IPv6 represents new territory for most Internet stakeholders, and its rollout will introduce some unique security challenges.

Watching North Korea's Internet Connectivity Go Up and Down Via Twitter

One thing I enjoy about following Dyn Research (formerly Renesys) on Twitter is that they provide quite interesting graphics and charts about Internet outages. They've been tracking North Korea's Internet access quite closely over the past week and their tweets have been quite enlightening. Back on December 22, for instance, DynResearch tweeted a chart showing a 9-hour, 31-minute outage... more»

Wait and See Approach on Abuse

Wait and see approach on abuse attracts ICANN Stakeholder attention: A few weeks ago I made a detailed argument as to why product safety applies to domains, just like it does to cars and high chairs. I also argued that good products equal good business or "economically advantaged" in the long run. Then I really made a strong statement, I said if we don't actively engage other Internet stakeholders -- those that interact with our products, we would eventually lose the opportunity to self-regulate. more»

One Year Later: Lessons Learned from the Target Breach

As the autumn leaves fall from naked trees to be trampled or encased in the winter snow, it reminds us of another year quickly gone by. Yet, for organisations that were breached and publicly scrutinised for their security lapses, it's been a long and arduous year. It was about this time last year that the news broke of Target's mega breach. Every news outlet was following the story and drip feeding readers with details, speculation and "expert opinion" on what happened, why it happened and who did it. more»

Call For Participation - ICANN 52 DNSSEC Workshop on 11 Feb 2015 In Singapore

If you will be at ICANN 52 in Singapore in February 2015 (or can get there) and work with DNSSEC or the DANE protocol, we are seeking proposals for talks to be featured as part of the 6-hour DNSSEC Workshop on Wednesday, February 11, 2015. The deadline to submit proposals is Wednesday, December 10, 2015... The full Call For Participation is published online and gives many examples of the kinds of talks we'd like to include. more»

Which Domains Stand the Strongest Against Phishing Attacks?

The latest Anti-Phishing Working Group (APWG) Global Phishing Survey, which analyzed over 100,000 phishing attacks in the first half of 2014, examines the progress that top level domains (TLDs) are making in responding to phishing attacks that use their TLDs. The report finds the .INFO domain has the lowest average phishing uptimes as compared to other TLDs, such as .COM and .NET. more»

Nameserver Operators Need the Ability to "Disavow" Domains

Yesterday's DDoS attack against DNSimple brought to light a longstanding need for DNS nameserver operators to have an ability to unilaterally repudiate domains from their nameservers. The domains under attack started off on DNSMadeEasy, migrated off to DNSimple and took up residence there for about 12 hours, causing a lot of grief to DNSimple and their downstream customers. more»

Domain Name Abuse Is a 4 Letter Word

There has been a lot of back and forth recently in the ICANN world on what constitutes domain abuse; how it should be identified and reported AND how it should be addressed. On one side of the camp, we have people advocating for taking down a domain that has any hint of misbehaviour about it, and on the other side we have those that still feel Registries and Registrars have no responsibility towards a clean domain space. (Although that side of the camp is in steady decline and moving toward the middle ground). more»

Secure Unowned Hierarchical Anycast Root Name Service - And an Apologia

In Internet Draft draft-lee-dnsop-scalingroot-00.txt, I described with my coauthors a method of distributing the task of providing DNS Root Name Service both globally and universally. In this article I will explain the sense of the proposal in a voice meant to be understood by a policy-making audience who may in many cases be less technically adept than the IETF DNSOP Working Group for whom the scalingroot-00 draft was crafted. I will also apologize for a controversial observation concerning the addition of new root name servers... more»

Bashbleed - A Nasty Reminder Never to Forget Security 101

After the botched burglary at the Watergate Apartments, every scam and scandal that hit the headlines became a 'gate' -- Irangate, Contragate, you name it. The Heartbleed bug is possibly the closest thing to Watergate that this generation of computer security had seen till the past few days -- an exploit in a component that is "just there" -- something you utterly rely on to be there and perform its duties, and give very little thought to how secure (or rather, insecure) it might be. So, fittingly, every such catastrophic bug in an ubiquitous component is now a 'bleed'. more»

Verisign Mitigates 300 Gbps DDoS Attack and Other Q2 2014 DDoS Trends

It has been another busy quarter for the team that works on our DDoS Protection Services here at Verisign. As detailed in the recent release of our Q2 2014 DDoS Trends Report, from April to June of this year, we not only saw a jump in frequency and size of attacks against our customers, we witnessed the largest DDoS attack we've ever observed and mitigated -- an attack over 300 Gbps against one of our Media and Entertainment customers. more»

Anti-Spoofing, BCP 38, and the Tragedy of the Commons

In the seminal 1968 paper "The Tragedy of the Commons" , Garrett Hardin introduced the world to an idea which eventually grew into a household phrase. In this blog article I will explore whether Hardin's tragedy applies to anti-spoofing and Distributed Denial of Service (DDoS) attacks in the Internet, or not... Hardin was a biologist and ecologist by trade, so he explains "The Tragedy of the Commons" using a field, cattle and herdsmen. more»

Senate Judiciary Committee Hearing on Botnet Takedowns (July 15, 2014)

The background is of course quite interesting, given how soon it has followed Microsoft's seizure of several domains belonging to Dynamic DNS provider for alleged complicity in hosting trojan RAT gangs, a couple of days after which the domains were subsequently returned -- without public comment -- to Vitalwerks, the operator of No-IP. This is by no means a new tactic for Microsoft, who has carried out successful seizures of various domains over the past two or three years. more»

Microsoft's Takedown of - A Gigantic Self Goal?

I will first begin this post by emphasizing that this article is entirely my personal viewpoint and not to be considered as endorsed by or a viewpoint of my employer or any other organization that I am affiliated with. Neither is this to be considered an indictment of the sterling work (which I personally value very highly) that several people in Microsoft are doing against cybercrime. Microsoft's takedown of to disrupt the Nitol botnet is partial and will, at best, have a temporary effect on the botnet itself... more»

Is Your New TLD Protected Against Phishing and Malware?

Until now, the criminals behind malware and phishing have had only 22 generic top-level domain names (TLDs) to abuse -- names like .com, .net or .org. But with hundreds of new TLDs entering the marketplace, e.g. .buzz, .email, and .shop, there are many more targets than ever... What can attackers do with domain names? more»
