Trench Warfare in the Age of The Laser-Guided Missile

The historical development of spam fighting is allowing computer-aware criminals to take the upper hand in the fight against what has now evolved into a completely technologically and organizationally merged threat to public safety. If we do not change our strategic approach immediately, the battle, indeed even the war may be all but lost... Of late, much has been said in the popular and computer press about a vector that is annoying, but hardly critical in nature: 'Image spam'. Spammers have jumped on the new technology of 'image-only' payloads, which morph one pixel per message, rendering them unique, and traditional check-sum blocking strategies ineffective... Fortunately this fraudulent stock-touting scheme leaves a paper trail that has allowed for some successful prosecutions in the latter half of the year. Stock spamming, while popular at present time is likely to decline as legal actions increase... more

Taking Back the DNS

Most new domain names are malicious. I am stunned by the simplicity and truth of that observation. Every day lots of new names are added to the global DNS, and most of them belong to scammers, spammers, e-criminals, and speculators. The DNS industry has a lot of highly capable and competitive registrars and registries who have made it possible to reserve or create a new name in just seconds, and to create millions of them per day. Domains are cheap, domains are plentiful, and as a result most of them are dreck or worse. more

Port 25 Blocking, or Fix SMTP and Leave Port 25 Alone for the Sake of Spam?

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

Sex.com Settles Monumental Case Against VeriSign/Network Solutions

Sex.com announced today a final settlement with VeriSign (formerly Network Solutions, Inc.), concluding a six-year legal fight that set several important precedents for the future of the Internet. After the Ninth Circuit Court of Appeals granted Sex.Com a sweeping victory that held VeriSign/Network Solutions, Inc. (collectively "VeriSign") strictly responsible for mishandling the famous domain name, Sex.Com and VeriSign have settled Sex.Com's lawsuit against VeriSign. more

Network Solutions Responds to Front Running Accusations

Following a post on the DomainState forum today, a number news and blogs have criticized Network Solutions for front running domain names that customers try to register. (See for instance today's report on DomainNameNews). Jonathon Nevett, Vice President of Policy at Network Solutions, has offered the following in response to the news break... more

North Dakota Judge Gets it Wrong

Ever been prosecuted for tracking spam? Running a traceroute? Doing a zone transfer? Asking a public internet server for public information that it is configured to provide upon demand? No? Well, David Ritz has. And amazingly, he lost the case. Here are just a few of the gems that the court has the audacity to call "conclusions of law." Read them while you go donate to David's legal defense fund... more

Explaining China’s IPv9

Recently, the news that China is adopting IPv9 is making rounds on the Internet. While some of them write off as an April Fool's joke (in July?) like RFC 1606, other wonders if there are more than meets its eyes. But most of them wonders what is this IPv9 and how does it actually works. And some of the English translated article are so badly done that it is impossible to get any useful technical information except that 'It is developed and supported by Chinese government!' more

Nation of Cameroon Typo-Squats the Entire .com Space

The .cm (Cameroon) ccTLD operators have discovered that since their TLD is simply one omitted letter away from .com, that there is a gold mine in the typo traffic that comes their way. Accordingly, Cameroon has now wild-carded its ccTLD and is monetizing the traffic. The upshot is that, if the Neiman Marcus / Dotster lawsuit over 27 domain names was properly characterized as "massive", then the Cameroonians are now going well beyond massive... more

Top Public DNS Resolvers Compared

At ThousandEyes, we've always been curious about the performance of various public DNS resolvers -- especially since Google threw their hat in the ring back in 2009. We satisfied our curiosity this week, so we thought we'd share the results. Here's how we did it. more

Domain Tasting Target of US Federal Cybersquatting Lawsuit

So Domain Tasting, where registrants (who may also be registrars) taste names and keep only those that have economic value, is now the target of a federal cybersquatting lawsuit, brought about by lawyers for major brand name retailers Neiman Marcus and Bergdorf Goodman against major domain name registrar Dotster. This Dotster lawsuit involves allegations of cybersquatting by registrars who use the Create Grace Period, which is mandated by ICANN for global registries... more

Where are DNS Root Servers? See them on Google Maps

DNS root servers function as part of the Internet backbone, as explained in Wikipedia, and have come under attack a number of times in the past -- although none of the attacks have ever been serious enough to severely hamper the performance of the Internet. In response to some of the common misconceptions about the physical location and total number of DNS root servers in the world, Patrik Faltstrom has put together a visual map on Google, pin-pointing the approximate location of each server around the world. more

Letting DNS Loose

RFID tags, UPC codes, International characters in email addresses and host names, and a variety of other identifiers could all go into DNS, and folks have occasionally proposed doing just that. Its really just a question of figuring out how to use the DNS -- its ready to carry arbitrary identifiers. And by the way, this isn't a new idea, see RFC 1101 for proof, although even earlier I designed the DNS in the early 1980s to allow it to be so, but it seemed too far fetched to document for a while. ...I was in Geneva for a WSIS meeting of CTOs, and was surprised that the various organizations (ITU, ICANN, ISOC) haven't figured out that they need each other to make this technology work, rather than asserting ownership. more

Why I Am Participating in the ORSN Project

As a long time supporter of the universal namespace operated by IANA, it may come as a surprise that I have joined the Open Root Server Network project (ORSN). I'll try to explain what's going on and what it all means. ...If one of my kids, or anybody anywhere, sits down in front of a web browser and keys in a URL, it ought to just work. They ought to see the same web page that anybody else would see, no matter what country they're in or what their ISP wants or what their local church or government wants. This universality of naming is one of the foundations on which the Internet was built, and it is how the Internet fosters economic growth and social freedoms. It's what makes the Internet different from old Compuserve, old AOL, old MSN, old Minitel, and everything else that has come -- and gone -- before... more

DNS Changer

One fine night in November 2011 I got an opportunity to get my hands dirty, working on a project for the United States Federal Bureau of Investigation (FBI). They were planning to seize a bunch of computing assets in New York City that were being used as part of a criminal empire that we called "DNS Changer" since that was the name of the software this gang used to infect a half million or so computers. more

.XXX as Proposed is Wrong for Families & Kids

On August 23rd, the Internet Governance Project posted a letter Opposing Political Intervention in the Internet's Core Technical Administrative Functions. I disagree. ICANN and Governments should get involved when it comes to protecting children online. Every effort should be made to make it SIMPLE for average parents to let their children run free online without the risk of running across pornography and adult material while doing so. Why continue to let pornographers run free and unchecked on the most exciting tool created in the history of mankind just because they got there first? more
