A DNS View of Lockdown

At NANOG 79 earlier this month Craig Labowitz from Nokia Deepfield presented on the impact on the COVID-19 pandemic on Internet use. The approach to the analysis used real-time streaming telemetry from Communication Service Provider (CSP) backbone and aggregation routers, and the data analysis covered content provider networks in North America, Europe and parts of Asia. more

A Failed Whois Policy

ICANN's two-year effort to purportedly preserve the Whois public directory to the greatest extent possible while complying with GDPR has failed. Under the latest proposal, the Whois database, once a contractually-required directory of domain name registrants, will be gutted to the point of virtual worthlessness, as registrars, registries, academics, and hand-wringing others ignored the public interest and imposed ever-higher barriers to legitimate, GDPR-compliant access to registration data. more

Cybersquatting and Geopolitics Heats Up

Cybersquatting is so 2000, or so we thought. The Uniform Dispute Resolution Policy (UDRP) at WIPO has been chugging along for several years now, methodically determining if complainants IP rights have been violated and reassigning "ownership" of domain names. Typically, the cases are fairly boring. But some recent developments in the world of 800 lb search gorillas, Google and Baidu, suggests that the regime could be faced with substantial pressure in the near future. more

VeriSign Director Charged with Securities Fraud

Bloomberg is reporting that Gregory Reyes is facing criminal and civil charges in relation to securities fraud. Reuters and the Mercury News also have coverage. "Former Brocade Communications Systems Inc. Chief Executive Officer Gregory Reyes became the first CEO charged in the U.S. probe of the backdating of stock option grants to create lucrative employee pay packages." more

Homeland Security Department Was Warned About DNSSEC Key Ownership and Trust Issues

The Internet Governance Project has unearthed a consultancy report to the U.S. Department of Homeland Security (DHS) that makes it clear that the issue of root signing and DNSSEC key management has been recognized as a political issue within the US government for long time. 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

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

NTIA Awards IANA Functions Contract to ICANN

The U.S. Commerce Department's National Telecommunications and Information Administration (NTIA) announced today that it has awarded the Internet Assigned Numbers Authority (IANA) functions contract to the Internet Corporation for Assigned Names and Numbers (ICANN). The IANA functions are key technical services critical to the continued operations of the Internet's underlying address book, the Domain Name System (DNS). more

DNSSEC is But One Link in the Security Chain

As the implementation of DNSSEC continues to gather momentum and with a number of ccTLDs, and the '.org' gTLD having deployed it into their production systems, I think it is worth pausing to take a look at the entire DNSSEC situation. Whilst it is absolutely clear that DNSSEC is a significant step forward in terms of securing the DNS, it is but one link in the security chain and is therefore not, in itself, a comprehensive solution to fully securing the DNS system. more

DNSSEC and DNS over TLS

The APNIC Blog has recently published a very interesting article by Willem Toorop of NLnet Labs on the relationship between Security Extensions for the DNS (DNSSEC) and DNS over Transport Layer Security. Willem is probably being deliberately provocative in claiming that "DoT could realistically become a viable replacement for DNSSEC." If provoking a reaction was indeed Willem's intention, then he has succeeded for me, as it has prompted this reaction. more

More on the Front Running Class Action Suit

Several people pointed out that although the suit still hasn't appeared in PACER, copies of the complaint are available online, including this one [PDF] at Lextext. Having read it, I'm rather underwhelmed... I do not purport to be a lawyer (nor do I usually play one on the net), but it's hard to see how the facts, which are not in serious dispute, would support any of these charges. more

97% of All Global 2000 Companies at Risk from SAD DNS Attack

There is a new threat in town known as "SAD DNS" that allows attackers to redirect traffic, putting companies at risk of phishing, data breach, reputation damage, and revenue loss. What is SAD DNS? No, it isn't the domain name system (DNS) feeling moody, but an acronym for a new-found threat -- "Side-channel AttackeD DNS" discovered by researchers that could revive DNS cache poisoning attacks. more

Internet Repotting About to Start!

February 4th 2008 will be the day the repotting of the internet finally starts. A milestone of sorts for some people who spent a good part of the last five years getting us this far. It should now be finally possible for a IPv6 only device to have a chance to communicate on the Internet. Indeed, today, IPv6 address information is not included in most root DNS servers. Some good write-ups are already appearing on the subject covering the relevance of this development... Why get excited as there are practically no IPv6 only devices yet, some will bemoan. Well, one can hear a distant rumbling of such devices coming, alongside the mobile internet... more

Just Say No, to Your ISP Subverting Your DNS Queries

Over the past few weeks I have been seeing reports that some ISP's are actually subverting DNS queries to their own DNS server. Oh the humanity! What this means is that when you (your computer) does a UDP or TCP Port 53 DNS query the ISP is intercepting that and directing it to their own servers. Has anyone been told by their ISP that they are doing this? No? I didn't think so... more

Domain Name Registries Must Do More to Protect Highly-Trafficked Domains

With the recent attacks against high-profile New Zealand domain names including Coca-Cola.co.nz and F-Secure.co.nz, fingers are naturally pointing to Domainz, the registrar of record for these domains, as the party responsible for this lapse in security. While domain name registrars certainly need to ensure the security and stability of their systems, domain name registries must also step up and take responsibility for mitigating risks posed by hackers... more
