Routing Attacks on Internet Services

This post was co-authored by Yixin Sun, Annie Edmundson, Henry Birge-Lee, Jennifer Rexford, and Prateek Mittal. In this post, we discuss a recent thread of research that highlights the insecurity of Internet services due to the underlying insecurity of Internet routing. We hope that this thread facilitates important dialog in the networking, security, and Internet policy communities to drive change and adoption of secure mechanisms for Internet routing. more

The 500M Wireless-Only Connections

Around 500M Africans, Indonesians, and Indians are regular Internet users without a landline. Brazil, Indonesia, and Mexico add about 200M more. In total, something like 1B people were wireless-only at the end of Q3 2017. I'm comparing the number of Facebook users (over 250M in India) with the number of landlines (less than 20M in India) for a rough guess at how many are wireless only. In the developed world, 70-90% of all homes have a landline connection... more

Is It Time for a Data Sharing Clearinghouse for Internet Researchers?

Today's Senate hearing with Facebook's Mark Zuckerberg will start a long discussion on data collection and privacy from Internet companies. Although the spotlight is currently on Facebook, we shouldn't forget that the picture is broader: companies from device manufacturers to ISPs collect network traffic and use it for a variety of purposes. more

The Color of the Net Has Changed

About 65% of 1.5B Internet "connections" are in the Global South, led by the BRICS. The actual number of users is probably twice that. Three quarters are not native English speakers. China has three times as many as the United States. India has more Facebook users than the United States. Vietnam has the fastest growth. See some figures below for why I'm confident Indonesia has more than 100M wireless only. more

Today’s Internet: More BRICS Than Westerners

Something over 55% of landline broadband users are in the "Global South," about 500M. The South is about 65% if you include "wireless-only" many of which are 4G LTE at ten megabits or more. The gap is widening rapidly and will increase by well over 70M in 2018. Six large developing countries are growing 5% or more in the last year, compared to only one in the developed world. China is adding ~30M more each year. Most developed countries are between 75% and 95% connected. That leaves little room for growth. more

GDPR and WHOIS - Winners and Losers

I think we are all hoping that when ICANN meets with the DPAs (Digital Protection Authorities) a clear path forward will be illuminated. We are all hoping that the DPAs will provide definitive guidance regarding ICANN's interim model and that some special allowance will be made so that registrars and registries are provided with additional time to implement a GDPR-compliant WHOIS solution. more

Parsing Predatory and Parasitical from Innocent and Good Faith Domain Name Registrants

When the World Intellectual Property Organization began deliberating in 1998 and 1999 about creating an arbitral regime that the Internet Corporation for Assigned Names and Numbers transformed into the Uniform Domain Name Dispute Resolution Policy the curse words of choice were "predators" and "parasites" to describe cybersquatters. (In an early UDRP decision a Respondent who had also featured as a defendant in a trademark case asserted he had "just as much right to own the Domain Names [with typographic variations of the mark] as the person who owns the correct spelling of [the mark]" more

A 5G Community Network Strategy for Cuba (and Other Developing Nations)

In a previous post, I suggested that Cuba might be able to leap over 4G to 5G wireless infrastructure using satellite and terrestrial networks for backhaul. While that would require political and policy change, it would be a good fit with Cuban culture and skills. Before talking about Cuba, let me say a bit about wireless generations. Each mobile technology generation used new technology and enabled new applications. more

We Need to Disconnect from Facebook Right Now

The smartphone has effectively transformed us into cyborgs, we have in our hands a highly efficient computing device equipped with a photo and video camera, microphone, GPS, accelerometer, gyroscope, magnetometer, light and proximity sensors, as well as other features that allow creation of increasingly useful, impressive and addictive applications. more

Facebook vs. Domain Names: Lessons from Cambridge Analytica

The current revelations about Cambridge Analytica's use of Facebook data illustrate an important drawback to using a Facebook account as your business' online presence: Facebook knows and sells your customers! Millions of companies - especially small companies and start-ups - rely on a Facebook account for their online presence. On the surface, it seems like a great idea... more

ICANN IPC & BC to Host Cross-Community Call on Accreditation/Access Model for Non-Public WHOIS Data

The ICANN Intellectual Property Constituency (IPC) and Business Constituency (BC) will be hosting a community-wide discussion regarding the proposed accreditation and access model for non-public WHOIS data, which was first circulated to the community during ICANN 61. The discussion will take place via ICANN-supported remote participation and/or audio bridge this Friday, April 6, 2018, from 1400-1600 UTC. more

Oblivious DNS: Plugging the Internet’s Biggest Privacy Hole

The recent news that Mozilla and Cloudflare are deploying their own DNS recursive resolver has once again raised hopes that users will enjoy improved privacy, since they can send DNS traffic encrypted to Cloudflare, rather than to their ISP. In this post, we explain why this approach only moves your private data from the ISP to (yet another) third party. You might trust that third party more than your ISP, but you still have to trust them. In this post, we present an alternative design -- Oblivious DNS -- that prevents you from having to make that choice at all. more

ICANN Cannot Expect the DPAs to Re-Design WHOIS, but Asking for a Reprieve Makes Sense

We are on the brink of the most serious threat to the open and public Internet for decades. ICANN, under pressure from domain name registrars and EU data protection authorities, has proposed an "interim" plan that will hide critical information in WHOIS. Security, threat intelligence, and anti-abuse professionals rely on WHOIS to track down bad guys and keep the Internet as safe and secure as possible. more

Security, Standards, and IoT: Will Connected Devices Flourish Under Prescriptive Regimes?

Security for Internet-connected devices, the "Internet of Things" (IoT), is critically important. Now, more than ever, it is top of mind for device manufacturers, network operators, consumer advocates, lawmakers, and government regulators -- domestically and internationally. In the face of recent attacks, government authorities and consumer advocates have proposed legislation, frameworks, certifications, and labeling schemes. more

European Commission Killing Off Thousands of EU Domains Due to Brexit

After the Brexit vote, I wrote that there could be an impact on EU registrants based in the UK. Over the past year, the UK government has been engaged in negotiations with the EU to navigate the application of Article 50 and the UK's exit from the European Union. While there has been a lot of focus on issues like the customs union and the border between Ireland and Northern Ireland, the eventual departure of the UK from the EU will have a tangible impact on the European digital economy. more
