Canadian Spam Law Update

As you may know, there are two laws currently being discussed in Canadian legislative assemblies: Senate Bill S-220, a private member’s bill with private right of action and criminal remedies; Parliamentary Bill C-27, tabled by the government, with private right of action, coordination between various enforcement agencies... more

How to Steal Reputation

The term "reputation hijacking" continues to spread through the anti-spam community and the press. It's intended to describe when a spammer or other bad actor uses someone else's system -- usually one of the large webmail providers -- to send their spam. The idea is that in doing so, they're hijacking the reputation of the webmail provider's IPs instead of risking the reputation of IPs under their own control. But I really have to laugh (though mostly out of sadness) whenever this technique is described as something new... more

Cyber Security and the White House, Part 2 - Cyberwarfare

This is a follow-up to my previous post on Cybersecurity and the White House. It illustrates an actual cyberwarfare attack against Estonia in 2007 and how it can be a legitimate national security issue. Estonia is one of the most wired countries in eastern Europe. In spite of its status of being a former Soviet republic, it relies on the internet for a substantial portion of everyday life -- communications, financial transactions, news, shopping and restaurant reservations all use the Internet. Indeed, in 2000, the Estonian government declared Internet access a basic human right... more

Cyber Security and the White House

A few months ago, an article appeared on arstechnica.com asking the question "Should cybersecurity be managed from the White House?" During the recent presidential elections in the United States and the federal elections in Canada, the two major players in both parties had differing views that crossed borders. In the US, the McCain campaign tended to favor free market solutions to the problem of cybersecurity, and the Conservatives in Canada took a similar position... more

Another Attack, Another Reason for the Urgency of DNSSEC Adoption

News broke this week about an attack in Puerto Rico that caused the local websites of Google, Microsoft, Yahoo, Coca-Cola, PayPal, Nike, Dell and Nokia to be redirected for a few hours to a phony website. The website was all black except for a taunting message from the computer hacker responsible for the attack... more

Domain Name Registries Must Do More to Protect Highly-Trafficked Domains

With the recent attacks against high-profile New Zealand domain names including Coca-Cola.co.nz and F-Secure.co.nz, fingers are naturally pointing to Domainz, the registrar of record for these domains, as the party responsible for this lapse in security. While domain name registrars certainly need to ensure the security and stability of their systems, domain name registries must also step up and take responsibility for mitigating risks posed by hackers... more

Global DNS SSR Recap

This past February, around 100 DNS industry experts met in Atlanta, GA for the "The Global DNS Security, Stability, & Resiliency Symposium." Organized by ICANN and hosted by Georgia Tech, this event was to strengthen personal relationships between operators and review what we know about the DNS infrastructure... The content included three breakout groups over two days: Enterprise Use of DNS, DNS in Resource Constrained Environments, and Combating Malicious Use of DNS... more

A Few More Thoughts on Email Authentication… errr… Trust

Mike Hammer's thoughtful article, A Few Thoughts on the Future of Email Authentication, should trigger thoughtfulness in the rest of us. Email abuse has been around a long time. Anti-abuse efforts have too. Yet global abuse traffic has grown into the 90+% range, with no hint of trending downward. The best we hear about current effectiveness is for last-hop filtering, if you have the money, staff and skills to apply to the problem... more

Is It Time to Supplement Desktop Security Protections?

Internet users are acutely aware of their exposure on the Internet and clearly concerned about their safety. Increased downloads of scareware as Conficker made headlines in the mainstream media are only the latest evidence. Desktop software is often viewed as a one-stop shop for fighting Internet threats such as viruses, worms and other forms of malware and phishing. These solutions have served us well but more protections are needed to address the dynamic and increasingly sophisticated web based exploits being launched... more

A Few Thoughts on the Future of Email Authentication

With the Online Trust Alliance Town Hall Meeting and Email Authentication Roundtable next week as well as the RSA Conference, I decided to pause and think about where we are and where we might be headed with regard to email authentication. Over the years, many of us have collectively worked to provide a framework for authenticating email... more
