In my last blog post about Zoom, I noted that the company says "that critics have misunderstood how they do encryption." New research from Citizen Lab show that not only were the critics correct, Zoom's design shows that they're completely ignorant about encryption. When companies roll their own crypto, I expect it to have flaws. I don't expect those flaws to be errors I'd find unacceptable in an introductory undergraduate class, but that's what happened here. more
Zoom - one of the hottest companies on the planet right now, as businesses, schools, and individuals switch to various forms of teleconferencing due to the pandemic - has come in for much criticism due to assorted security and privacy flaws. Some of the problems are real but easily fixable, some are due to a mismatch between what Zoom was intended for and how it's being used now - and some are worrisome. more
The video-conferencing company Zoom is facing a class-action suit filed on Tuesday accusing it of overstating its privacy standards and failing to disclose that its service was not end-to-end encrypted. more
As widely reported, and not surprising, the internet is swimming in COVID-19 online scams. Criminals, accustomed to rapidly grabbing online territory during times of crisis and profiting from public fear, are working overtime in the face of the coronavirus. Unfortunately, ICANN's failure to enforce its minimal WHOIS and DNS abuse requirements has resulted in delayed mitigation efforts at a time when swift responses are needed to protect the public from COVID-19 scams. more
The Internet's users rely on domain name registration information for vital purposes, including providing security, problem-solving, and legal and social accountability. The data is so important that users perform more than two billion WHOIS queries every day. ICANN has instituted new data policies over the last two years, and is also directing a migration to a new technical protocol, RDAP, that will replace WHOIS access in the near future. So at this critical juncture, how is it all going? more
According to the company, the rollout will continue over the next few weeks to confirm that no major issues are discovered as this new protocol is enabled. more
Most of us, when we go to a website and see the little lock at the top of the browser, don't think twice and trust that we are communicating with the right company or organization. However, this is no longer the case because of a rather radical development that has largely occurred without notice or intervention by almost everyone. The web now has its own rapidly spreading version of CallerID spoofing that is about to get worse. more
The domain name system (DNS) grew to prominence during the initial, innocent days of the internet. During that time, early internet users tended to work for government or education organizations where trust was assumed, and security was not even a consideration. Since the online community was small and the internet was sparsely used, the importance of DNS was not widely understood, and as a consequence, left undefended. more
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
Public Interest Registry is the industry leader of DNS Anti-Abuse efforts on the Internet. Since our inception, we have worked to empower people and organizations that use the Internet to make the world a better place. Whether a .ORG is the foundation of an individual voice, a global non-profit, or any organization that is part of the mission-driven .ORG community, we are proud to have earned the trust of so many dedicated users. more
A group of leading domain name registries and registrars have joined forces in the fight against abuse in the Domain Name System (DNS), by developing a "Framework to Address Abuse." Each contributing company has shared its expertise and experience mitigating abusive practices with the goal of submitting the resulting Framework as a foundational document for further discussion in the multistakeholder community. more
The design of DNS included an important architectural decision: the transport protocol used is user datagram protocol (UDP). Unlike transmission control protocol (TCP), UDP is connectionless, stateless, and lightweight. In contrast, TCP needs to establish connections between end systems and guarantees packet ordering and delivery. DNS handles the packet delivery reliability aspect internally and avoids all of the overhead of TCP. There are two problems this introduces. more
An entity called the Handshake Network claims its newly developed open source project offers advantages over the traditional naming and signature systems. more
Apollo 11 was the spaceflight which landed the first two humans on the Moon. Commander Neil Armstrong and lunar module pilot Buzz Aldrin landed the Apollo Lunar Module, Eagle, on July 20, 1969. Armstrong became the first person to step onto the lunar surface six hours later, and Aldrin joined him 19 minutes later. The two astronauts spent about two and a quarter hours outside the spacecraft, and they collected 47.5 pounds of lunar material to bring back. more
From time to time the IETF seriously grapples with its role with respect to technology relating to users' privacy. Should the IETF publish standard specifications of technologies that facilitate third-party eavesdropping on communications or should it refrain from working on such technologies? Should the IETF take further steps and publish standard specifications of technologies that directly impede various forms of third party eavesdropping on communications? more
