Today's Wall Street Journal discusses the fight over Whois privacy. The article on the front page of the Marketplace section starts by discussing how the American Red Cross and eBay use the Whois database to track down scammers: "Last fall, in the wake of Hurricane Katrina, the American Red Cross used an Internet database called "Whois" that lists names and numbers of Web-site owners to shut down dozens of unauthorized Web sites that were soliciting money under the Red Cross logo. Online marketplace eBay Inc. says its investigators use Whois hundreds of times a day..." more
The House Committee on Science recently held a hearing to "examine the extent of U.S. vulnerability to cyber attacks on critical infrastructure such as utility systems, and what the federal government and private sector are doing, and should be doing, to prevent and prepare for such attacks." Specific issues addressed at the hearing included whether: 1) the U.S. is able to detect, respond to, and recover from cyber-attacks on critical infrastructure; and 2) is there a clear line of responsibility within the federal government to deal with cybersecurity... more
Ah yes, 'Security by obscurity': "Many people believe that 'security through obscurity' is flawed because... secrets are hard to keep." I'm glad the guys guarding the A Root Servers are up on the latest security trends. Of course, you could hide the A Root Servers at the heart of the Minotaur's maze, but they're still going to be "right over there" in cyberspace, at 198.41.0.29 more
Mozilla Foundation has announced changes to Firefox concerning Internationalized Domain Names (IDN) to deal with homograph spoofing attacks. According to the organization, "Mozilla Foundation products now only display IDNs in a whitelist of TLDs, which have policies stating what characters are permitted, and procedures for making sure that no homographic domains are registered to two different entities." Following is a statement explaining the current status of the Mozilla changes to Firefox regarding IDN... more
Despite the significant traffic that comes from typed-in domain names, the public harumphing and clucking about type-in traffic is climbing in volume as it becomes clear how much money is involved. Articles this week show that domain names, and the people who make money on them, are making some commentators uncomfortable. more
Have you ever thought of how reputation is created in cyberspace? Beth Noveck wrote an article, 'Trademark Law and the Social Construction of Trust: Creating the Legal Framework for On-Line Identity' in which she argues that, to determine what rules should govern on-line identity, we should look to trademark law, which has the best set of rules to deal with the way reputation is created in cyberspace. more
The Measurement Factory and Infoblox have announced results of a survey of more than 1.3 million Internet-connected, authoritative domain name system (DNS) servers around the globe. The results of the survey indicate that as many as 84 percent of Internet name servers could be vulnerable to pharming attacks, and that many exhibit other security and deployment-related vulnerabilities. The surveys consisted of several queries directed at each of a large set of external DNS servers to estimate the number of systems deployed today and determine specific configuration details. more
The United States is under cyber-attack. An article in Time magazine titled "The Invasion of the Chinese Cyberspies" discusses a computer-network security official for Sandia National Laboratories who had been "tirelessly pursuing a group of suspected Chinese cyberspies all over the world." The article notes that the cyberespionage ring, known to US investigators as Titan Rain, has been "penetrating secure computer networks at the country's most sensitive military bases, defense contractors and aerospace companies." more
I want to call your attention to a very important Internet free speech decision, perhaps the most significant of our domain name cases from the past several years. In Lamparello v. Falwell, the United States Court of Appeals for the Fourth Circuit held today that the use of the domain name www.fallwell.com for a web site devoted to denouncing the views of Rev. Jerry Falwell about homosexuality neither infringes Falwell's trademark in his name nor constitutes "cybersquatting." more
Everyone is probably well aware of the Kashpureff-style DNS cache- poisoning exploit (I'll call this "classic cache poisoning"). For reference, see the original US-CERT advisory prompted by this exploit. Vendors patched their code to appropriately scrub (validate) responses so that caches could not be poisoned. For the next 7-8 years, we didn't hear much about cache poisoning. However, there was still a vulnerability lurking in the code, directly related to cache poisoning. ...On April 7, 2005, the SANS ISC (not to be confused with Internet Systems Consortium) posted an update detailing how Microsoft Windows DNS servers were still being poisoned, even though the "Secure cache against pollution" option was set. The SANS ISC found that Windows DNS servers using BIND4 and BIND8 servers as forwarders were being poisoned. But how could this be? more
The resale of genuine products presents particular difficulties in domain name disputes, testing the application of fair use doctrine. Several domain name disputes involving the resale of event tickets illustrate the point. I served as a panelist in one such case The Orange Bowl Committee, Inc. v. Front and Center Tickets, Inc., D2004-0947 (WIPO 2005). The decision, which issued with a dissent, explored fair use in the domain name context and addressed several related ticket resale disputes. more
A recent decision by a federal court in Virginia illustrates some interesting legal issues that arise from the global nature of the domain name system. It also highlights a powerful mechanism under the Anticybersquatting Consumer Protection Act ("ACPA") by which a plaintiff can proceed with a legal action to recover a domain name without regard to the court's personal jurisdiction over the registrant. more
I went to Domain Roundtable with some reservations. I was excited about meeting other domain portfolio holders, but I wasn't sure what to expect from the ICANN and Verisign people there, the corporate intellectual property people, and the corporate attorneys. I was pleasantly surprised by everyone I met. more
The following is an overview of the recent Honeynet Project and Research Alliance study called 'Know your Enemy:Phishing' aimed at discovering practical information on the practice of phishing. This study focuses on real world incidents based on data captured and analyzed from the UK and German Honeynet Project revealing how attackers build and use their infrastructure for Phishing based attacks. "This data has helped us to understand how phishers typically behave and some of the methods they employ to lure and trick their victims. We have learned that phishing attacks can occur very rapidly, with only limited elapsed time between the initial system intrusion and a phishing web site going online..." more
Larry Seltzer wrote an interesting article for eWeek, on port 25 blocking, the reasons why it was being advocated, and how it would stop spam. This quoted an excellent paper by Joe St.Sauver, that raised several technically valid and true corollaries that have to be kept in mind when blocking port 25 -- "cough syrup for lung cancer" would be a key phrase... Now, George Ou has just posted an article on ZDNET that disagrees with Larry's article, makes several points that are commonly cited when criticizing port 25 blocking, but then puts forward the astonishing, and completely wrong, suggestion, that worldwide SPF records are going to be a cure all for this problem. Here is my reply to him... more
