How the Verified Mark Certificate (VMC) Makes the Mailbox Safer

Nowadays, with increasing digitalization and internet usage, email is a central communication tool. This holds true even despite the high popularity of instant messaging apps and social media. Email remains the favorite means of business communication worldwide, both in B2B and B2C. In 2019, 293.6 billion emails were sent and received. By 2025, this number will grow even more. It is predicted that we will send and receive 376.4 billion emails per day. In this scenario, implementing security features for email communications has become absolutely essential. more

Phishing: An Interesting Twist on a Common Scam

After Two Security Assessments I Must Be Secure, Right? Imagine you are the CIO of a national financial institution and you've recently deployed a state of the art online transaction service for your customers. To make sure your company's network perimeter is secure, you executed two external security assessments and penetration tests. When the final report came in, your company was given a clean bill of health. At first, you felt relieved, and confident in your security measures. Shortly thereafter, your relief turned to concern. ...Given you're skepticism, you decide to get one more opinion. ...And the results were less than pleasing. more

Survey Results Expose Widespread DNS Vulnerabilities

The Measurement Factory and Infoblox have announced results of a survey of more than 1.3 million Internet-connected, authoritative domain name system (DNS) servers around the globe. The results of the survey indicate that as many as 84 percent of Internet name servers could be vulnerable to pharming attacks, and that many exhibit other security and deployment-related vulnerabilities. The surveys consisted of several queries directed at each of a large set of external DNS servers to estimate the number of systems deployed today and determine specific configuration details. more

Mitigating DDoS

Your first line of defense to any DDoS, at least on the network side, should be to disperse the traffic across as many resources as you can. Basic math implies that if you have fifteen entry points, and each entry point is capable of supporting 10g of traffic, then you should be able to simply absorb a 100g DDoS attack while still leaving 50g of overhead for real traffic... Dispersing a DDoS in this way may impact performance -- but taking bandwidth and resources down is almost always the wrong way to react to a DDoS attack. But what if you cannot, for some reason, disperse the attack? more

Online Drug Traffic and Registrar Policy

Last month I published an article called "What's Driving Spam and Domain Fraud? Illicit Drug Traffic" which explained how the many of the troublesome online crime issues are related to the online sale of narcotics and dodgy pharmaceuticals. Since this article was published we have witnessed one of the largest international law enforcement efforts against online drug traffic (Operation Pangea II)... more

DNS Clients Do Request DNSSEC Today

After the DNS root zone was finally signed and a number of Top-Level Domains (TLDs) began signing their zones, we were curious to see how many clients actually request DNSSEC information. We looked at the RIPE NCC server that provides secondary service to several country code top-level domains (ccTLDs). more

Proxy-Privacy User Higher for Illicit Domains

WHOIS issues are looming large for the ICANN meeting next week, starting with an all-day WHOIS Policy Review on Sunday (background). WHOIS is a subject that has been the recent topic of a number of issues including a debacle over potentially disclosing the identities of compliance reporters to spammers and criminal domainers. more

New Chapter Working Groups Open Closed Doors

One thing was clear from a recent presentation by the new leaders of the SF-Bay Internet Society (ISOC) Chapter Working Groups: inclusion and collaboration will be the key to these groups' success. As Dr. Brandie Nonnecke, the Internet Governance Working Group (WG) Chair said, "We haven't yet cracked the code on what 'multistakeholder' means." But that won't stop her and Dr. Jaclyn Kerr, the Data Protection, Privacy, and Security WG Chair, from trying. more

The DNSSEC Industry Coalition Meets to “Make It So”

The DNSSEC Industry Coalition conducted its first face to face meeting on Friday, March 13, 2009 at Google's Washington, DC office. Google's fun filled meeting room was packed with organizations that share a keen interest in DNS Security through the implementation of DNSSEC. more

United Nations vs. ICANN: One ccTLD At A Time

What happens if ICANN fails? Who will run the DNS then?

Of course to many, ICANN already has failed -- spectacularly so. Critics have long complained that ICANN not only lacks accountability and legitimacy, but also that it is inefficient (at best) and downright destructive (at worst). According to these critics, ICANN's many sins include threatening the stability of the Internet, limiting access by imposing an artificial domain name scarcity, and generally behaving like a petulant dictator. more

Terrorism, New gTLDs, DAG4, and ICANN’s Continued US and Western Centric Bias

Those who have been involved in the ICANN process as long as I have naturally become accustomed to ICANN controversies at all levels. But the latest is a "wrong" of international ramifications. The four (4) versions of the Guidebook for the new generic Top-Level Domains (gTLDs) have been hundreds of pages long with a lot of The Good, The Bad, and to some, The Ugly. However, something new has appeared in the 4th and latest version called DAG4 can be called: "The Disturbing". more

What Next for Email Service Providers?

It's been a very bad month for ESPs, companies that handle bulk mailings for their clients. Several of them have had internal security breaches, leaking client information, client mailing lists, or both. Many have also seen clients compromised, with the compromised credentials used to send spam. The sequence of events suggests all the ESPs whose clients were compromised were themselves compromised first. (That's how the crooks knew who to attack.) more

OARC-40: Notes on the Recent DNS Operations, Analysis, and Research Centre Workshop

OARC held a 2-day meeting in February, with presentations on various DNS topics. Here are some observations I picked up from the presentations in that meeting... In a world where every DNS name is DNSSEC-signed, and every DNS client validates all received DNS responses, we wouldn't necessarily have the problem of DNS spoofing. Even if we concede that universal use of DNSSEC is a long time off ... more

RIPE NCC Publishes Case Study of youtube.com Hijack

As you may be aware from recent news reports, traffic to the youtube.com website was 'hijacked' on a global scale on Sunday, 24 February 2008. The incident was a result of the unauthorised announcement of the prefix 208.65.153.0/24 and caused the popular video sharing website to become unreachable from most, if not all, of the Internet. The RIPE NCC conducted an analysis into how this incident was seen and tracked by the RIPE NCC's Routing Information Service (RIS) and has published a case study... more
