Who Has Taken Over As the Most Prolific Botnet Since Rustock Was Taken Down?

Over at the site V3.co.uk, they have an article up today alleging that since the Rustock takedown two weeks ago, the bagle botnet has moved to take over as the botnet that is responsible for sending the most spam. They have not replaced Rustock's total spam volume, only that they are now the number one spam sending botnet. more

Neelie Kroes, the EU, Cloud Computing, Regulation and Good Ears

In her blog EU Commissioner Neelie Kroes blogs on her stance on cloud computing. In short: this is a good development which the EU will embrace and advocate, but may need regulation in order to ensure a safe environment for industry and individuals in the cloud. Here's some thoughts on that. more

Death of the PKI Dragons?

The recent attack on the Comodo Certification Authority has not only shown how vulnerable the current public key infrastructure is, but also that the protocols (e.g., OSCP) used to mitigate these vulnerabilities once exploited, are not in use, not implemented correctly or not even implemented at all. Is this the beginning of the death of the PKI dragons and what alternatives do we have? more

DNSSEC Deployment Reaching Critical Mass

Less than nine months after the DNS root was signed, the rollout of DNSSEC across the Internet's top-level domains is approaching the tipping point. Thanks to the combined efforts of registries around the world, the new security protocol will soon be available to the majority of domain name registrants in almost a quarter of all TLDs. more

2nd Annual RIPE NCC - LEA meeting: Cooperation Unfolds

On Wednesday 16 March the Serious Organised Crime Agency organised a meeting in London with the RIPE NCC. For the second time law enforcers from the whole world met with the RIPE NCC and RIPE community representatives to discuss cooperation. RIPE NCC staged several very interesting presentations that showed the LEAs the importance of the work done within RIPE and ARIN, the information RIPE NCC has and the relevance of all this to LEAs. Also issues were addressed that can potentially be harmful to future investigations. more

On Mandated Content Blocking in the Domain Name System

COICA (Combating Online Infringement and Counterfeits Act) is a legislative bill introduced in the United States Senate during 2010 that has been the topic of considerable debate. After my name was mentioned during some testimony before a Senate committee last year I dug into the details and I am alarmed. I wrote recently about interactions between DNS blocking and Secure DNS and in this article I will expand on the reasons why COICA as proposed last year should not be pursued further in any similar form. more

COICA and Secure DNS

As a strong proponent of the private right of action for all Internet endpoints and users, I've long been aware of the costs in complexity and chaos of any kind of "blocking" that deliberately keeps something from working. I saw this as a founder at MAPS back in 1997 or so when we created the first RBL to put some distributed controls in place to prevent the transmission of unwanted e-mail from low reputation Internet addresses. What we saw was that in addition to the expected costs (to spammers) and benefits (to victims) of this new technology there were unintended costs to system and network operators whose diagnostic and repair work for problems related to e-mail delivery was made more complex because of the new consideration for every trouble ticket: "was this e-mail message blocked or on purpose?" more

DNSSEC - Let’s Stay the Course!

I don't know about you, but I'm starting to think that DNSSEC being so hot these days is a mixed blessing. Yes, it's wonderful that after so many years there is finally broad consensus for making DNSSEC happen. But being so prominent also means the protocol is taking shots from those who don't want to make the necessary software, hardware and operational modifications needed. And DNSSEC has taken some shots from those who just want to be contrarian. 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
