coined to describe a future ubiquitous sensor network that collects commercial and personal data in public and private settings created, in part, through the rollout of RFID technology... more

Ameritrade Leaks User Information Yet Again, Blames Hacker X

OK, you know things are getting bad when Ameritrade leaks its customer information yet again, and I don't even bother to report it because it's not news anymore. Well, recent updates to the story have prompted me to correct that omission. Yes, it happened again. Roughly a month ago, correspondents began to receive pump-n-dump spam to tagged email addresses which they had given only to Ameritrade... This now marks the third major confirmed leak of customer information from Ameritrade. In addition, the Inquirer reported the loss of 200,000 Ameritrade client files in February 2005. One correspondent informs me that this has happened to him on four or five previous occasions. more

BMW Goes After BMW.cat

In one of the first (if not the first) UDRP cases for .cat, the auto giant BMW appears to have filed a WIPO case over the BMW.cat domain name. Other prospective new TLD operators have tried to suggest in ICANN meetings that these new TLDs do not cause problems with cybersquatting or defensive registrations... Obviously, given the above WIPO case, that statement is false. more

The Case Against DNSSEC

I was talking to my good friend Verner Entwhistle the other day when he suddenly turned to me and said "I don't think we need DNSSEC". Sharp intake of breath. Transpired after a long and involved discussion his case boiled down to four points: 1. SSL provides known and trusted security, DNSSEC is superfluous, 2. DNSSEC is complex and potentially prone to errors, 3. DNSSEC makes DoS attacks worse, 4. DNSSEC does not solve the last mile problem. Let's take them one at a time... more

Spam: You’ve Come a Long Way, Baby

According to the majority of the testimony at this month's "Spam Summit," held by the U.S. Federal Trade Commission (FTC), the state of the fight against spam is pretty much the same as it has been for the last several years. The two days of presentations can largely be boiled down to the following bullets: Spam volumes continue to increase, being driven by the growth of "botnets"... Oh, and the spam wars are a lot less exciting than they used to be. Case in point: unlike last time, there were no fist-fights at this year's shindig. more

Defending Networks Against DNS Rebinding Attacks

DNS rebinding attacks are real and can be carried out in the real world. They can penetrate through browsers, Java, Flash, Adobe and can have serious implications for Web 2.0-type applications that pack more code and action onto the client. Such an attack can convert browsers into open network proxies and get around firewalls to access internal documents and services. It requires less than $100 to temporarily hijack 100,000 IP addresses for sending spam and defrauding pay-per-click advertisers. Everyone is at risk and relying on network firewalls is simply not enough. In a paper released by Stanford Security Lab, "Protecting Browsers from DNS Rebinding Attacks," authors Collin Jackson, Adam Barth, Andrew Bortz, Weidong Shao, and Dan Boneh provide ample detail about the nature of this attack as well as strong defenses that can be put in place in order to help protect modern browsers. more

Transition to IPv6 Address

Last month's column looked at the exhaustion of the IPv4 unallocated address pool and the state of preparedness in the Internet to grapple with this issue... There has been a considerable volume of discussion in various IPv6 and address policy forums across the world about how we should respond to this situation in terms of development of address distribution policies. Is it possible to devise address management policies that might both lessen some of the more harmful potential impacts of this forthcoming hiatus in IPv4 address supply, and also provide some impetus to industry to move in the originally intended direction to transition into an IPv6 network? more
