David Dagon is a PhD student in the College of Computing at Georgia Institute of Technology. His area of research includes network security, BSD kernel hacking, honeynets, and malware analysis. He has written extensively about malware, including modelling botnet propagation using time zones and the KarstNet active sinkhole. We describe requirements for a malware collection repository. The repository serves as a clearing house for malware samples, as well as analysis provided by members of the clearing house.
