Enabling Privacy Is Not Harmful

The argument for end-to-end encryption is apparently heating up with the work moving forward on TLSv1.3 currently in progress in the IETF. The naysayers, however, are also out in force, arguing that end-to-end encryption is a net negative... The idea of end-to-end encryption is recast as a form of extremism, a radical idea that should not be supported by the network engineering community. Is end-to-end encryption really extremist? Is it really a threat to the social order? more

Surveillance Capitalist in Chief

Surveillance capitalism monetizes private data that it collects without consent of the individuals concerned, data to analyze and sell to advertisers and opinion-makers. There was always an intricate relationship between governments and surveillance capitalists. Governments have the duty to protect their citizens from the excesses of surveillance capitalism. On the other hand, governments use that data, and surveillance capitalism's services and techniques. more

NXDOMAINS, SSAC’s SAC045, and New gTLDs (Part 4 of 5)

In 2010, ICANN's Security and Stability Advisory Committee (SSAC) published SAC045 [PDF], a report calling attention to particular problems that may arise should a new gTLD applicant use a string that has been seen with measureable (and meaningful) frequency in queries for resolution by the root system. The queries to which they referred involved invalid Top-Level Domain (TLD) queries (i.e., non-delegated strings) at the root level of DNS, queries which elicit responses commonly referred to as Name Error, or NXDomain, responses from root name servers. more

A Trebuchet Defence in the Age of the Augmented Reality Cyberwarrior

I've been ruminating on this for a while, this follow-up that was a decade in the offing. My article Trench Warfare in the Age of The Laser-Guided Missile from January 2007 did pretty good in terms of views since I wrote it. Less so in terms of how well the ideas aged or didn't, but that's the nature of the beast. Everything gets worse, and simultaneously, better, and so here we are: Using embarrassingly ancient approaches to next-generation threats. Plus ça change. more

And the Wait Continues for .Corp, .Home and .Mail Applicants

On 6 March 2017, ICANN's GDD finally responded to an applicant letter written on 14 August 2016 to the ICANN Board. This was not a response from the ICANN Board to the letter from 2016 but a response from ICANN staff. The content of this letter can best be described as a Null Response. It reminded the applicants that the Board had put the names on hold and was still thinking about what to do. more

Understanding the Threat Landscape: Basic Methodologies for Tracking Attack Campaigns

The indicators of compromise (IOCs) outlined in my last blog post can be used as a baseline for developing intrusion sets and tracking attack campaigns and threat actors. When launching an attack, threat actors use a variety of vectors and infrastructure, which Verisign iDefense analysts -- as well as analysts across the cybersecurity community -- correlate to group attacks, tracking actors and determining attack methods. more

Biggest Botnet Takedown to Date

Yesterday law enforcement officials arrested 6 people and charged them with running a massive internet fraud ring. Over 4 million PCs were part of the botnet. According to the FBI, "the cyber ring used a class of malware called DNSChanger to infect approximately 4 million computers in more than 100 countries. There were about 500,000 infections in the U.S., including computers belonging to individuals, businesses, and government agencies such as NASA." more

Typosquatting Claims Against Security Researcher Are Legally Complicated - Gioconda v. Kenzie

Kenzie is a security researcher who has registered numerous domain names that are typographic errors of well-known trademarks (e.g., rnastercard, rncdonalds, nevvscorp, rncafee, macvvorld, rnonster, pcvvorld). He points the domain names to the actual sites in question (e.g., rncdonalds points to mcdonalds.com), but he is looking to demonstrate how these typo domains are used for "social engineering" attacks. 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

Cybersecurity Considerations in the Work-From-Home Era

Verisign is deeply committed to protecting our critical internet infrastructure from potential cybersecurity threats, and to keeping up to date on the changing cyber landscape. Over the years, cybercriminals have grown more sophisticated, adapting to changing business practices and diversifying their approaches in non-traditional ways. We have seen security threats continue to evolve in 2020, as many businesses have shifted to a work from home posture due to the COVID-19 pandemic. more

Response Policy Zones (RPZs): Use as a Blocklisting Process

Gradually it seems the word is spreading about a new blocking methodology to interrupt the ability of end users to click and visit phishing sites - thereby having their personal information/credentials at risk. This is the DNS Response Policy Zones. DNS RPZs allows companies that run recursive resolvers to create a zone that will not resolve specific domains. more

The CEO Is Not Who They Seem: Deepfakes Target Corporate Trust

A surge in AI-generated deepfake scams is reshaping the cybersecurity threat landscape, with fraudsters now impersonating company executives to deceive employees and siphon off millions. more

Authenticated Resolution and Adaptive Resolution: Security and Navigational Enhancements to the DNS

The Domain Name System (DNS) has become the fundamental building block for navigating from names to resources on the internet. DNS has been employed continuously ever since its introduction in 1983, by essentially every internet-connected application and device that wants to interact online. Emerging from an era where interconnection rather than information security was the primary motivation, DNS has gradually improved its security features. more

Internet Society Releases Internet of Things (IoT) Overview: Understanding the Issues and Challenges

Near the end of the first decade of this century, the world reached an Internet milestone. The number of Internet-connected devices surpassed the number of people alive on planet Earth. At the time, seven billion devices had already been connected to the Internet, and this went completely unnoticed by most people. This moment represented an important sign of the rapid pace in which we are adopting technology and embracing Internet connectivity. more

Placing New Domain Names in Temporary “Penalty Box” Could Deter Malicious Use, Says Paul Vixie

Paul Vixie proposes a 'cooling-off period' when domain names are registered in order to help detect and deter malicious activity. "There's no legitimate reason for a new domain name to be registered and go live in less than a minute... more
