Privacy Matters: Is It Time To Abolish The WHOIS Database?

Recently, I entered my domain name in a "WHOIS" database query to test the results of the database by using WHOIS on a number of domain name registrar websites. WHOIS is a database service that allows Internet users to look up a number of matters associated with domain names, including the full name of the owner of a domain name, the name of the domain name hosting service, the Internet Protocol or I.P. number(s) corresponding to the domain name, as well as personally identifying information on those who have registered domain names. I was astonished to find... more

New CSC Research Finds Significant Lack of Redundancy for Enterprise DNS

As outlined in CSC's recent 2020 Domain Security Report: Forbes Global 2000 Companies, cybercriminals are disrupting organizations by attacking the protocol responsible for their online presence -- their domain name system (DNS). When a DNS is overwhelmed with traffic due to a distributed denial of service (DDoS) attack or configuration error, content and applications become inaccessible to users, affecting both revenue and reputation. more

How to Track Online Malevolent Identities in the Act

Want to be a cybersleuth and track down hackers? It may sound ambitious considering that malevolent entities are extremely clever, and tracing them requires certain skills that may not be easy to build for the typical computer user. But then again, the best defense is offense. And learning the basics of sniffing out cybercriminals may not only be necessary nowadays, it has become essential for survival on the Web. So where can you begin? more

.hk the “Most Unsafe” Domains?

Hong Kong domains are the most dangerous in the world; this little factoid from a recent McAfee report generated quite a bit of media coverage, and even made TIME magazine's top stories list. But all is not as it seems, and aspects of the report may have been out of date before the report was even published. McAfee's study seems to be based on a year's worth of data, and last year was a particularly bad year for the Hong Kong domain, thanks to a gang of botnet spammers registering thousands of domains under the .hk ccTLD. These domains were most likely registered using stolen credit cards... more

The Internet is Dead - Long Live the Internet

Back in the early 2000s, several notable Internet researchers were predicting the death of the Internet. Based on the narrative, the Internet infrastructure had not been designed for the scale that was being projected at the time, supposedly leading to fatal security and scalability issues. Yet somehow the Internet industry has always found a way to dodge the bullet at the very last minute. more

Root Scaling Study Report is Out

Earlier this year, ICANN began to seriously consider the various effects of adding DNS protocol features and new entries into the Root Zone. With the NTIA announcement that the Root Zone would be signed this year, a root scaling study team was formed to assess the scalability of the processes used to create and publish the Root Zone. Properly considered, this study should have lasted longer than the 120 days -- but the results suggest that scaling up the root zone is not without risk -- and these risks should be considered before "green-lighting" any significant changes to the root zone or its processes. I, for one, would be interested in any comments, observations, etc. (The caveats: This was, by most measures, a rush job. My spin: This is or should be a risk assessment tool.) Full report available here [PDF]. more

98% Of Internet’s Main Root Server Queries Are Unnecccary: Should You Be Concerned?

A recent study by researchers at the Cooperative Association for Internet Data Analysis (CAIDA) at the San Diego Super Computer Center (SDSC) revealed that a staggering 98% of the global Internet queries to one of the main root servers, at the heart of the Internet, were unnecessary. This analysis was conducted on data collected October 4, 2002 from the 'F' root server located in Palo Alto, California.

The findings of the study were originally presented to the North American Network Operators' Group (NANOG) on October 2002 and later discussed with Richard A. Clarke, chairman of the President's Critical Infrastructure Protection Board and Special Advisor to the U.S. President for Cyber Space Security. more

78% of Cybersecurity Professionals Expect an Increase in DNS Threats, Yet Have Reservations

A recent survey conducted by the Neustar International Security Council confirmed the heightened interests on domain name system (DNS) security. The survey reveals that over three-quarters of cybersecurity professionals anticipate increases in DNS attacks, especially with more people shopping online amid the pandemic. Yet, close to 30% have reservations about their ability to respond to these attacks. more

Report Estimates Cybercrime Taking $600 Billion Toll on Global Economy

Cybercrime is costing businesses close to $600 billion, or 0.8 percent of global GDP, according to a report released today by McAfee, in partnership with the Center for Strategic and International Studies (CSIS). more

Internet Wars

A couple of days ago the BBC reported that a document called the Information Operations Roadmap (PDF) had been declassified and that it contained some pretty interesting stuff. The American dominance over the Internet, recently manifested by its unwillingness to hand over some of the critical control to UN-organizations, may have another side to it. more

Pandora’s Box - New US Cyber Security Bills Create a Worm Hole in the Internet Galaxy

There are two Bills that are floating through the corridors of power on the Hill that could potentially change the course of civil and political rights within the United States and the world. One was introduced through the House of Representatives and the other through the Senate. The two Bills touch on a common thread that are premised on "national security" however there are interesting challenges that will surface should the Bills be passed that affect global public interest that require further examination, introspection and discussion. more

IPv6, 5G and Mesh Networks Heightening Law Enforcement Challenges, Says Australian Government

In a submission to the Joint Committee on Law Enforcement's inquiry into Impact of new and emerging information and communications technology, the Department of Home Affairs and Australian Criminal Intelligence Commission (ACIC) warn law enforcement will be degraded by a number of new technologies. more

The Future of Email

While people may debate the death of email, there is no question that many email servers are already overloaded with spam. Current spam solutions are beginning to address the problem, but so far they all suffer from the arms race issue - as fast as we come up with new ways to fight spam, spammers are finding new ways to deliver it to us. While the functionality of email will certainly continue, the current system must change. When the change comes, it will deliver the future of email to Microsoft. more

Who is Blocking WHOIS?

On April 16 ICANN issued a breach notice to Turkish Registrar Alantron for not consistently providing access to its WHOIS database via Port 43, a command-line query location that all Registrars are required to supply under conditions of their contract with ICANN under section 3.3.1. Four days later they issued a breach to Internet Group do Brazil for the same problem. ... The WHOIS record, as we all know, is a massive fraud with illicit parties filling records with bogus information and hiding behind anonymity. more

Endpoint Rollbacks & Data Shadow Copies

Recently I was asked by a customer how they can easily set up rollback capabilities on the endpoints in their corporate network. They had seen the marketing hype by various security technology providers that their products included rollback capabilities they could utilize if/when one of their workstations or servers was infected by malware. Having gotten this question more than once, I thought it would be a good subject to share with a broader audience. more
