Preventing DNS Strain When You Deploy DNSSEC

The barriers to DNSSEC adoption are quickly disappearing. There are nearly 20 top-level domains that have already deployed DNSSEC including generic TLDs like .org and .gov. This July, the DNS root will also be signed, and will begin validating. At this point, the decision for remaining TLDs to deploy DNSSEC is really no longer a question. more

Verisign Outreach Program Remediates Billions of Name Collision Queries

A name collision occurs when a user attempts to resolve a domain in one namespace, but it unexpectedly resolves in a different namespace. Name collision issues in the public global Domain Name System (DNS) cause billions of unnecessary and potentially unsafe DNS queries every day. A targeted outreach program that Verisign started in March 2020 has remediated one billion queries per day to the A and J root name servers, via 46 collision strings. more

Notes from the DNS Privacy Workshop at NDSS 2021

For many years the consuming topic in DNS circles was that of the names themselves. If you wind the clock back twenty years or so, you will find much discussion about the nature of the Internet's namespace. Why were there both generic top-level labels and two-letter country codes? If we were going to persist with these extra-territorial generic country codes in the namespace, then how many should there be? Who could or should manage them? And so on. more

Security Psychology

I just came across a post telling of the Security and Human Behavior workshop. As some of you may be aware, I've been researching this subject for about two years now, and I am very excited that a conference has now happened! It means I did not waste the last two years of my life after all! more

Protecting Customer Data

There have been a number of reports recently about customer lists leaking out through Email Service Providers (ESPs). In one case, the ESP attributed the leak to an outside hack. In other cases, the ESPs and companies involved have kept the information very quiet and not told anyone that data was leaked. People do notice, though, when they use single use addresses or tagged addresses and know to whom each address was submitted. Data security is not something that can be glossed over and ignored. more

Heartbleed: Don’t Panic

There's been a lot of ink and pixels spilled of late over the Heartbleed bug. Yes, it's serious. Yes, it potentially affects almost everyone. Yes, there are some precautions you should take. But there's good news, too: for many people, it's a non-event. Heartbleed allows an attacker to recover a random memory area from a web or email server running certain versions of OpenSSL. The question is what's in that memory. It may be nothing, or it may contain user passwords (this has reportedly been seen on Yahoo's mail service), cryptographic keys, etc. more

German Authorities Seize Servers of Cybercriminal DDoS-for-Hire Service FlyHosting

FlyHosting had been open for business since November 2022 and was used for malicious activities such as hosting malware, botnet controllers, and carrying out DDoS attacks. more

The FBI and Scotland Yard vs. Anonymous: Security Lessons

A lot of people are fascinated by the news story that Anonymous managed to listen to a conference call between the FBI and Scotland Yard. Some of the interest is due to marvel that two such sophisticated organizations could be had, some is due to schadenfreude, and some is probably despair: if the bad guys can get at these folks, is anyone safe? more

New gTLD Queries at the Root & Heisenberg’s Uncertainty Principle

Since Verisign published its second SSR report a few weeks back, recently updated with revision 1.1, we've been taking a deeper look at queries to the root servers that elicit "Name Error," or NXDomain responses and figured we'd share some preliminary results. Not surprisingly, promptly after publication of the Interisle Consulting Group's Name Collision in the DNS [PDF] report, a small number of the many who are impacted are aiming to discredit the report. more

Is Your Router Spying on You?

If you've followed the telecom industry at all, you've heard of the effort to rip-and-replace Chinese network gear used mostly in cellular networks and in some fiber networks. The U.S. government ordered that such equipment be replaced, although it has funded the replacement in dribs and drabs. There has been heightened scrutiny of Chinese electronics since the recently discovered Beijing-sponsored cyberattacks that have been reported to have infiltrated the networks of major U.S. more

Why DNS Is Broken, Part 2: DoS Target

Before we get into what DNSSEC is and the benefits of it, let's talk about some of the other potential pitfalls of DNS. One of the most significant issues we have to deal with are denial-of-service (DoS) attacks. While DoS attacks are not specific to DNS we have seen DNS be a frequent target of these attacks. more

Is The Term “Cyberwarfare” Overstating the Case?

At the Virus Bulletin conference last month, Andrew Lee from ESET gave a talk entitled "Cyberwar: Reality or Weapon of Mass Distraction?" In it, Lee talks about how the term "cyberwar" is thrown around a lot these days. However, he disagreed with the use of the term because it uses inflationary language and overstates the case; today's "cyberwar" is not the same as a conventional ware. more

Microsoft Becomes the Latest Company to Join the Internet Society’s MANRS Initiative

Microsoft has joined the Mutually Agreed Norms for Routing Security (MANRS) initiative, supported by the Internet Society (ISOC) with the primary objective is to reduce the most common threats to the Internet's routing system. Microsft is the latest of a number of industry giants around the world - including Oracle, GÉANT, and Comcast - to join MANRS. more

Introduction: New gTLD Security and Stability Considerations (Part 1 of 5 )

Verisign recently published a technical report on new generic top-level domain (gTLD) security and stability considerations. The initial objective of the report was to assess for Verisign's senior management our own operational preparedness for new gTLDs, as both a Registry Service Provider for approximately 200 strings, as well as a direct applicant for 14 new gTLDs... However, in cataloging internal and external risks related to the new gTLD program, we found several far-reaching and long-standing issues that need to be further explored and/or resolved with varying levels of urgency. more

Join Live On Sunday - 2nd Registration Operations Workshop (ROW) In Dallas

This Sunday, March 22, 2015, the second Registration Operations Workshop (ROW) will be taking place at the Fairmont Dallas hotel from 12:30 -- 4:30 pm CDT. Discussion will include extensions to EPP, new encryption initiatives and also suggestions for ways to further automate DNS interactions between registries, registrars and DNS operators, including a need to do this for DNSSEC. more
