She Gave Me a Fake Phone Number!

The Intellectual Property Constituency, meeting at the ICANN conference in Vancouver, was interested in increasing ICANN's budget not because they thought they deserved it, but because they wanted ICANN to actually enforce the rules on the books about fake registrations. Now there's some evidence about how prevalent that is. If there's any surprise here, it's that the numbers are so low. more

The WSIS Deal

There is considerable coverage this morning (or this evening in Tunis) on the last minute WSIS deal struck yesterday. The gist of the coverage rightly reports that the U.S. emerged with the compromise they were looking for as the delegates agreed to retain ICANN and the ultimate U.S. control that comes with it (note that there is a lot in the WSIS statement that may ultimately prove important but that is outside the Internet governance issue including the attention paid to cybercrime, spam, data protection, and e-commerce). This outcome begs the questions -- what happened? And, given the obvious global split leading up to Tunis, what changed to facilitate this deal? more

Welcome to the Root, .MOBI

mTLD's .mobi entered the root zone on Tuesday, quietly contrasted amidst all of the recent ICANN/VeriSign announcements. The .mobi mTLD is a Dublin, Ireland based joint venture between the Nokia Corporation, Vodafone Group Services Limited, and Microsoft. The .mobi domain was granted to service a sponsored community, consisting of: Individual and business consumers of mobile devices, services and applications; Content and service providers; Mobile operators; Mobile device manufacturers and vendors; IT technology and software vendors who serve the mobile community, and there are numerous benefits of .mobi to this community. more

So You Think You’re Safe from DNS Cache Poisoning?

Everyone is probably well aware of the Kashpureff-style DNS cache- poisoning exploit (I'll call this "classic cache poisoning"). For reference, see the original US-CERT advisory prompted by this exploit. Vendors patched their code to appropriately scrub (validate) responses so that caches could not be poisoned. For the next 7-8 years, we didn't hear much about cache poisoning. However, there was still a vulnerability lurking in the code, directly related to cache poisoning. ...On April 7, 2005, the SANS ISC (not to be confused with Internet Systems Consortium) posted an update detailing how Microsoft Windows DNS servers were still being poisoned, even though the "Secure cache against pollution" option was set. The SANS ISC found that Windows DNS servers using BIND4 and BIND8 servers as forwarders were being poisoned. But how could this be? more

There Is No “Spam Problem”

This month I thought I could feel smug, deploying Postfix, with greylisting (Postgrey), and the Spamhaus block list (SBL-XBL) has reduced the volume of unsolicited bulk commercial email one of our servers was delivering to our clients by 98.99%. Alas greylisting is a flawed remedy, it merely requires the spambots to act more like email servers and it will fail, and eventually they will... more

Phishing: An Interesting Twist on a Common Scam

After Two Security Assessments I Must Be Secure, Right? Imagine you are the CIO of a national financial institution and you've recently deployed a state of the art online transaction service for your customers. To make sure your company's network perimeter is secure, you executed two external security assessments and penetration tests. When the final report came in, your company was given a clean bill of health. At first, you felt relieved, and confident in your security measures. Shortly thereafter, your relief turned to concern. ...Given you're skepticism, you decide to get one more opinion. ...And the results were less than pleasing. more

More on Story Behind .ASIA

James Seng, my good colleague in APEET, said: "...Chiao called .ASIA 'more or less like a joint venture among APxx organizations'. I say nonsense!" When I say more or less, I mean more or less... On this .ASIA entry, I've intended to use the language carefully at this moment 'cos I know someone will be watching... more

Story Behind .ASIA

After releasing .travel and .jobs (hey, steve.jobs up for bidding!), ICANN said they will look at .xxx and .asia next. (via Chiao) "Vint Cerf: ...of those, we have had fairly extensive discussion about .asia and .xxx. We continue to evaluate those. The others will be attended to as we can get to them. But i want to say for the record that we will attempt within the next 30 days to come to a conclusion one way or the other about .asia and .xxx so these will be on a board call sometime within that period." Chiao called .ASIA "more or less like a joint venture among APxx organizations". I say nonsense! Don't let appearance fool you. 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

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

.NET Bid Contenders

Yesterday was the deadline for the submissions of responses to the .NET re-bid RFP. As of my last count, there are five companies that I am aware of that submitted proposals for the .NET rebid. Three of these were quite publicly announced, Afilias, Denic, and Verisign. The other two bidders are Multi-Stakeholder groups. Sentan and Core++. Sentan appears to be a Joint Venture between .jp and Neulevel, and Core++ is ISC, Telfonica, and .br, with participation from Core, Nida (.kr), and .zaDNA (.za). more

Hijacking of Panix.com: A Call for An Emergency Rollback Procedure

There's a thread on NANOG to the effect that Panix, the oldest commercial Internet provider in New York, had its domain name 'panix.com' hijacked from Dotster over to MelbourneIT and it has pretty well taken panix.com and its customers offline. Looks like this may be among the first high-profile unauthorized transfer under the new transfer policy. It begs the question, despite the existence of the dispute policy under the new system, what provisions should there be for a situation like this where every hour causes untold damage to the party in question... more

An Open Letter to NTIA, ICANN, and IANA

I am writing this note in order to express my concern about an impending change in the root of the Domain Name System (DNS) and two of the largest Top Level Domains (TLDs). I am concerned that there is a risk of disruption to the net that has not been adequately evaluated and I am concerned that this change is being deployed without adequate monitoring or safeguards. more

Sender ID: A Tale of Open Standards and Corporate Greed? - Part II

While everything seemed fine and various participants in these discussions were celebrating the merger of these proposals into one, as well as the support of Microsoft in this endeavor, there was an elephant in the room so to speak, and a rather large one at that. When the original Caller-ID proposal was published, a patent license came along with it. Microsoft indicated that they were planning on filing patents on Caller-ID or some of its aspects, and offered a royalty-free license for the use of their intellectual property. There was some talk about the incompatibility of the license with open source software, including comments from Eben Moglen of FSF and Richard Stallman, but Microsoft employees assured the MARID WG that the licensing issue would be resolved in time for the San Diego meeting. Except that it wasn't.  more

What’s Wrong With Spam Prosecutions

Spam these days is more than an annoyance -- it increasingly carries malware payloads that can do serious damage to your PC, steal your identity, or turn your PC into a zombie that carries out denial of service attacks. So anything that law enforcement can do to fight spam should be a good thing, right? Well, not quite, as I'll explain. more
