We have posted some technical analysis to the mebroot/MBR/Sinowal trojan lately and while we at TrustDefender Labs focus quite heavily on the analysis of the trojans and infection vectors itsself on the client side, Researchers at the University of California looked at the data they received on the server side. This compliments our research quite nicely as it provides hard facts how successful those attacks are and how much data the bad guys actually receive.
