Study: Uptick in spam-sending zombie PCs in September | Software
Compromised computers that send spam as part of their regular botnet activity increased dramatically in September, according to a Symantec study (PDF) released Monday. The Symantec report follows a study from MessageLabs also illustrating the increased use of automated spam relays. After seeing a 37 percent drop in botnet-related spam for August, Symantec reported a 101 percent increase in September. The growth appears to be focused in Europe, the Middle East, and Asia, with South Korea experiencing the largest increase at 4,236 percent. It was followed by Kazakhstan (761 percent), Romania (607 percent), Saudi Arabia (555 percent), and Vietnam (540 percent). Compromised PCs sending spam had been part of the background noise until recently, when their usage surged in September.
