Email’s Not Dead, Neither is Spam

Over the past few years, we have seen a plethora of over-hyped articles in the popular press and blogosphere crowing wrong-headedly about how 'email is dead'. Social networks like Facebook and Twitter, new and as-yet unproven technologies are the supposed death-knell for our old reliable friend, e-mail. I wrote about the rumours of email's death being exaggerated back in 2007 in response to such inanity. Since then, we've seen such a cornucopia of silliness of the 'Such & such is killing email' variety that Mark Brownlow compiled a bunch of articles, and their rebuttals at his excellent site... more

BMW Goes After BMW.cat

In one of the first (if not the first) UDRP cases for .cat, the auto giant BMW appears to have filed a WIPO case over the BMW.cat domain name. Other prospective new TLD operators have tried to suggest in ICANN meetings that these new TLDs do not cause problems with cybersquatting or defensive registrations... Obviously, given the above WIPO case, that statement is false. more

Jeff Schmidt to Present Name Collision Management Framework at Research Workshop

I'm delighted to announce that the name collisions workshop this weekend will include Jeff Schmidt, CEO of JAS Global Advisors, presenting the Name Collision Occurrence Management Framework that his firm just released for public review. Jeff's presentation is one of several on the program announced by the program committee for the Workshop and Prize on Root Causes and Mitigations of Name Collisions (WPNC). more

Microsoft Disrupts the Zeus Infrastructure

Over the weekend and this morning, Microsoft, working in conjunction with others, issued civil lawsuits to sinkhole numerous domains associated with the Zeus botnet. When I say "botnet", I use the term loosely because Zeus is not a botnet in the sense that Rustock or Waledac is (or was). Rather, Zeus is a tool kit that online criminals can buy that lets them create phishing pages, perform fast fluxing, host drive-by downloads in addition to spamming. It's more like infrastructure than a botnet, although it does have a large botnet under its control. more

How to Stop the Spread of Malware? A Call for Action

On Webwereld an article was published following a new Kaspersky malware report Q1-2013. Nothing new was mentioned here. The Netherlands remains the number 3 as far as sending malware from Dutch servers is concerned. At the same time Kaspersky writes that The Netherlands is one of the most safe countries as far as infections go. So what is going on here? more

Centralizing the Net, Monetizing DNS, Getting Trendy?

In a Red Herring Conference held last week in California, Mitch Ratcliffe's offers an analytical overview of an interview held with Stratton Scalovs, VerisSign's CEO..."He then goes on to say that we need to move the complexity back into the center of the Net! He says the edge can't be so complex. Get David Isenberg in here! Ross Mayfield, sitting in front of me, laughs out loud. I am dumbfounded. According to VeriSign, the Net should not be open to any type of application, only applications that rely on single providers of services, like VeriSign. This is troglodyte talk." more

Neustar Analysis Shows ICANN Study Overstates Risk of Harmful Domain-Name Collision

As we blogged about recently, Neustar is committed to ensuring that the domain name system is secure and stable and has been operating top-level domains (TLDs) for over a decade. Tuesday, Neustar submitted comments to the Internet Corporation for Assigned Names and Numbers (ICANN) in response to ICANN's proposal to delay the launch of hundreds of new generic top-level domains (gTLDs). ICANN's decision to delay the launch is based on a study it commissioned that measured the potential frequency of domain-name collision. more

IoT in Africa: Urgent Regulation Required

Globally, people are connecting more and more "things" to the Internet. Devices that were traditionally offline or dumb like refrigerators, cars, watches, home cameras, air condition, door locks, agriculture monitoring devices, etcetera, are now being connected to the Internet. This is referred to as the "Internet of Things" (IoT). Using sensors, IoT devices collect data of some sort, which is then most likely shared over a network connection to a service provider, where some analysis is performed on the data. more

ICANN: The Stakes in Registrar Accreditation

Law enforcement demands to domain name registrars were a recurring theme of the 42d ICANN public meeting, concluded last week in Dakar. The Governmental Advisory Committee (GAC) took every opportunity at its public meetings with GNSO and Board, and in its Communique to express dismay, disappointment, and demands for urgent action to "reduce the risk of criminal abuse of the domain name system." more

Are Botnets Really the Spam Problem?

Over the last few years I've been hearing some people claim that botnets are the real spam problem and that if you can find a sender then they're not a problem. Much of this is said in the context of hating on Canada for passing a law that requires senders actually get permission before sending email. Botnets are a problem online. They're a problem in a lot of ways. They can be used for denial of service attacks. They can be used to mine bitcoins... more

Cost-Effectiveness: The Prerequisite for Cybersecurity Regulation

Cybersecurity regulation is coming. Whether regulations intended to enhance critical infrastructure protection will be based on existing statutory authority, new legislation, an Executive Order or a combination of legal authorities, however, is still unknown. Other aspects of the coming federal oversight of critical infrastructure cybersecurity that remain undetermined include the extent to which governance system will include voluntary characteristics and the time frame for initiation of new cybersecurity regulation. more

SPIT is in Everyone’s Mouth, Though Not Yet in Everyone’s Ears

Spam over Internet Telephony (SPIT) is viewed by many as a daunting threat. SPIT is much more fatal than email spam, for the annoyance and disturbance factor is much higher. Various academic groups and the industry have made some efforts to find ways to mitigate SPIT. Most ideas in that field are leaning on classical IT security concepts such as intrusion detection systems, black-/white-/greylists, Turing tests/computational puzzles, reputation systems, gatekeeper solutions, etc... We identified the lack of a benchmark testbed for SPIT as a serious gap in the current research on the matter, and this motivated us at the to start working on a first tool for that. more

Government and Botnets

The US government is looking at telling ISPs how to deal with compromised customers and botnets. They're a bit late to the party, though. Most of the major commercial ISPs have been implementing significant botnet controls for many years now. more

OARC-39: Notes on the Recent DNS Operations, Analysis, and Research Centre Workshop

OARC held its fall meeting in Belgrade on October 22 and 23. Here are my impressions of some of the presentations from that meeting... UI, UX, and the Registry/Registrar Landscape - One of the major reforms introduced by ICANN in the world of DNS name management was the separation of registry and registrar functions. The intent was to introduce competition into the landscape by allowing multiple registries to enter names into a common registry. more

Name Collision Mitigation Requires Qualitative Analysis (Part 3 of 4)

As discussed in the several studies on name collisions published to date, determining which queries are at risk, and thus how to mitigate the risk, requires qualitative analysis. Blocking a second level domain (SLD) simply on the basis that it was queried for in a past sample set runs a significant risk of false positives. SLDs that could have been delegated safely may be excluded on quantitative evidence alone, limiting the value of the new gTLD until the status of the SLD can be proven otherwise. more
