This is a 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. 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 5187 unique, domains (or IPs) with port suspect C&Cs. This list is extracted from the BBL which has a historical base of 14723 reported C&Cs. Of the suspect C&Cs surveyed, 678 reported as Open, 1769 reported as closed, and 812 issued resets to the survey instrument. Of the C&Cs listed by domain name in the our C&C database, 5845 are mitigated. 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.
