February was a bad month for email. Due to a surge in the month of February, spam now accounts for 90% of email traffic according to Symantec. Two botnets, named Grum and Rustock, helped this spam surge by pushing up spam levels 5.5 percent. The Grum botnet came back from a period of plateau to increase activity by 51%. The rise of both botnet systems were linked to activity related to Canadian pharmaceutical spam.
