CAUCE Director Neil Schwartzman Wins Prestigious MAAWG Award

CAUCE Executive Director Neil Schwartzman won the prestigious Mary Litynski award on June 08, 2011 for his contributions to Internet anti-abuse efforts, including the passage of Canada's Anti-Spam Law. more

Who Broke the WHOIS?

As Internet services go, WHOIS held a lot of promise but has repeatedly failed to live up to its potential; raising the question "is it time to retire WHOIS?" The concept behind WHOIS was simple. For each and every registered domain name, provide the facility for querying details about who owns it, who administers it, when was it created and when it will expire. Unfortunately the service lost its way practically from day one after failing to agree upon or adhere to any formal structure of the content it provides. more

DNS Amplification Attacks: Out of Sight, Out of Mind? (Part 1)

Geoff Huston's recent post about the rise of DNS amplification attacks offers excellent perspective on the issue. Major incidents like the Spamhaus attack Geoff mentions at the beginning of his post make headlines, but even small attacks create noticeable floods of traffic. These attacks are easy to launch and effective even with relatively modest resources and we see evidence they're occurring regularly. Although DNS servers are not usually the target of these attacks the increase in traffic and larger response sizes typically stress DNS infrastructure and require attention from operation teams. more

Information Protection for the Domain Name System: Encryption and Minimization

In previous posts in this series, I've discussed a number of applications of cryptography to the DNS, many of them related to the Domain Name System Security Extensions (DNSSEC). In this final blog post, I'll turn attention to another application that may appear at first to be the most natural, though as it turns out, may not always be the most necessary: DNS encryption. (I've also written about DNS encryption as well as minimization in a separate post on DNS information protection.) more

The Human Factor in DDoS Attacks

Ripped from the headlines: A recent DDoS attack lasted an entire 60 days. In other news, a single site was attacked 218 times in Q2 alone. To those of us in the business of protecting Web infrastructure, these stories are hardly surprising. What's notable, though, is where they were reported, in The Financial, whose focus is banking and financial services, not technology. The reporters used the term "DDoS" as if it were as common as "hedge fund," something everyday business people, not just techies, grasp. It's this human element that caught my interest and got me thinking a little. more

The Internet as Weapon

One of the most striking and enduring dichotomies in the conceptualization of electronic communication networks is summed up in the phrase "the Internet as weapon." With each passing day, it seems that the strident divergence plays in the press -- the latest being Tim's lament about his "web" vision being somehow perverted. The irony is that the three challenges he identified would have been better met if he had instead pursued a career at the Little Theatre of Geneva and let SGML proceed to be implemented on OSI internets rather than refactoring it as HTML to run on DARPA internets. more

Chinese Hackers and Cyber Realpolitik

For many people the comments made by Michael Hayden, Former Director of the Central Intelligence Agency, at this week's Black Hat Technical Security Conference in Abu Dhabi may have been unsettling as he commented upon the state of Chinese cyber espionage. I appreciate the candor of his observations and the distinction he made between state-level motivations. In particular, his comment... more

Frequency of DDoS Attacks Risen by 40% While Duration of Attacks Decrease

The frequency of DDoS attacks has risen by 40% year on year while the duration of attacks decreased with 77% lasting ten minutes or less, according to a new report released by Corero Network Security. more

U.N. Approves Resolution to Combat Cybercrime Despite Opposition From E.U., the U.S. and Others

The U.N. General Assembly has approved a resolution to start the process of drafting a new international treaty against cybercrime despite objections from the European Union, the United States and other countries. The Russian-drafted resolution received approval from a 193-member world body with a vote of 79-60 and 33 abstentions. more

Anti-Phishing Working Group Proposes Use of Secure Hashing to Address GDPR-Whois Debacle

The AntiPhishing Working Group (APWG) in a letter to ICANN has expressed concern that the redaction of the WHOIS data as defined by GDPR for all domains is "over-prescriptive". more

Civil Society Hung Out To Dry in Global Cyber Espionage

This post was co-authored by Sarah McKune, a senior researcher at the Citizen Lab. Public attention to the secretive world of cyber espionage has risen to a new level in the wake of the APT1: Exposing One of China's Cyber Espionage Units report by security company Mandiant. By specifically naming China as the culprit and linking cyber espionage efforts to the People's Liberation Army, Mandiant has taken steps that few policymakers have been willing to take publicly, given the significant diplomatic implications. more

Unexpected Behaviour Observed With DNS Root Servers After Cryptographic Change

Responsibilities of the DNS: “Oh YES you will!”, “Oh NO you will not!”

What is the responsibility of the DNS? Should the DNS be responsible for policing traffic across its infrastructure? Should the blocking and blacklisting of names or throttling of query packets be the responsibility of the DNS? From experience I know my opening paragraph has started passionate debates in more than one section of this globe. We at CommunityDNS have found ourselves right in the middle of such heated debates. "Oh YES you will!", "Oh NO you will not!more

Secure Domain Foundation Launched to Help Internet Infrastructure Operators Fight Cybercrime

Experts and companies in the information security industry today announced the formation of the Secure Domain Foundation (SDF), a new, non-profit, community-driven organization devoted to the identification and prevention of Internet cyber crime utilizing the domain name system (DNS). more
