Botnet Statistics for August 2015

detection period: 2015-08-01 00:00 - 2015-08-31 23:59 UTC
total number of suspected botnet IPs: 38727
number of blocked spams: 1856497
recipient count of blocked spams: 41110718

The vps I use for data file backup disappeared in August, so I lost about 2/3 of the data needed for calculating number of blocked spams and recipient count of blocked spams. That is the reason why they seem to be much less this month.
