ICANN 35: What’s Going Down, Down Under (Want the Low Down?)

As I've been getting ready to catch my plane for ICANN 35 (Sydney), I can't help but thinking that there are a lot of things going down these days that will dramatically affect makeup of the Internet for years to come. Next year at this time, the root could be a very, very different place. A few of the items that will be getting deconstructed, discussed, debated Down Under are outlined below... more

Google Reveals Top 10 Malware Sites From Its Index

While scanning its index, Google in the last two months reports to have found more than 4,000 different websites suspected of distributing malware by massively compromising popular websites. "Of these domains more than 1,400 were hosted in the .cn TLD. Several contained plays on the name of Google such as goooogleadsence.biz, etc.," says Google's security team member, Niels Provos, in a blog post today. more

How a Resilient Society Defends Cyberspace

Seventy-five years ago today, on May 29th, 1934, Egyptian private radio stations fell silent, as the government shut them down in favor of a state monopoly on broadcast communication. Egyptian radio "hackers" (as we would style them today) had, over the course of about fifteen years, developed a burgeoning network of unofficial radio stations... It couldn't last. After two days of official radio silence, on May 31st, official state-sponsored radio stations (run by the Marconi company under special contract) began transmitting a clean slate of government-sanctioned programming, and the brief era of grass-roots Egyptian radio was over... more

Obama: From Now On Digital Infrastructure Treated As Strategic National Asset

In a speech today from the White House, President Obama declared that the United States' computers and digital networks are strategic national assets and that he will personally appoint a cybersecurity coordinator to oversee the effort to protect this critical infrastructure. more

Survey Finds “Complexity” as Most Common Challenge in Deploying DNSSEC

According to a recent survey conducted by the European Network and Information Security Agency (ENISA), 78% of service providers in Europe have plans to deploy DNSSEC within the next 3 years. On the other hand, the study also found 22% have no plans to deploy DNSSEC in the next 3 years. more

Hannaford Data Breach Plaintiffs Rebuffed in Maine

A US District Judge in Maine largely granted a motion to dismiss brought by Hannaford in a big data breach case... According to the court, around March 2008, third parties stole up to 4.2 million debit and credit card numbers, expiration dates, security codes, PIN numbers, and other information relating to cardholders "who had used debit cards and credit cards to transact purchases at supermarkets owned or operated by Hannaford." more

Securing a Cloud Infrastructure

George Reese (author of the new book Cloud Application Architectures: Building Applications and Infrastructure in the Cloud) is talking at Gluecon about securing cloud infrastructures. Two recent surveys found "security" was the number one concern of companies considering a move to the cloud. George says the key to making customers comfortable with cloud security is transparency... more

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

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

Rustock, Xarvester Spambots Capable of Sending 25,000 Messages Per Hour, Says New Study

A recent study suggests Rustock and Xarvester malware provided the most efficient spambot code, enabling individual zombie computers to send 600,000 spam messages each over a 24 hour period. "Over the past few years, botnets have revolutionized the spam industry and pushed spam volumes to epidemic proportions despite the best efforts of law enforcement and the computer security industry. Our intention was to better understand the origins of spam, and the malware that drives it," said Phil Hay, senior threat analyst, TRACElabs (a research arm of security company Marshal8e6)... 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

Implications of California Telecom Attack Gone Un-Reported

In an article titled "A Cyber-Attack on an American City", Bruce Perens writes: "Just after midnight on Thursday, April 9, unidentified attackers climbed down four manholes serving the Northern California city of Morgan Hill and cut eight fiber cables in what appears to have been an organized attack on the electronic infrastructure of an American city. Its implications, though startling, have gone almost un-reported. That attack demonstrated a severe fault in American infrastructure: its centralization. The city of Morgan Hill and parts of three counties lost 911 service, cellular mobile telephone communications, land-line telephone, DSL internet and private networks, central station fire and burglar alarms, ATMs, credit card terminals, and monitoring of critical utilities..." 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
