2.6 Billion Records Were Stolen, Lost or Exposed Worldwide in 2017, an 88% Increase From 2016

Over the past five years, nearly 10 billion records have been lost, stolen or exposed, with an average of five million records compromised every day. more

Which Domains Stand the Strongest Against Phishing Attacks?

The latest Anti-Phishing Working Group (APWG) Global Phishing Survey, which analyzed over 100,000 phishing attacks in the first half of 2014, examines the progress that top level domains (TLDs) are making in responding to phishing attacks that use their TLDs. The report finds the .INFO domain has the lowest average phishing uptimes as compared to other TLDs, such as .COM and .NET. more

IPv6 Security Myth #5: Privacy Addresses Fix Everything!

Internet Protocol addresses fill two unique roles. They are both identifiers and locators. They both tell us which interface is which (identity) and tell us how to find that interface (location), through routing. In the last myth, about network scanning, we focused mainly on threats to IPv6 addresses as locators. That is, how to locate IPv6 nodes for exploitation. Today's myth also deals with IPv6 addresses as identifiers. more

Emerging Cyber-Security Threats and Implications for the Private Sector

The new gTLD program will have a profound impact on the private sector's increasing dominance over Internet information resources and ownership of critical registry technical infrastructure assets. It is already anticipated that only the private sector will take full advantage of the commercial possibilities... However, the successful introduction of new gTLDs will also create new challenges of security for the private sector. more

IPv6 Adoption Brings New Security Risks

Although IPv6 DDoS attacks are not yet a common occurrence, there are indications that malicious actors have started testing and researching IPv6 based DDoS attack methods. more

The Design of the Domain Name System, Part I

Over the past 30 years the Domain Name System has become an integral part of the operation of the Internet. Due to its ubiquity and good performance, many new applications over the years have used the DNS to publish information. But as the DNS and its applications have grown farther from its original use in publishing information about Internet hosts, questions have arisen about what applications are appropriate for publication in the DNS, and how one should design an application to work well with the DNS. more

2004: The Year That Promised Email Authentication

As the year comes to a close, it is important to reflect on what has been one of the major actions in the anti-spam arena this year: the quest for email authentication. With email often called the "killer app" of the Internet, it is important to reflect on any major changes proposed, or implemented that can affect that basic tool that many of us have become to rely on in our daily lives. And, while many of the debates involved myriads of specialized mailing lists, standards organizations, conferences and even some government agencies, it is important for the free and open source software (FOSS) community as well as the Internet community at large, to analyze and learn lessons from the events surrounding email authentication in 2004. more

Patching is Hard

There are many news reports of a ransomware worm. Much of the National Health Service in the UK has been hit; so has FedEx. The patch for the flaw exploited by this malware has been out for a while, but many companies haven't installed it. Naturally, this has prompted a lot of victim-blaming: they should have patched their systems. Yes, they should have, but many didn't. Why not? Because patching is very hard and very risk, and the more complex your systems are, the harder and riskier it is. more

Study Finds Spammers Use P2P Harvesting to Spam Millions

A recent study conducted by Blue Security reports how Internet users can unknowingly expose their contacts' emails addresses to Spammers while sharing files, music, games and DVDs over Peer-to-Peer (P2P) networks. The study has uncovered hundreds of incidents where files containing email addresses were made accessible in P2P networks. more

Understanding the Threat Landscape: Indicators of Compromise (IOCs)

I previously provided a brief overview of how Verisign iDefense characterizes threat actors and their motivations through adversarial analysis. Not only do security professionals need to be aware of the kinds of actors they are up against, but they should also be aware of the tactical data fundamentals associated with cyber-attacks most commonly referred to as indicators of compromise (IOCs). Understanding the different types of tactical IOCs can allow for quick detection of a breach... more

IPv6 Over Satellite: Pie in the Sky?

I am writing this from the Satellite 2008 conference in Washington, D.C. As I make my way through the exhibits, I see many vendors advertising IP capabilities in their hardware products or network services. But when asked about IPv6 support, the common reply is a not so believable "it is on our roadmap" followed by a somewhat vague delivery date. Although IPv6 development has been slow across the board, it appears to be moving even more slowly in the satellite world... more

Consumer Trust? Not at ICANN Compliance

Every person and every entity must have a philosophy if they are to be successful. Consumer trust is one of the key issues at the heart of keeping the Internet open as well as prosperous. The ICANN Affirmation of Commitments was signed in 2009 and has been the guiding principle for ICANN's activities going forward. The title of section 9.3 is Promoting competition, consumer trust, and consumer choice. This section is in essence the embodiment of the commitment of ICANN. more

1 Terabit DDoS Attacks Become a Reality; Reflecting on Five Years of Reflections

Reflection amplification is a technique that allows cyber attackers to both magnify the amount of malicious traffic they can generate, and obfuscate the sources of that attack traffic. For the past five years, this combination has been irresistible to attackers, and for good reason. This simple capability, of turning small requests into larger, 'amplified' responses, changed the Distributed Denial of Service (DDoS) attack landscape dramatically. more

Verisign’s Perspective on Recent Root Server Attacks

On Nov. 30 and Dec. 1, 2015, some of the Internet's Domain Name System (DNS) root name servers received large amounts of anomalous traffic. Last week the root server operators published a report on the incident. In the interest of further transparency, I'd like to take this opportunity to share Verisign's perspective, including how we identify, handle and react, as necessary, to events such as this. more

IPv6 Security Myth #10: Deploying IPv6 is Too Risky

After a quick break to catch our breath (and read all those IPv6 Security Resources), it's now time to look at our tenth and final IPv6 Security Myth. In many ways this myth is the most important myth to bust. Let's take a look at why... Myth: Deploying IPv6 Makes My Network Less Secure... I can hear you asking "But what about all those security challenges we identified in the other myths?" more
