Top infected network blocks for mid-August

Posted by Maxim Weinstein Mon, 25 Aug 2008 14:30:03 GMT

In June we released a report with numbers from late May, showing the network blocks containing the largest numbers of badware sites reported by Google. In July, we released an udpate. Here is another update from mid-August:

# of badware sites AS block name
28520 CHINANET-BACKBONE No.31,Jin-rong Street
8743 BIZLAND-SD – Endurance International Group, Inc.
8043 CHINA169-BACKBONE CNCGROUP China169 Backbone
5452 CHINANET-SH-AP China Telecom (Group)
3961 CNCNET-CN China Netcom Corp.
3464 THEPLANET-AS – ThePlanet.com Internet Services, Inc.
3182 GOOGLE – Google Inc.
2219 NETDIRECT AS NETDIRECT Frankfurt, DE
1896 CRNET_BJ_IDC-CNNIC-AP China Tietong Telecommunication Corporation
1685 SOFTLAYER – SoftLayer Technologies Inc.

Note: A network block owner is not always the owner or operator of the infected servers on that block, and our publication of these data is intended to inform and educate, not to assign blame.

Not too many changes from last month. AOL is no longer on the list, apparently following through on their commitment to address the issue that landed them on last month’s list. Google reappears with a few thousand infected sites from their Blogger network, which, as previously mentioned, may be more indicative of aggressive scanning and badware removal than it is of threat to the public. Endurance is still high up on the list, though with several thousand fewer infected sites than our last update.
