Here is an abstract of the introduction chapter of my laurea thesis “The Dorothy Project: inside the Storm” (Feb/2009)
The Dorothy Project is aimed at realizing a fully automated framework for botnet
analyses. The name Dorothy comes from the movie “Twister” directed by Jon de Bont
(1996). In the movie, dorothy is the device used for tracking tornados and for mitigating
their devastating effects. The meaning of the second part of the title “inside the Storm”
is twofold. As in the movie – i.e., the dorothy device must operate inside the tornados the
Dorothy tool must be operated by joining a botnet. Storm was the nickname of one
of the largest botnet discovered on September 2007. Dorothy is an open source software
whose main goal is to permit to increase and share information and knowledge about
botnet diffusion and features. It provides a web interface that permits to analyze data
acquired by Dorothy. Data visualization by means of statistics and graphs are other
important features of the Dorothy framework. Differently from other works, Dorothy
is meant to operate in real-time, always presenting fresh data. Operating in real-time is important
since botnets are a fast-developing technology that requires an equally fast-reporting of
modifications, variants and reconfigurations.
[..] the following step has been
to design the framework. Project requirements and specifications have been stated as the
guidelines for software production according to Dorothy Project goals. Next, the
development of Dorothy has been carried out following the principles of modularity,
simplicity, distributed architecture and platform neutrality. The development language
chosen has been the Unix Bash scripting language that offered a high level of
compatibility and allowed Dorothy to be executed on every POSIX shells.
Dorothy is a suite of nine different modules, each one with a specific task to accomplish
and completely independent from the others. This feature permit users to execute their
modules in different places and times, leveraging on the Dorothy distributed
architecture and design.
