d0z.me: the evil URL shortener
I, like many people, have been closely following a lot of the chaos happening around the recent Wikileaks dump, and was particularly fascinated by the DDoS attacks by activists on either side. One tool specifically caught my eye in the midst of the attacks, however: the JS LOIC. The tool works simply by constantly altering an image file's source location, so that the browser is forced to continuously hammer the targeted server with HTTP requests. Not a sophisticated or technically interesting tool by any means, but conceptually interesting in that it only requires a browser to execute one's portion of a DoS attack. While the concept itself is not all that new, it got me thinking about the implications of such browser based DoS attacks. Clearly, it opens the door for the creation of a DDoS botnet without ever having to actually exploit the hosts participating in the network; all that is required is to get some Javascript to run in the participants' browsers.

2010 Report on Distributed Denial of Service (DDoS) Attacks - Ethan Zuckerman, Hal Roberts, Ryan McGrady, Jillian York, John Palfrey
Download .PDF
Introduction
Distributed Denial of Service (DDoS) is an increasingly common Internet phenomenon capable of silencing Internet speech, usually for a brief interval but occasionally for longer. In this paper, we explore the specific phenomenon of DDoS attacks on independent media and human rights organizations, seeking to understand the nature and frequency of these attacks, their efficacy, and the responses available to sites under attack. Our report offers advice to independent media and human rights sites likely to be targeted by DDoS but comes to the uncomfortable conclusion that there is no easy solution to these attacks for many of these sites, particularly for attacks that exhaust network bandwidth.
This paper makes recommendations for how independent sites can best mitigate the impact of DDoS.
