Why Isn’t Mobile Malware More Popular?

This is a followup to Wout de Natris' as usual excellent piece on the Enisa botnet report -- pointing out the current state of mobile malware and asking some questions I started off answering in a comment but it grew to a length where I thought it'd be better off in its own post. Going through previous iterations of Mikko's presentations on mobile malware is a fascinating exercise. more

Interesting Facts About Domain Names

During a database testing, Dennis Forbes makes use of the .com zone file as data sample but he also stumbles upon some unexpected domain name discoveries which he has reported on his site. Dennis Forbes explains: "I recently had a need for a mid-sized amount of real-world data, which I required for testing purposes on low-end hardware (testing and demonstrating some of the new functionality of SQL Server 2005). I wanted something that wasn't confidential, which excluded the easy choice of using business data, and I refrain from using artificial data..." more

A Trick to Register Good Generic Domain Names

A good domain name can be difficult to find... in particular when the domain name extension is highly demanded. It is what is happening with the .CLUB new gTLD. Should your Registrar tell you that the desired domain name is not available, it is not necessarily true. Anybody involved in launching a website has to go through a search for a domain name, and most of the time, it begins with the following question: "is the .com available?". Most of the time the answer is: "no it is not".  more

No Spectrum Shortage, Just an Allocation Problem

As a new study from Citi Investment Research & Analysis make clear, the US does not have a spectrum shortage. We've just allowed a relatively small number of carriers to control the spectrum. ... Perhaps if we had an effective "use it or lose it" policy in place, or a heavy tax on unused spectrum a more vibrant market for this spectrum would emerge. more

World Economic Forum Davos 2022: War in Ukraine, Metaverse und Splinternet

The war in Ukraine, Metaverse and Splinternet were among the most discussed items during the recent World Economic Forum (WEF) in Davos. The topic of cyber security was primarily about the role of cyberattacks in the Ukraine war. Cyber is not the focus of day-to-day public war reporting but is an integral part of warfare on both sides. This applies above all to the use of "social media." 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

IoT Devices Will Never Be Secure - Enter the Programmable Networks

Harvard Business Review just ran an interesting article on the information security aspects of Internet of Things (IoT). Based on the storyline, the smart city initiatives are doomed to fail unless the security of the IoT devices and the systems will be improved. While security of the digital society is obviously a key concern, I am not entirely convinced that relying on the security of individual devices and systems is the best course of action. more

Report on Survey of Domain Registration Services

Numerous competitive registrars offer diverse domain registration services to individuals, companies, and organizations. This study attempts to index and analyze their service offerings, facilitating analysis by other researchers and in preparation for additional analysis by the author.  more

ACPA Applies to Noncommercial Use of Domain Name

A recent decision by the Ninth Circuit confirms that "commercial use" by the defendant is required for a Lanham Act trademark or dilution claim, but is not required in a cybersquatting claim under the Anticybersquatting Consumer Protection Act (ACPA). Michael Kremer, a dissatisfied hair transplant patient, used the domain name www.BosleyMedical.com as a site critical to the Bosley Medical Institute, a hair transplant clinic. Bosley sued. The district court entered summary judgment for Kremer on the grounds that his conduct was not commercial... more

Mooning the Porn Stars

Steve DelBianco did a great job of discussing the rocky relationship between ICANN's Government Advisory Committee (GAC) and the Board of Directors, in his piece entitled ".XXX Exposes the Naked Truth for ICANN". I've been keeping an eye on the adult industry press to see what their reaction is to the .XXX debacle. But before we start, let's get something out of the way. more

The Highest Threat TLDs - Part 2

In the first article of this two-part blog series, we looked at how frequently domains were used by bad actors for phishing activity across individual top-level domains (TLDs) or domain extensions, using data from CSC's Fraud Protection services, powered by our DomainSecSM platform. In this second article, we analyze multiple datasets to determine the highest-threat TLDs, based on the frequency with which the domains are used egregiously for a range of cybercrimes. more

IDN Evolution Discussed at ICANN Cartagena

Internationalized domain names (IDNs) have been available to Internet users for many years, but this year the first fully non-Latin IDN domains have become enabled by ICANN and country-code top-level domain registries. The recent success of the launch of Russia's .?? (.rf) ccTLD shows that there is an enormous demand for domain names in Internet users' native languages. more

The Highest Threat TLDs - Part 1

A domain name consists of two main elements: the second-level domain name to the left of the dot - often consisting of a brand name or relevant keywords - and the domain extension or top-level domain (TLD) to the right of the dot. Domain names form the key elements of the readable web addresses allowing users to access pages on the internet and also allowing the construction of email addresses. more

Designing Secure Networks with Cisco Technology, Part 4

In this multipart series I will be presenting some of the leading industry-standard best practices for enterprise network security using Cisco technologies... In Part 3 of this series I began to discuss Cisco technologies as a standard for enterprise data security. In this article we take a look at how Cisco firewall and packet filtering technologies can be used at the network perimeter to enhance enterprise security. more

The Ugly End of the Phone Network

I was a little early. "By the end of President Obama's first term, there won't be any more copper landlines left in the country, I blogged just after Obama had been elected. Before that I'd prophesized the end of POTS (Plain Old Telephone Service) by 2010. Nevertheless, the end is nigh. And it's gonna be ugly without some planning. more
