MAAZBENMaazben

A new botnet, dubbed Maazben, has also been observed and is also growing rapidly. MessageLabs Intelligence has been tracking the growth of Maazben since its infancy in late May and early June. Its dominance in terms of the proportion of spam has been accelerating in the last 30 days from just over 0.5% of all spam, peaking at 4.5% of spam when it is most active. Currently spam from Maazben accounts for approximately 1.4% of all spam, but this is likely to increase significantly over time, particularly since both overall spam per minute sent and spam per bot per minute are increasing.
