40% of all spam comes from just one source
. . . and it's not the Hormel plant in Austin, Minnesota.Six bots are responsible for 85% of all spam, according to an analysis by Marshal. The Srizbi botnet is the largest single source of spam - accounting for 39% of junk mail messages followed by the Rustock botnet, responsible for 21% of the spam. Spam coming from the Mega-D botnet was temporarily stemmed after control servers were taken out in mid-February. Somebody hug the people who did that, please! The estimated 35,000 zombie clients associated with the Mega-D botnet were infected with the Ozdok Trojan. After 10 days of inactivity, spam from compromised hosts began flowing again earlier this week, after hackers re-established control. Despite the short offline period, Spam-D accounted for an estimated 11% of junk mail in February. Other active spam botnets include Hacktool.Spammer (AKA Spam-Mailer) and botnets associated with the Pushdo (AKA Pandex) family of malware. The infamous Storm botnet, estimated to have about 85,000 compromised hosts, is thought to be responsible for only 3% of spam. Most of the times, spammers have access to multiple botnets and they have been simultaneously sending spam promoting Express Herbals, a line of male enhancement pills. (almost 70% of spam promotes male enhancement pills) You just can't help wondering what a well-placed JDAM or two could do . . . Posted by: Mike 2008-03-21 |
