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.",
"description":"Tofsee, also known as Gheg, is another botnet analyzed by CERT Polska. Its main job is to send spam, but it is able to do other tasks as well. It is possible thanks to the modular design of this malware – it consists of the main binary (the one user downloads and infects with), which later downloads several additional modules from the C2 server – they modify code by overwriting some of the called functions with their own. An example of some actions these modules perform is spreading by posting click-bait messages on Facebook and VKontakte (Russian social network).",
