The State of RPKI as We Enter 2022

Resource Public Key Infrastructure (RPKI) is a method to secure internet routing traffic by cryptographically verifying routes. As we begin 2022, we look back at 2021 and see how the year saw another significant step towards its adoption. High-profile issues with the old trust-based model of Border Gateway Protocol, designed several decades ago, have shown the continued importance of protecting popular networks from mistakes or hackers. more

New Research from CSC on the Impact of COVID-19 on Internet Security and Safety

Hackers are using company domain names for malicious attacks more than ever before. Established research shows that phishing and related malware attacks most commonly occur from a compromised or hijacked legitimate domain name, a maliciously registered, confusingly similar domain name, or via email header spoofing. Domain security intelligence is the first line of defense in preventing domain cyberattacks. more

Observations on Resolver Behavior During DNS Outages

When an outage affects a component of the internet infrastructure, there can often be downstream ripple effects affecting other components or services, either directly or indirectly. We would like to share our observations of this impact in the case of two recent such outages, measured at various levels of the DNS hierarchy, and discuss the resultant increase in query volume due to the behavior of recursive resolvers. more

ICANN DNS Resolver Symposium – the Session Had Several Interesting Presentations That I Would Like to Comment On

ICANN hosted a Resolver Operator Forum in mid-December, and the session had several interesting presentations that I would like to comment on here... The first presentation in this forum was from Paul Mockapetris. He pointed to the original academic published paper, Development of the Domain Name System, by Paul Mockapetris and Kevin Dunlap, published in the proceedings of ACM SIGCOMM’88. The paper noted that by 1983 it was obvious that the shared HOSTS.TXT file was not a scalable solution... more

Ongoing Community Work to Mitigate Domain Name System Security Threats

For over a decade, the Internet Corporation for Assigned Names and Numbers (ICANN) and its multi-stakeholder community have engaged in an extended dialogue on the topic of DNS abuse, and the need to define, measure and mitigate DNS-related security threats. With increasing global reliance on the internet and DNS for communication, connectivity and commerce, the members of this community have important parts to play in identifying, reporting and mitigating illegal or harmful behavior, within their respective roles and capabilities. more

Registrar Influence on the Domain Security Posture of the Forbes Global 2000

In the 2021 Domain Security Report, we analyzed the trend of domain security adoption with respect to the type of domain registrar used, and found that 57% of Global 2000 organizations use consumer-grade registrars with limited protection against domain and DNS hijacking, distributed denial of service (DDoS), man-in-the-middle attacks (MitM), or DNS cache poisoning. On average, the adoption of domain security controls is two times higher for enterprise-class registrars than for those using consumer-grade registrars. more

A Three-Step Process to Chase Compulsive Domain Brand Squatters

Domain brand squatting can be defined as the unauthorized or dishonest use of a brand or company identifiers in domain names. It is often linked to the use of look-alike domains in bad faith, and we see it all the time. The threat actors behind these domains are called different names, though a prevalent one would be “typosquatters.” The Hot on the Trail of Compulsive Brand Squatters webinar showcased how these people are infiltrating the Internet. The first page of PhishTank’s valid phish search alone as of this writing tells us that domain brand squatting is a real and present danger. more

Why Domain Security Is Your First Line of Defense to Mitigate Phishing Attacks

According to the Cybersecurity and Infrastructure Security Agency (CISA), most cyberattacks, including ransomware and business email compromise, begin with phishing. Although losses due to ransomware now exceed billions annually, most ransomware protection and response measures don't protect against the most common phishing attacks. Established research shows that phishing attacks most commonly occur from a maliciously registered, confusingly similar domain name, a compromised or hijacked legitimate domain name, or via email header spoofing. more

Key Findings from the 2021 Domain Security Report

With cybercrime on the rise, companies in 2021 have experienced increased ransomware attacks, business email compromise (BEC), phishing attacks, supply chain attacks, and online brand and trademark abuse. While domain cyber risk is rising, the level of action being taken by Forbes Global 2000 companies to improve their domain security posture has remained unchanged, leaving these companies exposed to even more risk. The risk of not addressing your domain security can be catastrophic. more

Cryptographic Catastrophe Theory

Technologists and law enforcement have been arguing about cryptography policy for about 30 years now. People talk past each other, with each side concluding the other side are unreasonable jerks because of some fundamental incompatible assumptions between two conceptual worlds in collision. In the physical world, bank branches have marble columns and granite counters and mahogany woodwork to show the world that they are rich and stable. more

Euro 2020 Part Three: Domains (Revisited) and Other Channels

In this final article in the series of studies looking at Euro 2020-related infringements, we revisit domain name infringements and consider activity across other online channels, with a focus on social media and mobile apps. Following the original study, which looked at domains registered before May 2020 with names containing "euro2020" or "euro2021," we analyzed daily activity levels in the period immediately preceding and during the competition. more
