Botnet Statistics [2009-12-17]

I should write some scripts to automatically combine numbers from both detection systems. Manual calculation is error-prone. Taiwan's numbers are taken from the new detection system, while other countries' numbers are taken from the old one.

detection period: 2009-12-17 00:00-23:59 UTC
total number of suspected botnet IPs: 3477
number of botnet IPs notified to network operators: 3266

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

Rank	Network	# of suspected botnet IPs
1	HINET-NET	1024
2	APOL-NET	593
3	TFN-NET	307
4	BSNLNET	218
5	CHINANET-GD	140
6	002.558.157/0001-62	91

8	RCOM	42
9	UNICOM-SD	38
10	002.558.134/0001-58	32

The top 10 countries (as defined by the 2-character country code), ordered by number of suspected botnet IPs are:
