QUOTE: Microsoft’s Digital Crimes Unit expanded its legal arsenal against malicious botnets this past weekend when – in collaboration with financial services industry members – it took out servers belonging to ZeuS botnets. Microsoft filed with the U.S. District Court for the Eastern District of New York on March 23rd. The successful application allowed Microsoft and its partners to do a coordinated seizure of some of the worst known Zeus C&Cs.
