2004: The Year That Promised Email Authentication

As the year comes to a close, it is important to reflect on what has been one of the major actions in the anti-spam arena this year: the quest for email authentication. With email often called the "killer app" of the Internet, it is important to reflect on any major changes proposed, or implemented that can affect that basic tool that many of us have become to rely on in our daily lives. And, while many of the debates involved myriads of specialized mailing lists, standards organizations, conferences and even some government agencies, it is important for the free and open source software (FOSS) community as well as the Internet community at large, to analyze and learn lessons from the events surrounding email authentication in 2004. more

Why Vint Cerf is Wrong

At the Internet Governance Forum in Baku, I made an intervention on behalf of NL IGF, reporting on the recommendations given by the participants of Workshop 87... I concluded that more regulatory and law enforcement bodies need to become part of the IGF discussions, as they are an integral part of governing the Internet from a safety and security perspective. Mr. Cerf responded with a one-liner: "I can't help observing, if we keep the regulatories confused, maybe they will leave us alone". more

Patching is Hard

There are many news reports of a ransomware worm. Much of the National Health Service in the UK has been hit; so has FedEx. The patch for the flaw exploited by this malware has been out for a while, but many companies haven't installed it. Naturally, this has prompted a lot of victim-blaming: they should have patched their systems. Yes, they should have, but many didn't. Why not? Because patching is very hard and very risk, and the more complex your systems are, the harder and riskier it is. more

Report on DNS Amplification Attacks

In this newly released paper Randal Vaughn and Gadi Evron discuss the threat of Distributed Denial of Service (DDoS) attacks using recursive DNS name servers open to the world. The study is based on case studies of several attacked ISPs reported to have on a volume of 2.8Gbps. One reported event indicated attacks reaching as high as 10Gbps and used as many as 140,000 exploited name servers. more

TLD for Online Communities and Social Networking?

A company called PW Registry Corporation makes the following announcement regarding the .PW ccTLD originally designated for the country of Palau: "The PW Registry Corporation announced today plans for the activation of the PW top- level domain (TLD), the Internet's first and only domain extension devoted to "Communities of Shared Interests". Unlike other domain extensions, such as .com, .biz, and .info, PW is aimed at providing individuals and consumer/affinity organizations a highly-personalized, permanent and portable e-mail address and a managed platform for community and social networking." more

Temporary Restraining Order Issued Against Domainer’s Use of “mylennar.com”

Companies sometimes find that opportunistic purchasers of domain names (often referred to as "domainers"), will purchase a domain name quite similar to that of the company, and establish a site at the URL loaded with revenue-generating sponsored ads. To accomplish these purposes, domainers seem to prefer the services of companies like HitFarm and Domain Sponsor. A web user types in the confusingly similar URL and is bombarded with pop-up ads and sponsored links to goods and services, often competitive to the company whose name or trademark is being appropriated in the URL... more

3rd Lawsuit Against VeriSign; Seeks Class Action Status

A third lawsuit has been filed late Friday in a federal district court in California against VeriSign, Inc. over its controversial DNS wildcard redirection service known as SiteFinder. It was filed by the longtime Internet litigator Ira Rothken. In addition, while two other lawsuits have been filed by Go Daddy Software, Inc. and Popular Enterprises, LLC. in Arizona and Florida, this is the first lawsuit to seek class-action status. Here is an excerpt from the "Introduction" section of this class-action lawsuit... more

Protecting the Internet: Certified Attachments and Reverse Firewalls?

In many respects the internet is going to hell in a hand basket. Spam, phishing, DNS poisoning, DDoS attacks, viruses, worms, and the like make the net a sick place. It is bad enough that bad folks are doing this. But it is worse that just about every user computer on the net offers a nice fertile place for such ill behavior to be secretly planted and operated as a zombie under the control of a distant and unknown zombie farmer. ...Some of us are coming to the converse point of view that the net is being endangered by the masses of ill-protected machines operated by users. more

The Darkening Web: Is there Light at the end of the Tunnel?

In his book "The Darkening Web: The War for Cyberspace" (Penguin Books, New York 2017), Alexander Klimburg, an Austrian-American academic, gives "Internet Dreamers" a "Wake Up Call". He tells us the background-story why people start to be "anxious about the future of the Internet", as the recent ISOC Global Internet Report "Paths to Our Digital Future" has recognized. Klimburg refers to Alphabets CEO Erich Schmidt, who once said that "the Internet is the first thing that humanity has built that humanity does not understand". more

Update on China SatNet’s GuoWang Broadband Constellation – Can They Do It?

In 2020, China applied to operate GuoWang, a constellation of 12,992 low-Earth orbit (LEO) broadband Internet satellites, and in 2021, it became clear that it was intended to become China’s global LEO broadband constellation. Can they do it? Maybe, but it will take a long time. China does not have the capacity to launch 12,992 satellites today. I don’t know the mass of their planned satellites, but GuoWang is informally referred to as China’s answer to Starlink. more

Donuts to Acquire Afilias

Donuts and Afilias announced today that Donuts is acquiring Afilias in a deal that is expected to close in December 2020 for an undisclosed amount. The combined entities will support over 25 million domain names spanning well over 400 TLDs. The deal will not include certain Afilias businesses, such as the mobile software and registrar businesses, which will remain with Afilias' original group of investors. more

Freedom of Expression Part 2: Blocking, Filtering and Removing Online Content

The Internet is a catalyst for what has revolutionised and transformed human societies in giving extraordinary access to information that has catapulted development and economic growth. It also comes with threats of exploitation by those who wish to do harm. In Part 1 of these series, we looked at how Twitter banned Graham Linehan for his tweet where we saw that to an extent, it was justifiable under Californian law but that a Judge in the Fiji courts would disagree with. more

Valuing IP Addresses

The prospect of exhaustion of the IPv4 address space is not a surprise. We've been anticipating this situation since at least 1990. But it's a "lumpy" form of exhaustion. It's not the case that the scarcity pressures for IP addresses are evidently to the same level in every part of the Internet. It's not the case that every single address is being used by an active device. A couple of decades ago we thought that an address utilisation ratio of 10% (where, for example, a block of 256 addresses would be used in a network with some 25 addressed devices) was a great achievement.  more

Understanding the Threat Landscape: Indicators of Compromise (IOCs)

I previously provided a brief overview of how Verisign iDefense characterizes threat actors and their motivations through adversarial analysis. Not only do security professionals need to be aware of the kinds of actors they are up against, but they should also be aware of the tactical data fundamentals associated with cyber-attacks most commonly referred to as indicators of compromise (IOCs). Understanding the different types of tactical IOCs can allow for quick detection of a breach... more

Google Buys VeriSign (not really)

No that's not really happening, Google is not buying VeriSign. But given Google's ravenous appetite for data, it might find VeriSign quite attractive. VeriSign has both root domain name servers and servers for the .com and .net top level domains (TLDs). VeriSign could data mine the queries coming into those servers and produce a very valuable real-time stream of what users on the net are doing... Google just bought Postini -- and one would have to be fairly naive to believe that Google does not intend to dredge through all... more
