Revisiting How Registrants Can Reduce the Threat of Domain Hijacking

Recent events have shown the threat of domain hijacking is very real; however, it is also largely preventable. As Verisign previously noted, there are many security controls that registrants can utilize to help strengthen their security posture. Verisign would like to reiterate this advice within the context of the recent domain hijacking reports. Domains are an important element of internet infrastructure; their functionality and security rely upon many factors such as their delegated name servers. more

Authorities Take Down the Mariposa Botnet

There are a number of sources talking about the takedown of the Mariposa botnet... Spanish authorities, working with researchers from Panda Labs, Defence Intelligence and a couple of other educational institutions, took down the Mariposa botnet (Mariposa is the Spanish word for "butterfly"). The Mariposa botnet is an absolutely enormous with around 12 million (!) nodes doing its bidding. It was involved in things like credit card phishing and identity fraud. more

ICANN Bans Dotless Domains

Any new top level domain approved for the Internet will have to be more than just a single label. ICANN's new gTLD program committee (NGPC) has decided to ban the use of "dotless domains". TLD operators that had planned to use their new suffix as a keyword, i.e. just the string and nothing else, will now have to reconsider. 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

Metrics of Major Standards Bodies

In a recent CircleID posting related to the ITU-T, the demise of that body over the years and the underlying causes were described. Among other questions, it raises the question of where has the industry technical collaborative activity gone. The short answer is just about everywhere else. This was exemplified by a recently compiled spreadsheet of some 200 different cloud forums prepared by the ITU-T's own cloud coordination group. more

The Economics of Hacking an Election

There have been many news stories of late about potential attacks on the American electoral system. Which attacks are actually serious? As always, the answer depends on economics. There are two assertions I'll make up front. First, the attacker -- any attacker -- is resource-limited. They may have vast resources, and in particular, they may have more resources than the defenders -- but they're still limited. Why? more

An Introduction to Security and Reliability - What Does It Really Mean?

I co-authored a book in 2005, titled "Extreme Exploits: Advanced Defenses Against Hardcore Hacks." My chapters focused on securing routing protocols such as BGP, and securing systems related to DMZs, firewalls, and network connectivity. As I look back over those chapters, I realize that the basic fundamentals of network security really haven't changed much even though technology has advanced at an incredible pace. "Defense in depth" was a hot catch phrase seven years ago, and it still applies today. more

Competition for Monopoly gTLDs

The essay examines some of the new domain name managers' unjustifiable obsession with owning monopoly gTLDs when they should devote more energy and thought to making domain names more value adding. For the last three decades, the discourse regarding competitive advantage has focused on the need to rely on rare/unique resources and capabilities. However, more recently, the focus has shifted to the imperatives of efficient utilization of nonunique resources... more

An Account of the Estonian Internet War

About a year ago after coming back from Estonia, I promised I'd send in an account of the Estonian "war". A few months ago I wrote an article for the Georgetown Journal of International Affairs, covering the story of what happened there. This is the "war" that made politicians aware of cyber security and entire countries scared, NATO to "respond" and the US to send in "help". It deserved a better understanding for that alone, whatever actually happened there. more

DOTZON Study: Digital Company Brands 2021

DOTZON presents the fourth edition of the Digital Company Brands study. After having introduced the study in 2018, DOTZON continued to expand and enhance the underlying data to display how cities successfully use their Digital Company Brands. The Digital Company Brand is the digital dimension of a company brand and mirrors the "digitalness" of a company. Purely digital company brands developed for the first time in the 1990s, with the emergence of Internet business models. Some of them were based solely on a generic Internet address, for example, www.hotel.de or www.amazon.com. more

The FCC is Taking the Right Step

Today's announcement from the Commission that it intends to roll back the exercise of Title II utility-style regulation over "any person engaged in the provision of broadband internet access service" at its 14 December meeting is the right step. As a veteran of 40 years of internet related regulatory wars in the FCC and numerous other venues, the Commission's decision and the actual Rules promulgated in the February 2015 Report & Order stand among the most ill-considered application of authority and regulatory gerrymandering ever witnessed. more

ICANN 44 Prague: A Look at the Future

ICANN's 44th public meeting is about to start in a few days with a number of topics on the agenda. Some of them are new, while some of them are ongoing. First off, ICANN will be announcing the new CEO this Friday afternoon in Prague. Whoever it is will be coming to the organisation at a time when it faces a number of significant challenges. While the actual official meeting does not start until Monday morning there will be plenty of meetings on over the weekend as well... So what's on the "menu" for Prague? more

Spam Is on the Decline; What Are the Implications?

Previously, I wrote that the total amount of spam that we are seeing has seen a significant decline over the past year and a half. What does this mean in real terms? Are we finally winning the fight against spam? There are multiple angles. On the one hand, processing spam takes significant system resources... more

Analysis of the Global IT Breakdown Caused by Microsoft-CrowdStrike

The Optus outage in Australia from last year was immediately on my mind when on Friday afternoon a similar event swept, this time, across the world. Also, in this case it was a software update that caused the problem. This time from global security software provider CrowdStrike. The culprit appears to be an update to the CrowdStrike Falcon platform, a security monitoring tool widely deployed by businesses and organisations on Microsoft desktop computers and notebooks. more

Raspberries! Botnet Spam Just Got a Whole Lot More Dangerous

Many have heard of botnets, but for those that aren't certain what they are: Botnets are armies of hacked zombie computers that have malware on them, and send spam email at the command of operators anywhere in the world. They can also be told to deploy denial of service attacks, by all hitting the homepage of a given company, or attacking the DNS server or a service or country. more
