Nitol and 3322.org Takedown by Microsoft

Reading this morning's blog from Microsoft about "Operation b70" left me wondering a lot of things. Most analysts within the botnet field are more than familiar with 3322.org - a free dynamic DNS provider based in China known to be unresponsive to abuse notifications and a popular home to domain names used extensively for malicious purposes - and its links to several botnets around the world. more

Internet Society Releases Paper on “What Really Matters About the Internet”

Internet Society has released a paper today highlighting the importance of understanding what is important and unchanging about the Internet. more

No External Attacks Behind GoDaddy’s Major Outage, Says Company

GoDaddy.com has reported today that the Web hosting outage that involved thousands and possibly millions of websites on Monday was due to internal issues and did not involve any attacks by hackers. The outage lasted for about four hours and affected mainly small-business sites. GoDaddy.com hosts more than 5 million websites. more

Researchers Detail Faster Methods to Defeat Botnets Like Conficker and Kraken

Michael Cooney reporting in NetworkWorld: "Security researchers this week will detail a prototype system they say can better detect so-called Domain Name Generation- (DGA) based botnets such as Conficker and Kraken without the usual labor- and time-intensive reverse-engineering required to find and defeat such malware. The detection system, called Pleiades, monitors traffic below the local DNS server and analyzes streams of unsuccessful DNS resolutions..." more

New Top Level Domains Application Metering - Figure It Out ICANN!

Let me begin by saying that I am big supporter of ICANN. But good grief ICANN, why must the ENTIRE new gTLD process be so painful? I could run through a long list of all the delays, missteps and glitches, but why bother? It's almost comical at this point -- although not for 1,930 new gTLD applicants who have been waiting for ICANN to get their act together. First we were led to believe that the batching of applications was necessary due to resourcing constraints, which I personally never understood as the evaluation of applications is being done be third-party consultants. more

How to Evaluate Performance of a DNS Resolver

Ten years ago everyone evaluating DNS solutions was always concerned about performance. Broadband networks were getting faster, providers were serving more users, and web pages and applications increasingly stressed the DNS. Viruses were a factor too as they could rapidly become the straw that broke the camel's back of a large ISP's DNS servers. The last thing a provider needed was a bottleneck, so DNS resolution speed became more and more visible, and performance was everything. more

“Globally, Internet Traffic Passes Through 13 Root Servers” (!)

The Times of India recently interviewed India's Minister of State for Communications and IT, Sachin Pilot, on Internet Governance. Titled "'Internet's governance can't be limited to one geography'", the article started off with an amazing assertion by the minister... While this interview is a fairly standard restatement of the position some Governments (including India) have about governmental control of Internet Governance, it is sadly apparent that the minister unfortunately doesn't appear to understand what the root servers are, or how they work. more

High Performance DNS Needs High Performance Security

There's been a lot of emphasis on DNS performance lately because faster DNS contributes directly to a better user experience. There's an interesting flipside to DNS performance though, higher performance DNS servers may be better targets for cache poisoning attacks. Faster servers give attackers more opportunities to insert fake entries into the DNS - speed can kill (or at least inflict a nasty wound!) so it's important to understand the security implications if you're looking to upgrade DNS performance. more

WCIT Prep Dénoument?

I'm sitting in the Popov Room of the ITU Tower in Geneva, the room is quiet, the atmosphere placid, chairs are empty. The final meeting of the CWG WCIT prep WG has just concluded its work and the chair will be reporting to the Council the results of our work. I find myself strangely calm and looking forward to my next week, to be spent in Prague... Should you choose to read through the documents, and they are lengthy at approximately 375 pages, you might think that a number of the proposals were directed at the Internet. more

A Closer Look at the AIP Internet Draft Proposal

Just in time for ICANN's 44th meeting next week, a new Internet Draft has turned up, purporting to fix the centralization of the DNS. The draft has received some attention, including an article in PC World. It isn't entirely clear what the real purpose of the draft is, but it is hard to credit the notion that it is solving any technical problem. Without examining the reasons why the draft exists, I want to debunk a claim in it. more

ICANN 44 Prague: A Look at the Future

ICANN's 44th public meeting is about to start in a few days with a number of topics on the agenda. Some of them are new, while some of them are ongoing. First off, ICANN will be announcing the new CEO this Friday afternoon in Prague. Whoever it is will be coming to the organisation at a time when it faces a number of significant challenges. While the actual official meeting does not start until Monday morning there will be plenty of meetings on over the weekend as well... So what's on the "menu" for Prague? more

ICANN Receives 67 Unique Applications for Chinese gTLDs

At the press conference held in London on June 13, the Internet Corporation for Assigned Names and Numbers (ICANN) officially announced a list of 1930 applications for the new generic top level domain (gTLD). During the 40 years since the launch of the Internet, there are only 22 gTLDs such as .com. The 1930 applications represent a historical change to the Internet; For the first time, Chinese gTLDs will become available and there are 67 unique applications for Chinese gTLDs. more

Measurement Results from World IPv6 Launch

As announced on RIPE Labs we monitored the behaviour of a number of networks that participated in the World IPv6 Launch on 6 June 2012. For that, we looked at the full list of participating organisations as shown on the ISOC website and chose 50 websites from that list. We looked at 'interesting' sites and at geographic distribution. We also tried to find a good mix of networks that had IPv6 switched on already and those that didn't have IPv6 deployed at the time they registered on the ISOC web site. more

Taking Stock of New gTLDs in the Public Markets

A woman on the radio talks about revolution, though it's already passed. The window is now closed. A snapshot can be taken. A baseline can be set. How have the public markets valued the new gTLD program? And more importantly, how will public markets value it going forward? Until a few months ago, the new gTLD program was arcane policy discussion among a very narrow technical population of the Internet community. more

Google Notifying Half a Million Users Affected By DNSChanger

Google has announced that it has started undertaking an effort to notify roughly half a million people whose computers or home routers are infected with a well-publicized form of malware known as DNSChanger. "After successfully alerting a million users last summer to a different type of malware, we've replicated this method and have started showing warnings via a special message that will appear at the top of the Google search results page for users with affected devices." more
