Botnet Statistics [2010-03-26]

One of my 2 detection systems, which usually detects more bots than the other, has some problem today. I have not been able to connect to it so far. So the following data were calculated only from the log of the other one.

total number of suspected botnet IPs: 1653
number of botnet IPs notified to network operators: 1420
number of blocked spams: 87331
recipient count of blocked spams: 1315757
