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.

How Can ICANN Improve Institutional Confidence?

This week ICANN held a public consultation in Washington, D.C., where ICANN's President's Strategy Committee (PSC) solicited remarks from a packed audience of intellectual property (IP) lawyers, domain name registrars and other Internet stakeholders on how the organization can improve institutional confidence. No surprise, ICANN's decision to add new generic top-level domains (gTLDs) to the Internet was on many participants' minds.

Comcast is Right, the FCC is Wrong

A fellow named Paul Korzeniowski has written a very good, concise piece on the Comcast action at the FCC for Forbes, Feds And Internet Service Providers Don't Mix. He manages to describe the controversy in clear and unemotional language, which contrasts sharply with the neutralists who constantly use emotionally-charged terms such as "blocking," "Deep Packet Inspection," "forgery," and "monopoly" to describe their discomfort.

Internet Vigilantism

Atrivo (aka Intercage), a Concord, California-based Internet hosting service, disappeared from the Internet for around two days recently. They didn't go bankrupt or suffer a physical catastrophe. Their providers simply shut them down by refusing their traffic. This might very well be the first time in history that the Internet community, a cooperative association of networks with no governing body, has collectively put someone out of business, if only briefly.

Google Chrome: Cloud Operating Environment

Rather than blathering on to the blogosphere about the superficial features of Google's new Chrome browser I've spent some time studying the available material and [re]writing a comprehensive Wikipedia article on the subject which I intend for anyone to be free to reuse under a Creative Commons Attribution 3.0 license rather than Wikipedia's usual strong copyleft GNU Free Documentation License (GFDL). This unusual freedom is extended in order to foster learning and critical analysis, particularly in terms of security.

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.

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...

Is Anti-Virus Dead?

Each SANSFIRE, the Handlers who can make it to DC get together for a panel discussion on the state of information security. Besides discussion of the hot DNS issue, between most of us there is a large consensus into some of the biggest problems that we face. Two come to mind, the fact that "users will click anything" and that "anti-virus is no longer sufficient". These are actually both related in my mind...

Potential Danger Ahead for Registrants: dot-info Abusive Domain Use Policy

ICANN has posted a request by Afilias for a new registry service in relation to "abusive" domains in dot-info. While in general the proposal is motivated by good intentions, the devil is in the details. While most folks (including myself) probably care very little about the .info TLD, my concern is that any bad implementation in .info might be copied or used as a precedent in other more important TLDs, in particular .com run by VeriSign.
