While it continued to hold its position as the spam capital of the world with 9.8 percent of spam zombies; it was also the highest source of botnet spam, with 6.6 percent or close to 1.45 billion spams originating from its borders every day.
India ranked especially high in the number of top botnets like Cutwail, Kelihos, GRUM and GHEG. Large botnets like Cutwail and Kelihos have made their presence felt in the threat landscape this year by sending out malicious attachments.
