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

Half of Phishing Sites in the Wild Have SSL Certificates and Show Padlock Security Icon, Study Finds

A new study by anti-phishing company PhishLabs reveals 49 percent of all phishing sites in the third quarter of 2018 had Secure Sockets Layer or SSL with HTTPS in their URL. 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

US Senators Urge Canada to Drop China’s Huawei Technologies in Building Future Telecom Networks

U.S. Senators Mark Warner, a Virginia Democrat, and Marco Rubio, a Florida Republican, both critics of China, have urged Canada to consider dropping China's Huawei Technologies from helping to build next-generation 5G telecommunications networks. more

Where Every Phisher Knows Your Name

Spear phishing is the unholy love child of email spam and social engineering. It refers to when a message is specifically crafted, using either public or previously stolen information, to fool the recipient into believing that it's legitimate. This personalization is usually fairly general, like mentioning the recipient's employer (easily gleaned from their domain name.) Sometimes they address you by name. Much scarier is when they use more deeply personal information stolen from one of your contacts... more

Russian Cyberattack Disrupts Operations at Japan’s Largest Maritime Port: Global Threat Intensifies

Japan's largest maritime port, the Port of Nagoya, suffered significant disruption due to a cyberattack, allegedly by the Russian group Lockbit 3.0. The attack, involving ransomware that locks systems until a payment is made, resulted in a terminal outage on Tuesday, with operations expected to resume Thursday. more

Google Reports 18 Million Daily COVID-19 Related Malware, Phishing Emails Per Day

During the last week, Google says it has been seeing 18 million malware and phishing emails related to COVID-19 daily. This, the company reported today, "is in addition to more than 240 million COVID-related daily spam messages." more

Software Insecurity: The Problem with the White House Cybersecurity Proposals

The White House has announced a new proposal to fix cybersecurity. Unfortunately, the positive effects will be minor at best; the real issue is not addressed. This is a serious missed opportunity by the Obama adminstration; it will expend a lot of political capital, to no real effect... The proposals focus on two things: improvements to the Computer Fraud and Abuse Act and provisions intended to encourage information sharing. At most, these will help at the margins; they'll do little to fix the underlying problems. more

Foreign Hackers Attack Canadian Government

An unprecedented cyberattack on the Canadian government also targeted Defence Research and Development Canada, making it the third key department compromised by hackers, CBC News has learned. ... While there is no definitive proof, of course, that China was behind these attacks, there is a lot of circumstantial evidence that points in that direction. China (allegedly) has a long history of engaging in espionage activities in order to gain access to information. In the United States, this is sometimes referred to as cyber warfare, but I think that cyber espionage is a better choice of terms. 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

The FCC Cyber Trust Label Gambit: Part II

Sixty years ago, Paul Baran and Sharla Boehm at The RAND Corporation released a seminal paper that would fundamentally reshape the cyber world forever more. Their paper, simply known as Memorandum RM -- 1303, described how specialized computers could be used to route digital communications among a distributed universe of other computers. It set the stage for a flood of endless developments that resulted in the interconnected world of everything, everywhere, all the time. 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

The Spamhaus Distributed Denial of Service - How Big a Deal Was It?

If you haven't been reading the news of late, venerable anti-spam service Spamhaus has been the target of a sustained, record-setting Distributed Denial-of-Service (DDoS) attack over the past couple of weeks... Of course, bad guys are always mad at Spamhaus, and so they had a pretty robust set-up to begin with, but whoever was behind this attack was able to muster some huge resources, heretofore never seen in intensity, and it had some impact, on the Spamhaus website, and to a limited degree, on the behind-the-scenes services that Spamhaus uses to distribute their data to their customers. 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

Where Domain Security Meets the Supply Chain Crunch

Over the last two years, we've all faced supply shortages on items we previously never thought could be in short supply. Most recently, the baby formula and semiconductor markets were hit. Before that, supply chain attacks on Colonial Pipeline and JBS Foods showed us that an attack on one company through a singular point of compromise has the potential to disrupt an entire network of connected companies, products, partners, vendors, and customers. more
