[转载]Modeling Botnet Propagation Using Time Zones
信息来源：[url]http://www.cs.ucf.edu/~czou/[/url]Time zones play an important and unexplored role in malware epidemics. To understand how time and location affect malware spread dynamics, we studied botnets, or large coordinated collections of victim machines (zombies) controlled by attackers. Over a six month period we observed dozens of botnets representing millions of victims. We noted diurnal properties in botnet activity, which we suspect occurs because victims turn their computers off at night. Through binary analysis, we also conrmed that some botnets demonstrated a bias in infecting regional populations.
