Are You Getting Your News From Spam? My Mother Does

This is a story about my mother and Obama. My mother: "Have you heard about Obama? Really impressive guy." Me: "What about him?" My mother: "x, y and z." Me: "Where did you hear about this?" My mother: "I read email too, you are not the only one who is into technology." Luckily, my mother bases her opinion on more than just spam messages...

Peering into Fast Flux Botnet Activity

Together with Thorsten Holz, I recently published a paper on fast flux botnet behaviors, "As the Net Churns: Fast-Flux Botnet Observations," based on data we gathered in our ATLAS platform. Fast flux service networks utilize botnets to distribute the web servers to the infected PCs... One of the most well known fast flux botnets has been the Storm Worm botnet, which uses the zombies to spam, send out new enticements to infect users, and to host the malicious website which delivers the malcode.

Time for Self Reflection

In case you don't read any of what I have to say below, read this: I have dual citizenship. Along with my homeland citizenship, I am of the Internet, and see it as my personal duty to try and make the Internet safe. Atrivo (also known as Intercage), is a network known to host criminal activity for many years, is no more. Not being sarcastic for once, this is the time for some self reflection.

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...

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...

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...

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.

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.

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.

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.
