Verisign’s Perspective on Recent Root Server Attacks

On Nov. 30 and Dec. 1, 2015, some of the Internet's Domain Name System (DNS) root name servers received large amounts of anomalous traffic. Last week the root server operators published a report on the incident. In the interest of further transparency, I'd like to take this opportunity to share Verisign's perspective, including how we identify, handle and react, as necessary, to events such as this. more

IPv6 Over Satellite: Pie in the Sky?

I am writing this from the Satellite 2008 conference in Washington, D.C. As I make my way through the exhibits, I see many vendors advertising IP capabilities in their hardware products or network services. But when asked about IPv6 support, the common reply is a not so believable "it is on our roadmap" followed by a somewhat vague delivery date. Although IPv6 development has been slow across the board, it appears to be moving even more slowly in the satellite world... 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

Phishers Exploit the Cybercrime Supply Chain Despite the Availability of Effective Countermeasures

Interisle Consulting Group today released its fourth annual Phishing Landscape report investigating where and how cybercriminals acquire naming and hosting resources for phishing. Our study shows that cybercriminals evolved their tactics for obtaining attack resources, including sharply increasing their exploitation of subdomain and gateway providers. more

IPv6 Security Myth #10: Deploying IPv6 is Too Risky

After a quick break to catch our breath (and read all those IPv6 Security Resources), it's now time to look at our tenth and final IPv6 Security Myth. In many ways this myth is the most important myth to bust. Let's take a look at why... Myth: Deploying IPv6 Makes My Network Less Secure... I can hear you asking "But what about all those security challenges we identified in the other myths?" more

Microsoft’s Size Means Malicious Cyber Actors Thrive

Last month, the Russian state-sponsored hacking group "Midnight Blizzard" gained access to the email accounts of Microsoft leadership, even exfiltrating documents and messages. The group reportedly used a simple brute-force style attack to access a forgotten test account and then exploited the permissions on that account to access the emails of employees in the cybersecurity and legal teams. more

Forgotten Principles of Internet Governance

Suddenly internet governance has become a hot topic. Words and phrases fly back and forth but minds rarely meet. We do not have discussion, we have chaos. We are not moving forwards towards a resolution. It's time to step back and review some basic principles. 1. Principle: The internet is here to serve the needs of people (and organizations of people); people are not here to serve the internet. Corollary: If internet technology does not meet the needs of users and organizations than it is technology that should be the first to flex and change. more

Cybersquatting & Banking: How Financial Services Industry Can Protect Itself Online (Webinar)

Businesses in the financial services sector are among the most frequent targets of cybersquatters. In this free webinar, I will be joining Craig Schwartz of fTLD Registry Services to provide important information about how domain name fraud is affecting the financial services industries, including banking and insurance, and what businesses and consumers can do to protect themselves online. more

The London Process Arrived in Budapest: Another Travel Circus for the Internet Community?

The Budapest Conference on Cyberspace brought together nearly 20 heads of states and ministers plus 700 high level experts from various stakeholder groups from 60 countries. However, after two days of discussion there is less clarity where the so-called "London Process" - established by the British Foreign Minister William Hague in November 2011 in London - will go. The next meeting is scheduled for October 2013 in Seoul. Another flying circus for another Internet Governance talking shop? more

Preliminary Thoughts on the Equifax Hack

As you've undoubtedly heard, the Equifax credit reporting agency was hit by a major attack, exposing the personal data of 143 million Americans and many more people in other countries. There's been a lot of discussion of liability; as of a few days ago, at least 25 lawsuits had been filed, with the state of Massachusetts preparing its own suit. It's certainly too soon to draw any firm conclusions... but there are a number of interesting things we can glean from Equifax's latest statement. more

Searching Under Lampposts with DKIM

Email is a complex service and email abuse adds confusing deceptions. Worse, like postal mail and even telephone service, Internet mail is inherently open, flexible and even anonymous, making things much easier for abusers. Bad actors hide their true identity and their true purpose. Most other communication tools for users also are also quite open, and problems with email are being replicated elsewhere, such as instant messaging and social media. more

Botnets Shift Focus to Credential Abuse, Says Latest Akamai Report

Akamai's Fourth Quarter, 2017 State of the Internet, was released today in which it states that the analysis of more than 7.3 trillion bot requests per month has found a sharp increase in the threat of credential abuse, with more than 40 percent of login attempts being malicious. more

Why Are the EU Data Protection Authorities Taking Away Our Fundamental Right to be Safe?

What if we created a rule that gave everyone - good or bad - the right to hide their license plate, where they live, who they are, and just go incognito? What if we made it a right to walk into any building in the world, and simply say "No, thank you" when the security guards asked for one's identification? The criminals would celebrate, and we'd all be utterly alarmed. We would immediately be afraid for our personal safety. more

An Unnatural .Bond: A Study of a ‘Megacluster’ of Malware Domains

A recent news story, following research from security provider Infoblox, highlighted the case of the 'Revolver Rabbit' cybercriminal gang, who have registered more than half-a-million domains to be used for the distribution of information-stealing malware. The gang make use of automated algorithms to register their domains, but unlike the long, pseudo-random ('high entropy') domain names frequently associated with such tools, the Revolver Rabbit domains instead tend to consist of hyphen-separated dictionary words (presumably so as to obfuscate their true purpose), with a string of digits at the end. more

NIS 2.0 and Its Impact on the Domain Name Ecosystem

I recently appeared on the 419 Consulting podcast to discuss the European Union's NIS 2.0 Directive and its impact on the domain name ecosystem. I encourage all TLD registries, domain name registration service providers, and DNS operators to listen to the recording of that session which Andrew Campling has made available. more
