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
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
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
At the 44th Session of the Human Rights Council, we heard how 1 billion children in 2019 who were subjected to various forms of violence and the need for more action to protect children according to the Special Rapporteur. The United Nations Committee on the Rights of the Child released Guidelines on the implementation of the international treaty that bans child pornography, proposing to expand its interpretation to include bans on drawings and stories that sexually depict minors. more
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
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
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
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
Two events, which made headlines in the digital world in 2016, will probably frame the Internet Governance Agenda for 2017. October 1, 2016, the US government confirmed the IANA Stewardship transition to the global multistakeholder community. November 2, 2016, the Chinese government announced the adoption of a new cybersecurity law which will enter into force on July 1, 2017. more
VoIP is here to stay. In fact many incumbent telecommunication carriers have started offering VoIP service for sometime and several new VoIP service providers have emerged. Aside from issues such as quality of service, the aspect of security, or lack thereof, is misunderstood by some of the VoIP service providers. This purpose of this article is to discuss two of the most well known attacks that can be carried out in current VoIP deployments. more
In the case of Lands' End, Inc. v. Remy, the defendant website owners were accused of crafting a clever scheme to get some extra commissions from their affiliate relationship with landsend.com. It looks like the scheme has backfired, however, as Lands' End's claim against the defendants under the Anticybersquatting Consumer Protection Act, [15 U.S.C. §1125(d)] ("ACPA") has survived a summary judgment motion and the case is heading for trial. more
There are now several different courts of appeals that have upheld the right of individuals to post a non-commercial website using the domain name www.company.com, and there are as yet NO appellate decisions that forbid such websites outside the context of the serial cybersquatter who tries to erect a so-called gripe site as a CYA measure after being sued. In fact, it seems to me that we are getting close to the point where companies that sue over such websites have to consider seriously the possibility that they will not only lose the suit, but face a malicious prosecution action... more
In a very casual and low-key footnote over the weekend, ICANN announced it would be further bypassing the Affirmation of Commitments and ignoring the WHOIS Review Team Report. There will be no enhanced validation or verification of WHOIS because unidentified people citing unknown statistics have said it would be too expensive... As a topic which has burned untold hours of community debate and development, the vague minimalist statement dismisses every ounce of work put in by stakeholders. more
After looking at the state of DNSSEC in some detail a little over a year ago in 2006, I've been intending to come back to DNSSEC to see if anything has changed, for better or worse, in the intervening period... To recap, DNSSEC is an approach to adding some "security" into the DNS. The underlying motivation here is that the DNS represents a rather obvious gaping hole in the overall security picture of the Internet, although it is by no means the only rather significant vulnerability in the entire system. One of the more effective methods of a convert attack in this space is to attack at the level of the DNS by inserting fake responses in place of the actual DNS response. more
In our continuing review of Rogue Registrars we have stumbled upon on a very elaborate fake banking site for "Swiss Bank" or "Bank of Switzerland". To the casual Internet consumer this site probably appears legitimate, but a number of clues tip off the fraud. Phishing sites are everywhere so this does not immediately raise eyebrows until you review the Thick WHOIS record for the domain. more
