DNSSEC Rally

In late August the White House mandated that all of the agencies in the US government have functioning DNSSEC capabilities deployed and operational by December 2009. I am suggesting here that we, as a community, commit to the same timetable. I call upon VeriSign and other registries to bring up DNSSEC support by January 2009. more

Estonian Cyber Security Strategy Document: Translated and Public

The Estonians have a public version of their cyber security strategy translated into English (currently available offline only). The concept of a national strategy for cyber security is one which I am particularly fond of... The following is the Summary section from the document which might be of interest... more

IGF Meeting Blacklisted

I got an e-mail from someone currently attending the Internet Governance Forum (IGF) meeting in Geneva. The e-mail ended up in my spam folder because the IP address used for the wireless LAN at the meeting is on a spambot/virusbot blacklist, namely cbl.abuseat.org. Apparently some guy there has his computer infected by a spambot or a virusbot... more

Caring About Cybersecurity or Preparing the Ground for an I-Patriot Act?

Few months ago in a talk given at the Institution of Engineering and Technology organised here in London by the Society for Computers and Law, Professor Lessig recounted a conversation he had with former US Counter Terrorism Czar Richard Clarke, where Larry asked the question that many had in mind... how the US Government managed to conceptualize, design and draft a piece of legislation as vast and complex as the USA PATRIOT Act in such a short period of time (a month and 15 days after 9/11), and the answer was what many people had imagined... more

Cyber Crime: An Economic Problem

During ISOI 4 (hosted by Yahoo! in Sunnyvale, California) whenever someone made mention of RBN (the notoriously malicious and illegal bulletproof hosting operation, the Russian Business Network) folks would immediately point out that an operation just as bad was just "next door" (40 miles down the road?), working undisturbed for years. They spoke of Atrivo (also known as Intercage). The American RBN, if you like... more

Public Sharing and a New Strategy in Fighting Cyber Crime

A couple of years ago I started a mailing list where folks not necessarily involved with the vetted, trusted, closed and snobbish circles of cyber crime fighting (some founded by me) could share information and be informed of threats. In this post I explore some of the history behind information sharing online, and explain the concept behind the botnets mailing list... we may not be able to always share our resources, but it is time to change the tide of the cyber crime war, and strategize. One of the strategies we need to use, or at least try, is public information sharing of "lesser evils" already in the public domain. more

Thoughts on the Best Western Compromise

The Sunday Herald reported on Sunday that Best Western was struck by a trojan attack that lead to the possible compromise of about 8 million victims. There is some debate as to the extent of the breach and not a small amount of rumor going around. I'm not entirely disposed to trust corporate press releases for the facts, nor am I going to blindly accept claims of security researchers whose first call is to the PR team when discovering a problem. That said, here is what seems to be the agreed upon facts... more

Mobilizing Russian Population Attacking Georgia: Similar to the Estonian Incident?

It seems like the online Russian population is getting mobilized. Like a meme spreading on the blogosphere, the mob is forming and starting to "riot", attacking Georgia. This seems very similar to the Estonian incident, only my current guess is natural evolution rather than grass-roots implanted -- but I am getting more and more convinced of the similarities as more information becomes available. Determining exactly when the use of scripts by regular users started, is key to this determination. more

A Secure Recursive Caching DNS Server

Over the last couple of weeks I have spent some time working on a project to develop a DNS cache for Windows that is intended to be reasonably secure against spoof attacks, in particular in situations where NAT firewalls may prevent port randomization. The program is evolving, but currently uses a couple of ideas to attempt to defeat spoof attacks... The source code is intended to be entirely un-encumbered, that is free in all respects. I would welcome any suggestions or comments on the aims of the project, the source code, the functionality of the program or other ideas. more

Trust, but Verify

We are at an inflection point in our lifetimes. The Internet is broken, seriously broken... Almost all of the systems currently in use on the Internet are based on implicit trust. This has to change. The problem is that these systems are so embedded in our everyday lives that it would be, sort of like, changing gravity, very difficult. more
