Brand Complementors: Implementing a Cooperative Domain-Name Use

The essay expands a cooperative solution to third-party use of brands in domain names. Like any approach that depends on cooperation, the solution will require both sides to change behavior but also allow both sides to take credit for the resulting benefits, i.e. a triangular solution. If not immediately addressed, the problem of third-party use can become a major threat to the industry. But we already know one thing: when it comes to this issue, legal action and bullying don't work. more

There Is No “Spam Problem”

This month I thought I could feel smug, deploying Postfix, with greylisting (Postgrey), and the Spamhaus block list (SBL-XBL) has reduced the volume of unsolicited bulk commercial email one of our servers was delivering to our clients by 98.99%. Alas greylisting is a flawed remedy, it merely requires the spambots to act more like email servers and it will fail, and eventually they will... more

DNSSEC Update from ICANN 42 in Dakar

While the global rollout of DNSSEC continues at the domain name registry level - with more than 25% of top-level domains now signed - the industry continues to focus on the problem of registrar, ISP and ultimately end-user adoption. At the ICANN meeting in Dakar in late October, engineers from some of the early-adopting registries gathered for their regular face-to-face discussion about how to break the "chicken or egg" problems of secure domain name deployment. 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

Why I Voted for .XXX

The ICANN Board voted today 9-5, with Paul Twomey abstaining, to reject a proposal to open .xxx. This is my statement in connection with that vote. I found the resolution adopted by the Board (rejecting xxx) both weak and unprincipled... I am troubled by the path the Board has followed on this issue since I joined the Board in December of 2005. I would like to make two points. First, ICANN only creates problems for itself when it acts in an ad hoc fashion in response to political pressures. Second, ICANN should take itself seriously as a private governance institution with a limited mandate and should resist efforts by governments to veto what it does. more

GDPR PII Time-Bomb? Kill it With Fire!

Hi! My name is spamfighter. I investigate spam and phish in a post-GDPR dystopia. Recently, I invented Fire, to save you millions of €uros. One day, my Boss suggested I automate some of my processes. I, for one, welcome our Robot Overlords (and a happy boss), but I can be exacting about the tools I use. Perhaps not to the degree of the infamous Van Halen 'no brown M&M's' contractual clause but I have no patience for poorly-designed software, and truly dislike typing when... more

EFF on Goodmail: Further Confusing an Already Confused Issue

Cindy's piece on the EFF website seems to be a bit of a pastiche, with elements taken out of various articles (some outright wrong, some merely misinformed) that have been doing the rounds of the media for quite a while now about Goodmail. She started off comparing AOL and Goodmail with the old email hoax about congress taxing email. That same line was used in a CircleID post by Matt Blumberg, CEO & Chairman of Returnpath... Various other quotes from different places - Richard Cox from Spamhaus on CNN for example. However a lot of the quotes in those articles are being based on wrong or out of context assumptions, starting with one that goes "AOL is going to remove all its existing whitelists and force people to use Goodmail". more

The Criminals Behind WannaCry

359,000 computers infected, dozens of nations affected world-wide! A worm exploiting a Windows OS vulnerability that looks to the network for more computers to infect! This is the most pernicious, evil, dangerous attack, ever... Queue the gnashing of teeth and hand-wringing! Wait, what? WannaCry isn't unprecedented! Why would any professional in the field think so? I'm talking about Code Red, and it happened in July, 2001. more

Skype as a Platform for Secure VPN Tunnels?

Since Skype has an open client-side API, why not use it as a transport to tunnel VPN traffic and blow through firewalls to connect you to a remote system? That's the idea raised by Peeter P. Mõtsküla in his Skype Developer Blog entry: "Idea: skypetunnel". For instance, have a Skype client running on your home machine logged in as one account. Have Skype on your laptop on another account. Initiate a connection between the two of them and wind up with secure, encrypted access through the firewall from wherever you are. Being peer-to-peer, there would be no central servers or infrastructure required (outside the usual Skype p2p cloud.) This would require, of course, a yet-to-be-created "extra" that connected into the Skype client API and was installed on both systems...but that was the point of the article... more

DNSSEC No Longer Pie-in-the-Sky: Time to Develop a Strategy

You may have seen media reports a few weeks ago describing how servers behind the so-called Great Firewall of China were found delivering incorrect DNS information to users in the rest of the world, thereby redirecting users to edited Web pages. Reports indicate that this apparently occurred due to a caching error by a single Internet Service Provider. While the problem was fairly limited in scope, it could have entirely been prevented in a world where DNSSEC was fully deployed. more

Petition Against Site Finder

We Internet users, who either own domain names or have an interest in the domain name system, wish to object to the VeriSign's Site Finder system. We believe that the system: 1) Breaks technical standards, by rewriting the expected error codes to instead point to VeriSign's pay-per-click web directory, and threatens the security and stability of the Internet; 2) Breaks technical standards affecting email services, and other Internet systems... more

Analyzing Data for Business and Security Signals

Domain name registries and registrars play a critical role in the functioning of the internet, serving as gatekeepers to the DNS. As such, they have an important responsibility to ensure the security and stability of the DNS but also to promote the use of a domain name in a meaningful way for the end user. To be more efficient in achieving these goals, the domain name industry has started to become more open to the idea of leveraging their own internal data to gain insights about their current business. more

Legal Controls on Extreme End-to-End Encryption (ee2ee)

One of the most profoundly disruptive developments occurring in the cyber security arena today is the headlong rush by a set of parties to ubiquitously implement extreme End-to-End (e2e) encryption for communication networks using essentially unbreakable encryption technology. A notable example is a new version of Transport Layer Security (TLS) known as version 1.3. The activity ensues largely in a single venue... more

ICANN Ordered by Illinois Court to Suspend Spamhaus.org

Apparently, at this stage, it is only a proposed ruling. But I am no lawyer. This story has been discussed before, when Spamhaus, which is located in the UK, was sued in the US by a spammer. They refused to come before the court as "they do no business in Illinois, and are located in the UK...After this court ruling, Spamhaus.org was under a DDoS attack, in my opinion for the purpose of preventing users from reaching the information it provided about the court ruling. This was done along-side a Joe Job, sending fake email appearing to come from Spamhaus's CEO... more
