Vint Cerf Caught Off Guard, Nevertheless Says What Needs to Be Said About Our Misguided Policy

This morning's mail brought news of a 3 minute 45 second video clip of very candid and very outstanding remarks from Vint Cerf. Vint says very clearly what needs to be said and what needs to be grasped and acted on by the new president and congress next year... My observation is that in my opinion it is not the lighting that is unusual but rather the camera angle. It looks like interviewer is seated with his camera pointed up. The camera is looking at Vint's chin. Consequently I sent Vint an email: "you knew you were being recorded - surely? I hope: in any case the good deed is done... thank you sir." Vint replied with permission to quote... more

Study Finds 75% of Malicious Websites from Legitimate, Trusted Sources

New report released today finds 75 percent of malicious websites are from legitimate, trusted sources with "Good" reputation scores. According to the report, 60 percent of the top 100 most popular websites either hosted malicious content or contained a masked redirect to lure unsuspecting victims from legitimate sites to malicious sites. more

No Fines for Comcast

Note: this is an update on my earlier story, which incorrectly said that the AP reported that Chairman Martin was seeking to impose "fines" on Comcast. In fact, the story used the word "punish" rather than "fine," and a headline writer at the New York Times added "penalty" to it "F.C.C. Chairman Favors Penalty on Comcast" (I won't quote the story because I'm a blogger and the AP is the AP, so click through.) Much of the initial reaction to the story was obviously colored by the headline. more

Not a Guessing Game

On Tuesday July 8, CERT/CC published advisory #800113 referring to a DNS cache poisoning vulnerability discovered by Dan Kaminsky that will be fully disclosed on August 7 at the Black Hat conference. While the long term fix for this attack and all attacks like it is Secure DNS, we know we can't get the root zone signed, or the .COM zone signed, or the registrar / registry system to carry zone keys, soon enough. So, as a temporary workaround, the affected vendors are recommending that Dan Bernstein's UDP port randomization technique be universally deployed. Reactions have been mixed, but overall, negative. As the coordinator of the combined vendor response, I've heard plenty of complaints, and I've watched as Dan Kaminsky has been called an idiot for how he managed the disclosure. Let me try to respond a little here, without verging into taking any of this personally... more

Shouting ‘Bug’ on a Crowded Internet…

In the last few weeks we've seen two very different approaches to the full disclosure of security flaws in large-scale computer systems. Problems in the domain name system have been kept quiet long enough for vendors to find and fix their software, while details of how to hack Transport for London's Oyster card will soon be available to anyone with a laptop computer and a desire to break the law. These two cases highlight a major problem facing the computing industry, one that goes back many years and is still far from being unresolved. Given that there are inevitably bugs, flaws and unexpected interactions in complex systems, how much information about them should be made public by researchers when the details could be helpful to criminals or malicious hackers? more

Jeremy Jaynes Gets One More Chance

n 2004 Jaynes became the country's first convicted spam felon under the Virginia anti-spam law. He's been appealing his conviction ever since, most recently losing an appeal to the Virginia Supreme Court by a 4-3 decision in February. As I discussed in more detail at the time the key questions were a) whether the Virginia law had First Amendment problems and b) whether Jaynes had standing to challenge it. The court answered No to b), thereby avoiding the need to answer a), the dissent answered Yes to both. more

The Patent That Justifies Microsoft’s Interest in Yahoo!

I've watched coverage of Microsoft's bid for Yahoo! and the related maneuvering between Google and Yahoo!. The explanations are not very convincing. Microsoft doesn't need Yahoo's search technology or their morale-impacted work force. Yahoo's search market share continues to decline and there's little of strategic relevance in the rest of their business. What's the attraction? more

Note to John McCain: Technology Matters

One would think that, in 2008, the significance of the Internet and information technology would be universally acknowledged. That makes the recent news from the Presidential campaign a bit shocking. After ignoring technology issues for the past year, John McCain is poised to announce his great insight: tech policy isn't worthy of attention from the President of the United States. This is what I draw from the announcement that former FCC Chairman Michael Powell is drafting a technology plan for McCain, to be released shortly... What concerns me most is what the McCain plan apparently leaves out... more

Is It Time to Create a Market for IPv4 Addresses?

It's fascinating to watch the Internet technical community grapple with policy economics as they face the problems creating by the growing scarcity of IPv4 addresses. The Internet Governance Project (IGP) is analyzing the innovative policies that ARIN, RIPE and APNIC are considering as a response to the depletion of IPv4 addresses. more

Anti-Phishing and Hong Kong

Planning for a short trip to Hong Kong tomorrow reminded me of Jonathan Shea, something I wanted to blog about but was waiting for the hype around the new generic Top-Level Domains (TLDs) to cool down. Jonathan Shea is an old friend who is in-charge of ".hk". I had the pleasure to catch up with him in Paris ICANN meeting. Before Jonathan, let me talk about something related that happened in Paris. At the Cross Constituency Meeting, there was a presentation by the Anti-Phishing Working Group (APWG). In summary, they were proposing working with registries to take down domain names that are suspected to be involved in phishing. more

Consequences of Opt-in Better Than Best Efforts Internet Routing

While attending the International Telecommunications Society's 17th bi-annual conference I attended yet another network neutrality session. Economists predominated at this conference and their collective read on network neutrality emphasizes the need for ISPs to "extract value" from content providers primarily by converting zero cost peering with ISPs into specific payments from individual content sources. I have no problem with offers of non-neutral, "better than best efforts" routing options to content providers who voluntarily opt in, particularly if the offer is made transparently and anyone can opt in. What troubles me is the impact of opt-in on content providers that opt out... more

FCC and Comcast: Reasonably Vague

So, the FCC will recommend that Comcast be "punished" or receive "sanctions" for its peer-to-peer throttling practice. And the network neutrality debate goes on, as does its ambiguities and vagueness. Even if you hate Comcast and agree with the net neutrality argument and the FCC's decision, one thing Comcast is correct in saying is that "reasonable network management" specified by the FCC in network neutrality policy set in 2005 is vague. Actually, the term "network management" by itself is broad before you even try to interpret what is meant by "reasonable", and it is not exactly correct in its application here... more

Why New TLDs Don’t Matter

Lost amid the furor about ICANN's rule change that may (or may not) lead to a flood of TLDs is the uncomfortable fact that almost without exception, the new TLDs created since 2000 have been utter failures. Other than perhaps .cat and .mobi, they've missed their estimates of the number of registrations by orders of magnitude, and they haven't gotten mindshare in the target community. So what went wrong? more

Advertising Pays for a Lot of Things… What Happens When the Ad Budget Dries Up in a Recession?

Doing some research on the effects of the Great Depression in the 1930s, I started wondering what happened to advertising during that period. Although I haven't turned up any detailed studies, I took a look at the various archives of advertising that allow Internet access to their exhibits, and noted the general move to less expensive, more localized advertising, and fewer adverts for more expensive goods. It made me wonder what will happen to online advertising if the current credit crunch starts to drive a worldwide recession... more

The SocialDNS Project… and Why DNS is Not the Phone Book of the Internet

In this article I will explain the motivations behind the SocialDNS Project. I will justify why the DNS system is NOT the phone book of the Internet. More concretely, DNS is not a public directory nor enables search mechanisms over meta-information related to domains. In this line, I will present the advantages of SocialDNS, a naming and directory system that aims to become the phone book of the Web. SocialDNS is NOT another alternative DNS root nor aims to replace the current DNS for resolving domain names. It complements the existing DNS to offer advanced services that are beyond the scope of the existing infrastructure for Web settings. more
