Domain Names Can’t Be Trespassed: Utube.com v. YouTube

Boy, this case got a lot of attention when it was first filed (which isn't surprising; YouTube lawsuits usually do). You may remember the story: the plaintiff is a dealer of used tube mills, used pipe mills and used pollforming machines. The plaintiff operated a website at utube.com. As you might expect, like most other industrial B2B vendors' websites, utube.com had a small but targeted audience. With the phenomenal and quick rise in popularity of YouTube, a lot of web users mistyped youtube.com and entered utube.com instead, causing utube.com to suddenly experience disproportionate popularity. Unfortunately for the plaintiff, few of these visitors were interested in pollforming machines... The plaintiff sued YouTube for trademark infringement... more

Domain Name Association Outlines Healthy Practices as Part of Key Initiative

The domain name system is in good health. But it's about to get even better. The Domain Name Association (DNA), the Internet domain industry's trade association, undertook an effort in 2016 it named the Healthy Domains Initiative (HDI). It's an ambitious, self-motivated effort to build on the DNS' already secure and stable platform and meet select challenges head-on, before they develop. more

A Question of DNS Protocols

One of the most prominent denial of service attacks in recent months was one that occurred in March 2013 between Cloudflare and Spamhaus... How did the attackers generate such massive volumes of attack traffic? The answer lies in the Domain Name System (DNS). The attackers asked about domain names, and the DNS system answered. Something we all do all of the time of the Internet. So how can a conventional activity of translating a domain name into an IP address be turned into a massive attack? 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

An Economic Analysis of Domain Name Policy - Part I

"The Root Server is a Scarce Resource" is the focus of part one of a three-part series based on a study prepared by Karl M. Manheim, Professor of Law at Loyola Law School and Lawrence B. Solum, Professor of Law at University of San Diego. Special thanks and credit to Hastings Communications and Entertainment Law Journal, Vol. 25, p. 317, 2004. ...We begin our analysis of domain name policy with a brief excursion into economics. Economics cannot answer all of the questions raised by domain name policy. First, domain name policy must answer to the discipline of network engineering. A useful domain name system must work, and the functionality, scalability, reliability, and stability of the system are determined by the soundness of its engineering. Second, domain name policy must answer to public policy. The Internet is a global network of networks, and Internet policy is answerable to a variety of constituencies, including national governments, the operators of the ccTLDs, Internet Service Providers, information providers, end users of the Internet, and many others. more

Phishing Attacks Surge Despite Increased Awareness, New Strategies Needed

The alarming rise of phishing attacks has been underscored by a recent study "Phishing Landscape 2023: An Annual Study of the Scope and Distribution of Phishing conducted" by the Interisle Consulting Group, revealing a tripling of such attacks since May 2020. Despite efforts by companies and policymakers to combat this cybercrime, the data suggests that the prevailing strategies are ineffective and worsening each year. more

What Are the Connections to Identified Hafnium Malicious IP Addresses?

Cyber attackers are very skilled at infiltration. They'd find ways into a house through cracks and holes that the homeowner doesn't know about. Analogically speaking, that's what the new cyber attack group dubbed "Hafnium" did when they identified several zero-day Microsoft Exchange vulnerabilities to get into target networks. With thousands of users for every Microsoft Exchange server, the attack has far-reaching implications. First, it establishes the presence of a new threat actor group in town. What else could they be up to? more

Domain Name Typosquatter Still Generating Millions

Ever visit cartoonneetwork.com? Adaptac.com? Check the URLs carefully, for these aren't the "real" sites operated by the Cartoon Network cable channel or by Adaptec, manufacturer of PC storage devices. Instead, these domains -- and some 5,000+ others -- were registered by a Mr. John Zuccarini. Read on to learn what he is up to and how he has gotten away with it. more

A Brief Look at the Domain Attack Surface of Streaming Media Companies

The term "attack surface" is often heard in cybersecurity conversations. It refers to the sum of all possible attack vectors or the vulnerabilities that threat actors can exploit to penetrate a target network or damage an organization somehow. An unused and forgotten subdomain, for instance, can become an attack vector when taken over. Certain categories of companies have very large attack surfaces. Such is the case of streaming media businesses like Netflix and HBO Max. more

PIR’s Anti-Abuse Policy for .ORG Offers No Due Process for Innocent Domain Registrants

PIR, the registry operator for .org, has sent notices to registrars that it is implementing an anti-abuse policy that offers no due process for innocent domain registrants... While it's good intentioned, there is great potential for innocent domain registrants to suffer harm, given the lack of appropriate safeguards, the lack of precision and open-ended definition of "abuse", the sole discretion of the registry operator to delete domains, and the general lack of due process. more
