Uprooting of the DNS Root

The folks at Renesys pointed out earlier this week some interesting activity surrounding the L-root name server, highlighting some activity that should give us all yet another reason to be concerned about the security and integrity of the Internet DNS... considering that a great deal of malware today tends to corrupt the DNS resolution path in order to further exploit compromised end-systems, and that corruption, or any other actual end-system compromise, might well be unnecessary if the root were compromised -- well, think of the possibilities! 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

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

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

The Extent of DNS Services Being Blocked in China

The most recent episode of The Ask Mr. DNS Podcast offers up some disturbing corroborating evidence as to the extent of DNS filtering and outright blocking occurring in China. VeriSign's Matt Larson and InfoBlox's Cricket Liu, who co-host the geeky yet engaging and extremely informative show, held a roundtable discussion including technical experts from dynamic name service providers (better known as "managed DNS" services) DynDNS, TZO, No-IP, and DotQuad, as well as Google and Comcast. 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

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

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

Internet Governance Outlook 2018: Preparing for Cyberwar or Promoting Cyber Détente?

In 2018, Internet Governance will be one of the top priorities in the geo-strategic battles among big powers. In today's world, every global conflict has an Internet-related component. There is no international security without cybersecurity. The world economy is a digital economy. And human rights are relevant offline as well as online. It is impossible to decouple cyberspace from the conflicts of the real world. 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

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

Follow a Phishing Case in Real Time: postfinances.com / Swiss Post

It is just another phishing case. Why should I care? I happened to receive my own copy of the phishing email message. Most Internet users will just smile bitterly before deleting it. I checked it to see why it had gone through the spam filters. It had no URL in the text but a reply-to address. So it needed a valid domain name, and had one: postfinances.com. PostFinance (without trailing "s") is the payment system of the Swiss Post. It has millions of users. more

A Safe Pharmacy Environment in the Digital Age

Today's ever-evolving, digital world has fundamentally changed, enhanced and challenged the way in which businesses all over the world must operate. For organizations and professions that have existed for centuries, this has created the opportunity and the test of adapting to change to remain successful and relevant. The National Association of Boards of Pharmacy (NABP) was founded in 1904, at a time when there was little uniformity in the practice of, or standards for pharmacy. 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
