DNS Resolvers and DNSSEC: Roll Over and Die?

Security is great when all the green lights are shining brightly and everything validates as intended, but what happens when you encounter failure? In this work we examine the behaviour of the DNS when security, in the form of DNSSEC is added, and we look at what happens when things do not happen as intended. What triggered this examination was a sudden increase in the traffic generated by secondary servers for the in-addr.arpa reverse zones in December 2009. more

“Internet Drivers License” - A Short History Lesson

The press, the blogosphere, CircleID - everybody has been discussing Craig Mundie's comment on the need for an "Internet Driver's License". Most of the reaction has been from privacy advocates fearing that this is simply another way to kill anonymity on the Internet. Oh well... that's the usual set of reactions. Now... the fun part is, a driver's license also shows that you have the competence to drive... more

Smart Phishing for Smartphones

A common security prediction for 2010 is the continued rise of malware and phishing attacks on mobile phones. The MarkMonitor Security Operations Center recently detected an interesting twist on this theme involving a popular smartphone and the latest smart technologies used by cybercriminals. In this case, instead of compromising a smartphone to steal its information, cybercriminals used phishing techniques to clone smartphones. more

Domain Name Security Gains Prominence in German-Speaking World

The 2010 Domain Pulse, hosted by SWITCH (the .CH registry) was held in the snowy Swiss city of Luzern. Domain Name Security (DNS) was of particular importance in this year's meeting with DNSSEC being implemented in the root zone in 2010 by ICANN, and by many registries in the next few years. ICANN plan to have all root servers signed with DNSSEC by mid-2010 Kim Davies, Manager, Root Zone Services at ICANN told the meeting, starting with the L root server, then A root server with the last being the J root server as all are gradually signed. more

DNSSEC: Will Microsoft Have Enough Time?

I have previously pointed out the shortcomings of good and user friendly support for DNSSEC in Microsoft's Server 2008 R2. During the period just after I wrote the post, I had a dialogue with Microsoft, but during the last months there has been no word at all. The reason I bring this up again is that more and more Top Level Domains (TLDs) now enable DNSSEC and also the fact that within six months the root will be signed. more

Australia Booting Infected Computers Off Their Networks

The Australian has a good article describing the efforts some of their ISPs are making in an attempt to clean up their act: the government is encouraging ISPs to detect computers on their network that are infected and part of botnets, and to communicate to the customer that their system is compromised... Unless the customer feels a little bit of pain they will not change their ways. more

Protecting Customer Data

There have been a number of reports recently about customer lists leaking out through Email Service Providers (ESPs). In one case, the ESP attributed the leak to an outside hack. In other cases, the ESPs and companies involved have kept the information very quiet and not told anyone that data was leaked. People do notice, though, when they use single use addresses or tagged addresses and know to whom each address was submitted. Data security is not something that can be glossed over and ignored. more

Corporate Espionage in the News: Hilton and the Oil Industry

Is anyone calling espionage by means of computers cyber-espionage yet? I hope not. At least they shouldn't call it cyber war. Two news stories of computerized espionage reached me today. The first, regarding the Oil industry, was sent by Marc Sachs to a SCADA security mailing list we both read. The second, about the hotel industry, was sent by Deb Geisler to science fiction convention runners (SMOFS) mailing list we both read. more

Perhaps It’s Time to Regulate Microsoft as Critical Infrastructure?

My main argument is about the policy of handling vulnerabilities for 6 months without patching (such as the Google attacks 0day apparently was) and the policy of waiting a whole month before patching this very same vulnerability when it first became an in-the-wild 0day exploit (it has now been patched, ahead of schedule). Microsoft is the main proponent of responsible disclosure, and has shown it is a responsible vendor... I simply call on it to stay responsible and amend its faulty and dangerous policies. more

China’s CNCERT Response to Google

Gadi Evron writes: "China responds to Google's accusations on its CNCERT web site, here. Johannes Ullrich just brought this to my attention on Facebook. In short, CNCERT wrote that China is the biggest victim of cyber attacks, and that Google lacks evidence to link the recent attacks to China as the perpetrator. I am certain more details and analysis will become available soon." more

Large Hadron Collider, Nessus, and the InterWebz

CERN put the Large Hadron Collider through some rigorous tests, and apparently at first some of the Siemens manufactured SCADA systems failed. While they are apparently better now, and I am happy to see how serious CERN is about security, this does beg the question... WAIT! You mean it's connected to the Internet? I suddenly don't feel so safe. more

Arbor Networks: Internet Architecture and Operations Facing Perfect Storm

According to the latest Infrastructure Security Report by Arbor Netowrks, the Internet architecture and operations is about to face a perfect storm with the convergence of issues including IPv4 to IPv6 migration, implementation of DNS Security Extensions (DNSSEC) and to 4-byte ASNs (used for inter-domain routing on the Internet). "Any one of these changes alone would constitute a significant architectural and operational challenge for network operators; considered together, they represent the greatest and potentially most disruptive set of circumstances in the history of the Internet, given its growth in importance to worldwide communications and commerce," says the report.

Beyond Domains: What Did We Really Learn in 2009?

The beginning of every year is a time for introspection, an appraisal of the year that was, and planning for the year to come. It is also a time to follow tradition and to recap the biggest news of the year. But by now, I am guessing that we have all read our fair share about the people and events who have impacted the last 12 months... if we take a larger vantage point (than our own relatively small domain name industry), these lessons from 2009 -- in my view -- could teach us all and most importantly, really shape the year ahead. more

Google and China: What Business Are Telcos Really In?

It seems like there's a different headline story about Google every day lately, and there's a lot here that service providers should be paying attention to. The launch of Nexus One around CES earlier this month is especially important for all mobile operators as well as the handset vendors partnering with them. A few days later, we started hearing noise about Google Energy. more

Google, China, and Lawful Intercept

Like many people, I was taken by surprised by Google's announcement about its threatened withdrawal from China in the wake of continued censorship and attacks that appeared to emanate from there. My immediate reaction was quite simple: "Wow". There's been a lot of speculation about just why they pulled out. Some reports noted that Google has been losing market share to Baidu... I don't think, though, that that's the whole story. more
