Subject: drone armies C&C report - February/2006
From: c2report () isotf org

Below is an automatically generated periodic public report from the
ISOTF's affiliated group "DA" ("Drone Armies (botnets) research and
mitigation mailing list" / TISF DA) with the ISOTF affiliated ASreport
project (TISF / RatOut).

For this report it should be noted that we base our analysis on the data
we have accumulated from various sources, which may be incomplete.

Any responsible party that wishes to receive reports of botnet command
and control servers on their network(s) regularly and directly, feel
free to contact us.

In the past few months we did not publish this report, allowing for
responsible parties to ask for regular reports from us on suspected
botnet C&C activity on their networks. As you can see below, the
Internet drastically changed its face positively because these reports
(compared to when we started), and now a lot more so due to direct
reporting.

For purposes of this report we use the following terms:
open    the host completed the TCP handshake
closed    No activity detected
reset    issued a RST

This month's survey is of 4271 unique domain with port or IP with port
suspect C&Cs. This list is extracted from the BBL which currently has a
historical base of 7780 reported C&Cs. Of the suspect C&Cs surveyed, 685
reported as Open, 3353 reported as closed and 572 issued resets to the
survey instrument. Of the C&Cs listed by domain name, 1847 are mitigated
via remapping.


Top 20 ASNes by Total suspect domains mapping to a host in the ASN.
These numbers are determined by counting the number of domains which
resolve to a host in the ASN.  We do not remove duplicates and some of
the ASNs reported have many domains mapping to a single IP.  Note the
Percent_resolved figure is calculated using only the Total and Open
counts and does not represent a mitigation effectiveness metric.
