Defending Networks Against DNS Rebinding Attacks

DNS rebinding attacks are real and can be carried out in the real world. They can penetrate through browsers, Java, Flash, Adobe and can have serious implications for Web 2.0-type applications that pack more code and action onto the client. Such an attack can convert browsers into open network proxies and get around firewalls to access internal documents and services. It requires less than $100 to temporarily hijack 100,000 IP addresses for sending spam and defrauding pay-per-click advertisers. Everyone is at risk and relying on network firewalls is simply not enough. In a paper released by Stanford Security Lab, "Protecting Browsers from DNS Rebinding Attacks," authors Collin Jackson, Adam Barth, Andrew Bortz, Weidong Shao, and Dan Boneh provide ample detail about the nature of this attack as well as strong defenses that can be put in place in order to help protect modern browsers. more

NANOG 95: From Faster Fibre to Route Leaks, Operators Face Old Problems with New Tools

The NANOG 95 conference spotlighted breakthroughs in fibre optics, wireless technology, routing security, and quantum computing, offering a forward-looking assessment of internet infrastructure and its vulnerabilities, as reported by APNIC's Geoff Huston. more

AWS Unveils Route 53 “Accelerated Recovery” to Bolster DNS Resilience

AWS is introducing Route 53 Accelerated Recovery to help organizations maintain DNS control during regional outages, offering a 60-minute recovery objective and sustained access to key API operations for critical updates and traffic management. more

DNS Under Strain: Technical and Policy Challenges in Supporting the Internet of Autonomous Things

A new IETF draft outlines critical limitations of DNS in supporting the Internet of Autonomous Things, highlighting challenges related to latency, mobility, security, and privacy, and proposing architectural improvements to meet evolving machine-driven demands. more

Preparing DNSSEC for the Post-Quantum Era

To prepare DNS security for a post-quantum future, Verisign and partners are testing new cryptographic strategies that balance security, performance, and feasibility, especially through the novel Merkle Tree Ladder mode for managing large signatures. more

eco and AV-Test Publish Monthly topDNS Reports for Internet Service Providers

eco's topDNS initiative and AV-Test are publishing monthly reports to help ISPs detect and mitigate DNS abuse by analysing malware, phishing, and PUA trends, creating a long-term data foundation for industry-wide transparency. more

Overcoming DNSSEC Challenges: A Guide for TLDs

Despite offering robust protection for the Domain Name System, DNSSEC suffers from poor adoption due to its complexity, cost, and operational risks. Automation and algorithmic improvements now offer practical solutions for broader deployment. more

Centralizing DNS Data for Security, Compliance, and Performance

Private DNS data lakes consolidate fragmented logs into a centralised platform, improving visibility, security, and compliance. They enable advanced analytics, strengthen threat detection, and help organisations optimise network performance in increasingly complex IT environments. more

14th Registration Operations Workshop Set for September 30, 2025

The Registration Operations Workshop (ROW), an informal gathering of DNS professionals, is set to continue its tradition of fostering technical dialogue and knowledge-sharing across the domain name ecosystem. more

Polish Presidential Veto Threatens Starlink Continuity in Ukraine

Earlier this week, Poland’s new President, Karol Nawrocki, vetoed amendments to the Act on Assistance to Citizens of Ukraine, provoking debate over critical satellite connectivity. Deputy Prime Minister and Minister of Digital Affairs Krzysztof Gawkowski warned that the veto “de facto switched off Starlink for Ukraine,” potentially disrupting connectivity for hospitals, schools, and government operations. more

The Edgemoor Research Institute and TWNIC Launch Project Jake to Advance DNS Security and Data Transparency

The Edgemoor Research Institute (ERI) and Taiwan's .TW Registry (TWNIC) have announced a three-year strategic partnership to enhance Domain Name System (DNS) data management and internet security. The collaboration focuses on joint research, data sharing, and capacity building, aiming to strengthen global internet infrastructure and governance. more

The Latest DNS Threat Landscape: Why CISOs Must Rethink Blocking Strategies

Cybercriminals live by the tenet "If it ain't broke, don't fix it." They'll use the same tactics repeatedly until they no longer work, then switch things up. That's why CISOs and their security teams maintain constant vigilance. Underscoring this, recent analysis of global DNS activity found that new domains continue to be a major tactic for bad actors. more

IS3C Report: Socio-Political and Technical Impacts of Post Quantum Cryptography Policies

At the 20th Internet Governance Forum in Lillestrøm, Norway, the UN Internet Governance Forum's dynamic coalition Internet Standards, Security and Safety (IS3C) released its new report on post-quantum policies. This report presents the findings of a collaborative study undertaken by IS3C and the French domain name registry Afnic and examines the critical need for Post-Quantum Cryptography (PQC) to achieve greater security in the ever-expanding global IoT landscape. more

A Targeted Blueprint for Tackling DNS Abuse

The NetBeacon Institute is pleased to publish its White Paper: Proposal for PDPs on DNS Abuse. We created this paper to support and advance ICANN Community discussions on potential policy development related to DNS Abuse. From our unique perspective, we believe there are a number of issues that are constrained enough to be a successful ICANN PDP and can make a meaningful difference in our collective work against DNS Abuse. more

How New Domains are Driving DNS-based Attacks

Cyber criminals are the kings of recycling. Once they've found a tactic that works well, they'll keep doing it as long as they can get away with it. That's why it's so important for research teams to keep a close eye on what's happening behind the scenes with web traffic. Case in point? Our team at DNSFilter recently analyzed global DNS activity from the first quarter of 2025 and identified several notable trends. more
