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

Low-Earth Orbit (LEO) Satellite Internet Service Developments for 2020

I posted reviews of important LEO-satellite Internet service developments during 2017, 2018 and 2019. I've updated those posts during the years and have 18 new posts for 2020. In 2020 we saw increased effort from China, OneWeb's bankruptcy and restructuring with new ownership and prospects, Amazon investng in space-related infrastructure, Telesat making steady progress, SpaceX making rapid progress and satellite and debris tracking and collision-avoidsnce service startups. The following are brief summaries of and links to the 2020 posts. more

Nortel… The Good News: Web.Alive

Ok, ok - it's pretty hard to ignore the bombshell news that's on front pages everywhere today in Canada. It looks like Nortel is going to seek bankruptcy protection, perhaps as early as today. This may be a minor story in the U.S. business press, but it's a big story in tech/telecom, and a HUGE story here in Canada. You don't need me to tell you what Nortel means to Canada in terms of pride and joy, although that's more of a distant memory these days... 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

Steering Website Traffic with Managed DNS vs. IP Anycast

I recently read an interesting post on LinkedIn Engineering's blog entitled "TCP over IP Anycast -- Pipe dream or Reality?" The authors describe a project to optimize the performance of www.linkedin.com. The web site is served from multiple web server instances located in LinkedIn's POPs all over the world. Previously LinkedIn used DNS geomapping exclusively to route its users to the best web server instance, but the post describes how they tried using BGP routing instead. more

A Post-Pandemic Look at Owning (Virtual) Space for Business vs Renting on Social Media

Over 20 years ago, in 1997, the very first social media platform, SixDegrees.com, was launched. Most of us have probably not heard of it, and that's not surprising since the platform survived for only four years. Since then, there has been a surge in the number of social media platforms that have been launched: Friendster, MySpace, Foursquare, Classmates, Orkut, Facebook, Twitter, Flickr, Tumblr, Google+, Pinterest, WeChat, Vine, WhatsApp, Blogger, WordPress, LinkedIn, Youtube, TikTok, Instagram, Snapchat, ClubHouse, the list goes on. more

A Look at RFC8200 Which Officially Made IPv6 an Internet Standard

The IETF published RFC8200 last week, which officially makes IPv6 an Internet Standard. While this move was a long time coming -- IPv6 has now reached about 20% deployment -- a more interesting question is: what has changed since RFC2460, which was a draft standard, was published in 2013? After all, the point of moving from the experimental to the draft standard to the internet standard states is to learn more about the protocol as it operates on the wire... more

Internet Pharmacy Safeguards, We Salute You

As I wrote in December 2015, some Internet commerce companies - including domain name registries, registrars, advertising providers, social media platforms, payment processors and shippers - are doing right by patients in taking voluntary action against illegal online drug sellers. This is no small feat as 97% of the roughly 35,000 active online drug sellers are operating illegally. more

Digging Through the Problem of IPv6 and Email - Part 2

We have seen that spammers already possess the ability to hop around IP addresses quickly. They do this because once an IP gets blocked, it is no longer useful to them. There are only so many places they can hide, though - 4.2 billion places they can hide. However, in IPv6, if they are able to do the same pattern of sending out mail and hopping around IP addresses the same way they do in IPv4, then there is virtually unlimited space they can hide in. more

The Netizen’s Guide to Reboot the Root (Part II)

The first part of this series explained how Amendment 35 to the NTIA-Verisign cooperative agreement is highly offensive to the public interest. But the reasons for saving the Internet are more fundamental to Western interests than a bad deal made under highly questionable circumstances. One of the world's foremost experts on conducting censorship at scale, the Chinese Communist Party's experience with the Great Firewall... more

DMARC: New Email Authentication Protocol

A consortium of companies including Google, Microsoft, Facebook and Paypal have announced that they were collaborating and coming up with a new protocol known as DMARC -- the Domain-based Message Authentication, Reporting and Conformance. What is DMARC? more

ccIDNs: So Many Choices, So Little Time

As a result of ICANN's IDN ccTLD Fast Track process, which was launched in November of last year, a number of new ccIDNs (Country Code Internationalized Domain Names) have been successfully added to the root including: China (.??, .??), Egypt (.???), Hong Kong (.?? ), Russia (.??), Saudi Arabia (.????????), Taiwan (.??, .??) and the UAE (.??????). ... With so many new registration possibilities available, and several Sunrise periods quickly approaching, many corporate domain managers are asking themselves whether new registrations should be added to portfolios which are already bursting at the seams. more

Why ICANN Isn’t Being Very Sensible: Part I - .brands

We have long argued that ICANN should consider categories for new gTLDs because different categories will have markedly different benefits and impacts for consumers. It is difficult to represent the complexities of the world in any system and the flat, first come first served single level approach ICANN is proposing is actually more cumbersome, more restrictive, more expensive and less equitable than the very successful existing system it is seeking to extend. 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

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
