Bit.ly Gets You Blocked

URL shorteners, like bit.ly, moby.to and tinyurl.com, do three things... Making URLs shorter was their original role, and it's why they're so common in media where the raw URL is visible to the recipient -- instant messaging, twitter and other microblogs, and in plain text email where the "real" URL won't fit on a single line. From the moment they were invented they've been used to trick people to click on links to pages they'd rather not visit... more

Canada Finishes its Spam Task Force, Result is Pretty Good

Industry Canada, the part of the Canadian government roughly equivalent to the U.S. Commerce Department, has had a task force on spam working for the past year or so. I was invited to participate as an unofficial member, since I'm not a Canadian. Yesterday, it wrapped up its work and published its report (aussi disponsible en francais) to the government. It's quite good, and has a set of 22 recommendations. more

Two Stage Filtering for IPv6 Electronic Mail

I'm a guest at the MAAWG conference in San Francisco this week and several people have now mentioned to me the problem and the opportunity of anti-spam e-mail filtering for IPv6. Tomorrow is World IPv6 Day but since a bunch of the pieces have clicked together in my head I'll post this a day early. more

ICANN Approves New Domain for Adult Sites

The Board of Directors of the Internet Corporation for Assigned Names and Numbers (ICANN) has determined that the proposal for a new top level domain submitted by ICM Registry, Inc. has met the criteria established by ICANN. Accordingly, ICM Registry will now move forward into technical and commercial contractual negotiations with ICANN to generate a voluntary .xxx top-level domain (TLD). more

DNSSEC: Will Microsoft Have Enough Time?

I have previously pointed out the shortcomings of good and user friendly support for DNSSEC in Microsoft's Server 2008 R2. During the period just after I wrote the post, I had a dialogue with Microsoft, but during the last months there has been no word at all. The reason I bring this up again is that more and more Top Level Domains (TLDs) now enable DNSSEC and also the fact that within six months the root will be signed. more

IPv6 Adoption Brings New Security Risks

Although IPv6 DDoS attacks are not yet a common occurrence, there are indications that malicious actors have started testing and researching IPv6 based DDoS attack methods. more

UK’s Government Websites Infected by Cryptocurrency Mining Malware

Thousands of websites are reported to have been infected by malware over the weekend forcing visitors' computers to mine cryptocurrency while using the sites. more

Success Drivers of New gTLD Applications

Being approved by the Internet Corporation for Assigned Names and Numbers (ICANN) as the owner of a new generic top-level domain (gTLD) extension requires considerable analysis before the application is submitted. You must understand the sources of risk, gauge your risk tolerance, and you must obtain an estimate of the value of your proposed TLD's future revenues (with the effects of potential competitors factored in, a step too many applicants ignore). more

Measuring the Use of DNSSEC

The canonical specification of the DNS that is normally cited are the pair of quite venerable RFCs, RFC 1034, "Domain names - concepts and facilities", and RFC 1035, "Domain names - implementation and specification", both published in November 1987. However, these two specification documents are just the tip of a rather large iceberg. One compendium of all the RFCs that touch upon the DNS lists some 292 RFCs. more

Internet Society Extends Its Significant Financial Support Commitment to the IETF

According to an announcement on Monday, the Internet Society has agreed to extend its existing financial commitment to the Internet Engineering Task Force (IETF) for an additional term of six years. more

The Design of the Domain Name System, Part I

Over the past 30 years the Domain Name System has become an integral part of the operation of the Internet. Due to its ubiquity and good performance, many new applications over the years have used the DNS to publish information. But as the DNS and its applications have grown farther from its original use in publishing information about Internet hosts, questions have arisen about what applications are appropriate for publication in the DNS, and how one should design an application to work well with the DNS. more

How Big Is the Domain Business?

When you're standing close to ICANN, the domain business may seem pretty big, but when you stand farther away, not so much. Verisign's revenues are about $1 billion/year. The .COM and .NET top-level domains together have about 150M names. The next biggest gTLDS are .ORG with 25M and .INFO with 12M. The biggest new TLDs are TOP with 2.9M and .XYZ with 1.8M, with both bloated by firesale prices. The rest are smaller, mostly much smaller. more

The Highest Threat TLDs - Part 1

A domain name consists of two main elements: the second-level domain name to the left of the dot - often consisting of a brand name or relevant keywords - and the domain extension or top-level domain (TLD) to the right of the dot. Domain names form the key elements of the readable web addresses allowing users to access pages on the internet and also allowing the construction of email addresses. more

Why Vint Cerf is Wrong

At the Internet Governance Forum in Baku, I made an intervention on behalf of NL IGF, reporting on the recommendations given by the participants of Workshop 87... I concluded that more regulatory and law enforcement bodies need to become part of the IGF discussions, as they are an integral part of governing the Internet from a safety and security perspective. Mr. Cerf responded with a one-liner: "I can't help observing, if we keep the regulatories confused, maybe they will leave us alone". more

2004: The Year That Promised Email Authentication

As the year comes to a close, it is important to reflect on what has been one of the major actions in the anti-spam arena this year: the quest for email authentication. With email often called the "killer app" of the Internet, it is important to reflect on any major changes proposed, or implemented that can affect that basic tool that many of us have become to rely on in our daily lives. And, while many of the debates involved myriads of specialized mailing lists, standards organizations, conferences and even some government agencies, it is important for the free and open source software (FOSS) community as well as the Internet community at large, to analyze and learn lessons from the events surrounding email authentication in 2004. more
