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

A decade of collaboration and inspiration! Thank you to the incredible community that has fueled this journey! more

DNSSEC Baby Steps Reported at ICANN 41

The Internet is slowly beginning to adopt the new DNSSEC domain names standard, but significant challenges remain. That was the main takeaway from a four-hour workshop on the technology held during the recent ICANN 41 public meeting in Singapore, which heard from many domain registries, registrars and other infrastructure providers. more

What’s Behind the Secure DNS Controversy and What Should You Do About It?

Anyone that has attended a meeting of the Internet Engineering Task Force (IETF) will know that the somewhat dry topic of internet protocols is often the source of passionate disagreement. But rarely does that debate extend beyond the confines of internet engineers. That has not been the case with a new protocol which aims to make the Internet's underlying domain name system more secure by default. more

OpenDNS Adopts Proposed DNS Security Solution: DNSCurve

For more than 15 years, the IETF has been working on DNSSEC, a set of extensions to apply digital signatures to DNS. Millions of dollars in government grants and several reboots from scratch later, DNSSEC is just starting to see real world testing. And that testing is minimal -- only about 400 of the more than 85,000,000 .com domains support DNSSEC, fewer than 20% of US government agencies met their mandated December 31, 2009 deadline for DNSSEC deployment, and only two of the thirteen root zone name servers is testing with even dummy DNSSEC data. more

2012 Global Phishing Trends: Uptime Down, Numbers Up

Despite security advances over the past year, including the increased deployment of DNSSEC, pirates continue to wreak havoc on the Internet. But before you decide that Internet security innovations are futile, consider this: online criminals are just like burglars in the physical world; they don't take new ways of blocking their best efforts lying down. They come up with new and, in some cases, stronger plans of attack. more

DNSSEC Adds Value?

The recent news that .uk, .arpa and .org may sign their zones sometime this year is indeed good news. Each domain is highly significant... As the DNSSEC registry infrastructure moves inexorably forward -- primarily driven by top level pressure and considerations of National Interest -- it now behoves us to clearly articulate the benefits of DNSSEC to domain owners and registrars. In particular I want to focus on the vast majority of us to whom cold, hard cash is important and parting with it requires as a minimum tangible benefits or, in extreme cases, surgical intervention. more

Beyond the Top Level: DNSSEC Deployment at ICANN 40

I recently wrote about the encouraging level of DNSSEC adoption among top-level domain name registries, and noted that adoption at the second level and in applications is an important next step for adding more security to the DNS. The root and approximately 20 percent of the top level domains are now signed; it is time for registrars and recursive DNS servers operated by the ISPs to occupy center stage. more

Open DNS Resolvers - Coming to an IP Address Near You!

Three vectors were exploited in the recent DDoS attack against Spamhaus: 1) Amplification of DNS queries through the use of DNSSEC signed data; 2) Spoofed source addresses due to lack of ingress filtering (BCP-38) on originating networks; 3) Utilisation of multiple open DNS resolvers While. 1) is unavoidable simply due to the additional data that DNSSEC produces, and 2) "should" be practised as part of any provider's network configuration, it is 3) that requires "you and I" ensure that systems are adequately configured.  more

Call for Proposals: ICANN 64 DNSSEC Workshop in Kobe, Japan (March 2019)

Will you be at the ICANN 64 meeting in March 2019 in Kobe, Japan? If so (or if you can get to Kobe), would you be interested in speaking about any work you have done (or are doing) with DNSSEC, DANE or other DNS security and privacy technologies? If you are interested, please send a brief (1-2 sentence) description of your proposed presentation before 07 February 2019. more

DNS and the Internet of Things: Opportunities, Risks, and Challenges

The ICANN Security and Stability Advisory Committee (SSAC) has recently published SAC105, a report on the interplay between the DNS and the Internet of Things (IoT). Unlike typical SSAC publications, SAC105 does not provide particular recommendations to the ICANN Board, but instead is informative in nature and intends to trigger and facilitate dialogue in the broader ICANN community. more

Is DNSSEC Worth the Effort?

A blog post has created some attention online through its extremely negative attitude to DNSSEC. Through the years, I have come in contact with many arguments against DNSSEC that suggest that anyone who is critical has not managed to or wanted to familiarize themselves with what DNSSEC is and does. We have received many questions concerning the article, so I feel it's appropriate to respond to the criticism. more

Verisign Provides Open Source Implementation of Merkle Tree Ladder Mode

The quantum computing era is coming, and it will change everything about how the world connects online. While quantum computing will yield tremendous benefits, it will also create new risks, so it's essential that we prepare our critical internet infrastructure for what's to come. That's why we're so pleased to share our latest efforts in this area, including technology that we're making available as an open source implementation to help internet operators worldwide prepare. more

Analysis of 7.5 Trillion DNS Queries Reveals Public Resolvers Dominate the Internet

A recent report by NS1 provides a comprehensive look at global DNS traffic trends. It reveals that public resolvers dominate the internet, accounting for nearly 60% of recursive DNS usage. Telecom giants represent nearly 9%, with Google the clear front-runner at a little over 30%, followed by Amazon Web Services at 16%. more
