Moving Target: Spammer Using Over 1000 Home Computers as DNS

Some individual appears to have hijacked more than a 1,000 home computers starting in late June or early July and has been installing a new Trojan Horse program on them. The Trojan allows this person to run a number of small websites on the hijacked home computers. These websites consists of only a few web pages and apparently produce income by directing sign-ups to for-pay porn websites through affiliate programs. Spam emails messages get visitors to come to the small websites.

To make it more difficult for these websites to be shut down, a single home computer is used for only 10 minutes to host a site. After 10 minutes, the IP address of the website is changed to a different home computer... more

Analyzing The Inbox of a Spammer’s Domain

Consider this scenario: you need a domain name for your site so you go to your favorite domain registrar's website and upon a quick search find that your third choice is actually available! You quickly pull your credit card and register the name. Everything is good and you can't wait to have your new domain start pointing to your site and represent your official email address. But not so fast -- some of the recent events are revealing that, these days, when you are registering a domain name there is one more critical thing you need to do: check under the hood! more

Fight Spam With the DNS, Not the CIA

It seems like spam is in the news every day lately, and frankly, some of the proposed solutions seem either completely hare-brained or worse than the problem itself. I'd like to reiterate a relatively modest proposal I first made over a year ago: Require legitimate DNS MX records for all outbound email servers.

MX records are one component of a domain's Domain Name System (DNS) information. They identify IP addresses that accept inbound email for a particular domain name. To get mail to, say, linux.com, a mail server picks an MX record from linux.com's DNS information and attempts to deliver the mail to that IP address. If the delivery fails because a server is out of action, the delivering server may work through the domain's MX records until it finds a server that can accept the mail. Without at least one MX record, mail cannot be delivered to a domain.

Montreal ICANN Meetings Creating Some Irritations

Two controversial issues which were on the agenda of the Montreal ICANN meetings creating some irritation: the way of planning to create a country code support organization (ccNSO), and the discussions around the purpose and operation of WHOIS – the database of registrants of domains. Without going into the history of the ccTLDs withdrawing from their former role within the DNSO and moving towards a self organized structure, there is an obvious conflict revolving around the term... more

With No Privacy Standards Who Knows Who Is Abusing The Whois Database

John Banks is a loan officer in New York. John's supervisor recently warned John about the potential number of bad loans he may be carrying as part of his portfolio. To dump some of the bad loans he might be carrying, John came up with a scheme. He pointed his web browser to www.whois.org and entered terms denoting disease or poor health such as 'cancer' and 'illness'. This query on the Internet's WHOIS database reported results of names and addresses of domain name owners who had developed websites devoted to providing information on certain serious illnesses. John compared these names and addresses with those in his portfolio of loans. For the matches, he canceled the loans and required immediate payment-in-full. more

Time For ICANN/IANA To Squarely Face The Question Of Privacy

Various people whose judgment I value [M. Mueller, B. Fausett] have suggested that ICANN/IANA may finally get to the issue of privacy.

The ICANN Board is establishing a "President's Standing Committee on Privacy" (why the committee is possessed by ICANN's "president" and not the Board is something we can deal with at another time and another place.)

Privacy is a hard question. It is a matter that pervades all aspects of information handling. It would be entirely inappropriate, and ultimately futile, to try to deal with privacy as an after-the-fact adjustment to the existing DNS Whois system. It is necessary to examine the most fundamental questions -- such as what reasons, if any, justify there being a Whois database at all. more

98% Of Internet’s Main Root Server Queries Are Unnecccary: Should You Be Concerned?

A recent study by researchers at the Cooperative Association for Internet Data Analysis (CAIDA) at the San Diego Super Computer Center (SDSC) revealed that a staggering 98% of the global Internet queries to one of the main root servers, at the heart of the Internet, were unnecessary. This analysis was conducted on data collected October 4, 2002 from the 'F' root server located in Palo Alto, California.

The findings of the study were originally presented to the North American Network Operators' Group (NANOG) on October 2002 and later discussed with Richard A. Clarke, chairman of the President's Critical Infrastructure Protection Board and Special Advisor to the U.S. President for Cyber Space Security. more

Is Whois Data Accuracy Enough?

The Whois Task Force of the Domain Name Supporting Organization (DNSO) has been consulting with registrars over the past few months on the Whois accuracy issue for law enforcement. The Task Force has enumerated three primary areas of interest: accuracy, uniformity, and better searching capabilities. When the registrars met with the Task Force in Shanghai, a fourth area of interest was also brought forward and advocated by many of the registrars at the meeting as paramount to the other three areas. This fourth area of interest was privacy. more

Privacy Matters: Is It Time To Abolish The WHOIS Database?

Recently, I entered my domain name in a "WHOIS" database query to test the results of the database by using WHOIS on a number of domain name registrar websites. WHOIS is a database service that allows Internet users to look up a number of matters associated with domain names, including the full name of the owner of a domain name, the name of the domain name hosting service, the Internet Protocol or I.P. number(s) corresponding to the domain name, as well as personally identifying information on those who have registered domain names. I was astonished to find... more

Parsing Hype From Hope: Will ENUM Spark Changes In Telecom?

In the beginning there was silence; then, silence begat communication, and communication begat more communication and, ultimately, group communication formed and begat a primordial "network" of communication that gradually and inevitably increased in effectiveness and complexity: there were only signal fires at first but, then, there were cave drawings, carrier pigeons, shouting from hill-tops, smoke from fire, lines of cannon fire, the telegraph, Alexander Graham Bell, and, finally, the network of networks known as the Internet. But, is that it? Is there not something more impressive in its impact upon communication than the Internet? What more might one desire than the dynamic wonders of the Internet, you ask? Well, what about ENUM? "E-What!?" more
