Botnets and their spam output

Source: Marshal TRACE Blog

Marshal has released spam statistics for February 2008, showing a breakdown by source botnet. Of note is the fact that botnet size and spam quantity output are not closely related. Although the Storm botnet is renowned for being quite large, it was responsible for only 2% of spam for the month. Contrast this with the Srizbi botnet, which was responsible for nearly 40%.
