What is ‘Pharming’ and Should You Be Worried?

The sky is falling! The sky is falling! ...or is it? What is this thing called "pharming"? Put simply, it's redirection of web traffic, so that the server you think you're talking to actually belongs to a criminal. For example: you think you're talking to www.examplebank.com because it says so in the browser's address bar, but actually you're connected to www.mafia-R-us.ru. This can happen in three main ways: 1. DNS Hijack: a social engineering attack on the Internet infrastructure... more

Internet Governance: Analogue Solutions to Digital Problems

This is an overview of the booklet, "Internet Governance: Issues, Actors and Divides," recently published by DiploFoundation and the Global Knowledge Partnership. "Internet Governance is not a simple subject. Although it deals with a major symbol of the DIGITAL world, it cannot be handled with a digital - binary logic of true/false and good/bad. Instead, the subject's many subtleties and shades of meaning and perception require an ANALOGUE approach, covering a continuum of options and compromises." Update: This article was reposted with additional information and a new title. more

History of SMTP

The following excerpt is from the Free Software Magazine, March 2005 Issue, written by Kirk Strauser. To read the entire article, you may download the magazine here [PDF]. Also thanks to Yakov Shafranovich for making us aware of this publication. "Spam has existed since at least 1978, when an eager DEC sales representative sent an announcement of a product demonstration to a couple hundred recipients. The resulting outcry was sufficient to dissuade most users from repeating the experiment. This changed in the late 1990s: millions of individuals discovered the internet and signed up for inexpensive personal accounts and advertisers found a large and willing audience in this new medium." more

CENTR Statement on IDN Homograph Attacks

Recently a proof of concept attack was announced on the Internet that demonstrated how a web address could be constructed that looked in some web browsers identical to that of a well known website. This technique could be used to trick a user into going to a website that they did not plan on visiting, and possibly provide sensitive information to a third party. As a result of this demonstration, there has been a number of voices calling for web browsers to disable or remove support for IDNs by default. ...CENTR, a group of many of the world's domain registries - representing over 98% of domain registrations worldwide - believes such strong reactions are heavily detrimental... more

10 Things Google Could Do as a Domain Name Registrar

In the absence of any formal announcements, news of Google being accredited by ICANN as a domain name registrar, spread fast in the media today after it was first reported by Bret Fausett on Lextext -- see Google is a Registrar. The company has since mentioned that "Google became a domain name registrar to learn more about the Internet's domain name system," and that it has no plans to sell any domain names at the moment. However, speculations on what Google could do as an accredited registrar are far and wide. Here are ten, listed in no particular order... more

IDN Spoofing Solutions With Balance

Last week's tizzy about IDN (Internationalized Domain Name) spoofing was an interesting exercise in watching how people react to the unknown. The nearly-universal response to the problem that had been described in detail many years ago was "turn off IDNs" instead of "assume that the people who created IDNs knew about this, so let's do some research." The following is based on my thoughts this week. For those of you who are not familiar with my earlier work, I'm one of the authors of the IDN standards... more

Closer Look at Domain Name Transfer Policy and the Hijacking of Panix.com

Given the recent panix.com hijacking, I will give an outline of the current ICANN transfers process for gtlds. In the case of panix.com, evidence so far indicates that a third party that holds an account with a reseller of Melbourne IT, fraudulently initiated the transfer. The third party appears to have used stolen credit cards to establish this account and pay for the transfer. That reseller is analyzing its logs and cooperating with law enforcement. more

Internet to ITU: Stay Away from My Network

An ITU document entitled "Beyond Internet Governance" crossed my desk earlier this week. Given that I had absolutely nothing better to do, I decided to give it a read. The audacity of the ITU Secretariat is nothing less than shocking. It has been a long while since I read such a self-serving, narrow-minded and inaccurate document. The backbone of the ITU's contention rests on the premise that something called the Next Generation Network and the contention that this network will act as one big bug fix for all the problems created by current inter-networking technology. more

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

Survey Predicts Attacks on the Network Infrastructure Within 10 Years

Pew Internet Project has released a report called "The Future of the Internet" based on a recently conducted survey where 1,286 internet experts are said to have looked at the future impact of the internet and assessed predictions about how technology and society will unfold. The following is and excerpt from the report predicting at least one devastating attack will occur in the next 10 years on the networked information infrastructure or the United States power grid. more

OMB Focuses On Cybersecurity

Ensuring federal cybersecurity is essential to protecting national security. According to some media reports, recommendations have been made to the Bush Administration to "create a distinct administrative cybersecurity position within the Homeland Security Department to oversee progress in the federal government and act as a liaison with private industry." However, before new bureaucracy is created, it is important to recognize the practical cybersecurity policies and projects that are already being undertaken by the Administration. more

Person to Person Security and Privacy Infringement

IT security strategies invariably focus on maintaining impenetrable fortresses around computers and network systems. Firewalls, virtual private networks and anti-virus programs are the tools IT engineers use to create their digital security. Sophisticated defense systems can be very effective at keeping the obvious attackers at bay, yet they often create a false sense of security because the real attacks, the kind that inflict irreparable damage on a system or network, avoid the obvious routes into the secure fortress. more

Internet Management and National Security: Time for a Federal Action Plan

Former CIA Director George Tenet recently gave a speech highlighting the need for federal action on internet management in order to protect national security. As reported by the online edition of Government Executive, Mr. Tenet explained that, "greater government regulation of the Internet and telecommunications networks is needed in order to guard against terrorist attacks." more

Cornucopia: A Radically Different Approach to TLDs

Much of the discussion about proposed TLDs centres around domain names as a form of classification: ".mobi" for mobile device content, ".kids" for child-safe content, language codes for language-specific content, ".museum" for museum-related entities, and so on. Notoriously little activity has been forthcoming in actually implementing these proposals, and the select few that have been allowed out into the world are, shall we say, a tad arbitrary. I'd like to engage in a little thought experiment where we abandon the "few TLDs with carefully chosen meanings" paradigm, and instead consider the benefits of a cornucopia of completely meaningless TLDs. more

Adult-Related TLDs Considered Dangerous

In an RFC prepared by Donald E. Eastlake 3rd and Declan McCullagh, an analysis is offered for proposals to mandate the use of a special top level name or an IP address bit to flag "adult" or "unsafe" material or the like. This document explains why these ideas are ill considered from legal, philosophical, and technical points of view: "Besides technical impossibility, such a mandate would be an illegal forcing of speech in some jurisdictions, as well as cause severe linguistic problems for domain or other character string names." more
