Do I need DDoS protection? A Realistic Look at the Decision Process

There has been a recent spate of well publicised Distributed Denial of Service (DDoS) attacks that bring websites down and render them useless, including Evernote and most recently Feedly. In light of this, here are some comments and tips to help companies evaluate and prepare not to be held for ransom or suffer lost reputation and sales as a result. more

ICANN Facing Critical Choice for Plan to Change DNS Cryptographic Key

While the majority of ICANN's Security and Stability Advisory Committee (SSAC) have given the organization the green signal to roll, or change, the "top" pair of cryptographic keys used in the DNSSEC protocol, commonly known as the Root Zone KSK (Key Signing Key), five members of the committee advised against the October 11 rollover timeline. more

A Closer Look at Postponing of the Root Zone KSK Rollover Decision

On Sept. 27, Internet Corporation for Assigned Names and Numbers (ICANN) announced that the first root zone Key Signing Key (KSK) rollover - originally scheduled to take place on Oct. 11 - will be postponed. Although this was certainly a difficult decision, we fully agree that erring on the side of caution is the best approach to take. In this blog post, I want to explain some of the involvement Verisign has had in KSK rollover preparations, as well as some of the recently available research opportunities which generated data that we shared with ICANN related to this decision. more

Video: Highlights of the DNSSEC Key Signing Ceremony

ICANN video highlighting last week's historical DNSSEC key signing ceremony held in a high security data centre located in Culpeper, VA, outside of Washington, DC. "During the ceremony, participants were present within a secure facility and witnessed the preparations required to ensure that the so-called key-signing-key (KSK) was not only generated correctly, but that almost every aspect of the equipment, software and procedures associated with its generation were also verified to be correct and trustworthy." more

Updates on the Georgian Cyber Attacks

This is an update of my previous post on the subject. To be honest here, no one truly knows what's going on in Georgia's Internet except for what can be glimpsed from outside, and what has been written by the Georgians on their blog (outside their country). They are probably a bit busy avoiding kinetic bombing... more

Cryptominers Infected 10x More Organizations Than Ransomware in 2018

A new security report reveals cryptominers infected ten times more organizations than ransomware in 2018, but only one in five IT security professionals were aware their company's networks had been infected by mining malware. more

Was the ClimateGate Hacker Justified? Join the Debate!

A few days ago a story broke where someone hacked into a global warming research institute and stole all emails from the past 10 years, proving a conspiracy. In the vast amount of emails stolen, some emails were also found with clear-cut lies, showing how some scientists conspired to deceive in scientific research about data that did not fit their agenda of proving global warming. I am opening the subject for debate... more

The Story of Conficker and the Industry Response

On November 2, 2009, Microsoft released its seventh edition of the Security and Intelligence Report (SIR). The SIR provides an in-depth perspective on the changing threat landscape including software vulnerability disclosures and exploits, malicious software (malware), and potentially unwanted software. Using data derived from hundreds of millions of Windows computers, and some of the busiest online services on the Internet, this report also provides a detailed analysis of the threat landscape and the changing face of threats and countermeasures and includes updated data on privacy and breach notifications. The following is an excerpt from the SIR, pp 29-32, about the Conficker worm and the industry response that showed an incredible amount of collaboration across vendors. more

Introduction: ICANN’s Alternative Path to Delegation (Part 1 of 4)

As widely discussed recently, observed within the ICANN community several years ago, and anticipated in the broader technical community even earlier, the introduction of a new generic top-level domain (gTLD) at the global DNS root could result in name collisions with previously installed systems. Such systems sometimes send queries to the global DNS with domain name suffixes that, under reasonable assumptions at the time the systems were designed, may not have been expected to be delegated as gTLDs. 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 RPZ, Malicious Domains… Bring Your Own Policy. Dress Casual.

Paul observed that most new domain names are malicious. Are they? Since the "dawn of tasting", some 30 million domain names have been created for the purposes of interposition on existing name to resource mappings. That is a third of the .COM historical growth, and mostly in the last five years. ... It is difficult not to conclude that interposition on persistent, public referents is without malice, and that the malicious parties are advertisers seeking to transform public referents into private property, as promotional devices... more

Equifax Hacked, Nearly Half of US Population Affected

In an announcement today, credit reporting giant Equifax revealed a cybersecurity incident potentially impacting approximately 143 million U.S. consumers. more

Encryption and Securing Our Digital Economy

As G20 leaders from around the world gather this week, Germany wants them to agree to a concrete plan -- one that includes affordable Internet access across the world by 2025, common technical standards and a focus on digital learning. Today, the G20 economies, like so many other economies around the world, are digital and interconnected. Digital services have opened up new avenues for sustainable economic growth. more

VoIP/IP Telephony in Estonia: Disrupted by Botnets?

With my post earlier this month about the possibility of SIP botnets [also featured here on CircleID], I've had a number of people asking about more information and wondering about the possible impacts. And while I will write more on botnets in general, as far as the potential impact of "botnets" in general, one need only look over at the current situation in Estonia... Now, perhaps Russia is behind the attack... perhaps not. There are obviously much larger political issues going on between the two states. more

Notes from NANOG 69

NANOG 69 was held in Washington DC in early February. Here are my notes from the meeting. It would not be Washington without a keynote opening talk about the broader political landscape, and NANOG certainly ticked this box with a talk on international politics and cyberspace. I did learn a new term, "kinetic warfare," though I'm not sure if I will ever have an opportunity to use it again! more
