An Institute to Combat DNS Abuse

Over the last few years, it's become clear that abuse of the Domain Name System -- whether in the form of malware, botnets, phishing, pharming, or spam -- threatens to undermine trust in the Internet. At Public Interest Registry, we believe that every new .ORG makes the world a better place. That means anything that gets in the way of that is a threat, and that includes DNS Abuse. more

What Are the Connected Assets of Confirmed Fake FBI Domains?

Two months ago, the Federal Bureau of Investigation (FBI) alerted the public to a list of domains that could easily be mistaken to be part of its network. The list of artifacts contained a total of 92 domain names, 78 of which led to potentially malicious websites, while the remaining 14 have yet to be activated or are no longer active as of 23 November 2020. more

3 Most Scary Attacks that Leaked Personally Identifiable Information (PII) of Millions of Users

Cybercriminals are increasingly targeting Personally Identifiable Information (PII). The reason being "data is the new gold" in this digital world, and the more sensitive some data is, the more value it has. There is no more sensitive data than personally identifiable information because it contains enough information to identify you digitally. Examples of personally identifiable information include name, email, contact number, address, social security number, tax file number, banking or financial information, and more such data that helps identify you. more

WHOIS Record Redaction and GDPR: What's the Evolution Post-2018?

We all use the Internet daily. Practically every element of our reality has its equal in the virtual realm. Friends turn into social media contacts, retail establishments to e-commerce shops, and so on. We can't deny that the way the Internet was designed, to what it has become, differs much. One example that we'll tackle in this post is the seeming loss of connection between domains and their distinguishable owners. more

A Brief Look at the Domain Attack Surface of Streaming Media Companies

The term "attack surface" is often heard in cybersecurity conversations. It refers to the sum of all possible attack vectors or the vulnerabilities that threat actors can exploit to penetrate a target network or damage an organization somehow. An unused and forgotten subdomain, for instance, can become an attack vector when taken over. Certain categories of companies have very large attack surfaces. Such is the case of streaming media businesses like Netflix and HBO Max. more

Phishing 2020: A Concentrated Dose of Badness

How much phishing is there? Where is it occurring, and why? How can it be reduced? I and my colleagues at Interisle Consulting have just published a new study called Phishing Landscape 2020, designed to answer those questions. We assembled a deep set of data from four different, respected threat intelligence providers and enriched it with additional DNS data and investigation. The result is a look at phishing attacks that occurred in May through July 2020. more

Only Bad Actors Should Worry About the URS

With DNS abuse a topic of increased concern throughout the community, any controversy over adopting the Uniform Rapid Suspension System (URS) for all generic top-level domains (gTLDs) seems misplaced. The URS was designed as a narrow supplement to the Uniform Domain-Name Dispute Resolution Policy (UDRP), applicable only in certain tightly defined circumstances of clear-cut and incontrovertible trademark infringement involving the registration and use of a domain name. more

What Trademark Owners Need to Know to Avoid Reverse Domain Name Hijacking

A cybersecurity company recently attempted reverse domain name hijacking for an exact match domain name of its brand, and in so doing, failed in both its bid to take ownership of the domain and potentially damaged their reputation by using this somewhat nefarious tactic and abusing the Uniform Domain Name Dispute Resolution Policy (UDRP) process. more

DNS: An Essential Component of Cloud Computing

The evolution of the internet is anchored in the phenomenon of new technologies replacing their older counterparts. But technology evolution can be just as much about building upon what is already in place, as it is about tearing down past innovations. Indeed, the emergence of cloud computing has been powered by extending an unlikely underlying component: the more than 30-year-old global Domain Name System (DNS). more

The State of DNS Abuse: Moving Backward, Not Forward

ICANN's founding promise and mandate are optimistic -- ensure a stable and secure internet that benefits the internet community as a whole. Recent months, however, have highlighted the uncomfortable truth that ICANN's and the industry's approach to DNS abuse is actually moving backward, ignoring growing problems, abdicating on important policy issues, and making excuses for not acting. Further, the impending failure of ICANN's new WHOIS policy to address cybersecurity concerns will add fuel to the fire, resulting in accelerating DNS abuse that harms internet users across the globe. more

Beware of Abandoned Domain Names in this Turbulent Time and as the Global Economy Changes

The outbreak of COVID-19 has caused worldwide disruption -- for whole nations and their economies. Unfortunately, there will be some side effects for businesses. A number of brands will disappear from the streets and shelves, as businesses that fail to weather the storm will have to fold. Companies that do survive will likely focus more on their core markets, pulling brands out of higher risk, less profitable markets... more

Cybersecurity Is Failing Big-Time and This Is Hard to Fix

It has become clear that having a big cybersecurity war room is not enough to deliver true end-to-end security throughout the complex networks, systems and structures on which our modern society is based. Furthermore, looking at the forever changing draconian government interventions in this space, it is also obvious that they are often stabbing in the dark. more

Trust Binding

A few months ago, there was a lot of discussion that despite its claims, Zoom did not actually offer end-to-end encryption. They're in the process of fixing that, which is good, but that raises a deeper question: why trust their code? (To get ahead of myself, this blog post is not about Zoom.) If Zoom has the key but doesn't abuse it, there isn't a problem, right? Let's fast-forward to when they deploy true end-to-end encryption. Why do we trust their code not to leak the secret key? more

Zoom Cryptography and Authentication Problems

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 Security: The Good, the Bad, and the Business Model

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
