I'm new here, but I've enjoyed this topic for awhile. Not sure if any have you have read about this, but it's pretty interesting. Almost controversial in my opinion.
Botnets, networks of malware-infected machines that are controlled by an adversary, are the root cause of a large number of security threats on the Internet. A particularly sophisticated and insidious type of bot is Torpig, a malware program that is designed to harvest sensitive information (such as bank account and credit card data) from its victims.
At the beginning of 2009, we took control of the Torpig botnet for ten days. Over this period, we observed more than 180 thousand infections and recorded more than 70 GB of data that the bots collected.
Here's the original article that lead me to find the research study. Their presentation is listed as well. http://www.catonmat.net/blog/how-to-steal-...t=Google+Reader
