Botnet Statistics [2012-01-19]

I find a massive number of hosts are still sending spam. This phenomenon might not stop until McAfee releases the patch for the loophole in its "Rumor Service."

detection period: 2012-01-19 00:00-23:59 UTC
total number of suspected botnet IPs: 7157
number of botnet IPs notified to network operators: 5383
number of spam blocked: 4930
recipient count of spam blocked: 148862

The top 10 networks (as found in WHOIS), ordered by number of suspected botnet IPs are:
