I've been privately talking about the theoretical dangers of HTTPS hacking with the developers of a major web browser since 2006 and earlier last month, I published my warnings about HTTPS web hacking along with a proposed solution. A week later, Google partially implemented some of my recommendations in an early Alpha version of their Chrome 2.0 browser... This week at the Black Hat security conference in Washington DC, Moxie Marlinspike released a tool called SSL Strip... more
The UN's WSIS Prepcomm in Geneva has ended on a divided note. The US Government's Ambassador Gross pre-announced war-cry "The United Nations will not be in charge of the Internet. Period." had been met by a nearly unanimous global response from nations for some sort of government control of the Internet on a multilateral basis. A raft of proposals to alter the current situation are on the table -- most of them fairly benign, but none supportive of the indefinite continuance of unilateral US control of the root zone authorisation. more
The OECD held a "high-level" meeting in June 2011 that was intended to build upon the OECD Ministerial on The Future of the Internet Economy held in Seoul, Korea in June 2008. I was invited to attend this meeting as part of the delegation from the Internet Technical Advisory Committee (ITAC), and here I'd like to share my impressions of this meeting. This 2 day meeting, "The Internet Economy: Generating Innovation and Growth", had the objective of exploring a number of current issues in the public policy space... more
As facts unfold, and the NTIA's decision to take away our privacy comes to light, it is interesting to see the NTIA struggling to explain its decision. Keep in mind that an "as yet to be identified" bureaucrat made this decision to take away your privacy, did it without notice, and without holding hearings. Those affected were not given an opportunity to explain how the loss of privacy would negatively affect them. Quite simply, this is NOT how our government is supposed to work. We should be outraged... more
It's late in the new gTLD day and the program looks to be inching ever closer to the finish line. Yet last minute hiccups seem to be a recurring theme for this ambitious project to expand the Internet namespace far beyond the 300 odd active TLDs in existence today (counting generics and country codes). A drive for growth which is already underway, with 63 gTLD contracts now signed as of mid September... But will those users find themselves at greater risk because of this namespace expansion? That's what several parties have been asking in recent months. more
In a discussion about a recent denial of service attack against Twitter, someone asked, "Some class of suppliers must be making money off of the weaknesses. Anybody out there have a prescription for the cure?" Sure, but you're not going to like it. The Internet was originally a walled garden, where its operators knew who all the users were and could eject anyone who misbehaved... more
The Domain Name System (DNS) offers ways to significantly strengthen the security of Internet applications via a new protocol called the DNS-based Authentication of Named Entities (DANE). One problem it helps to solve is how to easily find keys for end users and systems in a secure and scalable manner. It can also help to address well-known vulnerabilities in the public Certification Authority (CA) model. Applications today need to trust a large number of global CAs. more
On Wednesday September 29th at 1PM there will be a meeting in the Old Executive Building in Washington D.C. with Registries and domain Registrars to discuss illegal Internet sales of prescription drugs. ICANN was originally invited but declined because citing "inappropriateness" . One "U.S." Registrar who definitely will not be in attendance is OnlineNIC more
A group of leading domain name registries and registrars have joined forces in the fight against abuse in the Domain Name System (DNS), by developing a "Framework to Address Abuse." Each contributing company has shared its expertise and experience mitigating abusive practices with the goal of submitting the resulting Framework as a foundational document for further discussion in the multistakeholder community. more
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
In a follow up to Microsoft's Strider URL Tracer tool released a few months ago, SecurityFocus is running an article which takes a closer look at how Microsoft's free Strider URL Tracer with Typo-Patrol is aimed at fighting typo-squatters and domain parking abuse. From the article: "In most cases, the typo domain is not even selling a product or service itself. The typo domain makes its money from syndicated advertising such as Google's AdSense program. The typo-squatter simply parks the domain and the only content on the site ends up being the ads served from a syndicated advertising program..." more
I have previously pointed out the shortcomings of good and user friendly support for DNSSEC in Microsoft's Server 2008 R2. During the period just after I wrote the post, I had a dialogue with Microsoft, but during the last months there has been no word at all. The reason I bring this up again is that more and more Top Level Domains (TLDs) now enable DNSSEC and also the fact that within six months the root will be signed. more
Internet Protocol addresses fill two unique roles. They are both identifiers and locators. They both tell us which interface is which (identity) and tell us how to find that interface (location), through routing. In the last myth, about network scanning, we focused mainly on threats to IPv6 addresses as locators. That is, how to locate IPv6 nodes for exploitation. Today's myth also deals with IPv6 addresses as identifiers. more
On May 29, I attended an AEI event on "International economics and securing next-generation 5G wireless networks," with Ambassador Robert Strayer, who heads the U.S. State Department's CIP team. But the focus of the talk was not really on 5G security, international trade or 5G development. In fact, there was no constructive agenda at all. The talk was an extended attack on China and the Chinese-based telecommunications vendor Huawei – another episode in an ongoing U.S. government campaign to shut Huawei and other Chinese firms out of the U.S. market, and to convince every other country in the world to do the same. more
Without commenting on the particulars as they relate to Goodmail -- especially since I am on the advisory board for Habeas, a competitor -- let me note that public discussion is largely missing the nature of the current Internet mail realities and the nature of the ways we can deal with them. There are two articles in the current issue of the Internet Protocol Journal, of which I wrote one, that provide some useful background about this reality. Simply put, Internet mail needs to sustain spontaneous communications... more
