Global Spam Volume on the Decline, Report Shows
The notorious Rustock botnet, for example, virtually disappeared after December 25th. Once the most powerful botnet in all the land, Rustock now accounts for less than 0.5-percent of all the world's spam. Two other big-time botnets, the Lethic and the Xarvester, have also gone mysteriously quiet in recent weeks. So, why did these botnets suddenly stop spamming? No one knows. But, until they start up again, we should all enjoy our (relatively) clean inboxes while we can.
