Digging Through an “Administrative Network Stressor” Provider’s Database
On March 15, 2013, Brian Krebs of Krebs on Security wrote “The World Has No Room For Cowards.” In it, he writes a fascinating story about a DDoS attack against his site and also a physical attack against his person. The part where Krebs’ notes that “… there are strong indications that a site named booter.tw may have been involved in the denial-of-service attack on my site yesterday. For some bone-headed reason, the entire customer database file for booter.tw appears to be available for download if you happen to the [sic] know the link to the archive” stood out to me. booter.tw advertises itself as “The Ultimate Administrative Network Stresser [sic] Tool.”
As a security researcher, getting access to a database dump associated with an incident is always interesting. An earlier version of the Krebs’ article linked to the database file, so the following are some quick bits and pieces I pulled out of it. Here is a geo IP location map of the ‘lastip’ field of the ‘users’ database table. The assumption here is that these are the last login IPs for the 312 users of the service. It is important to note that proxies, VPN services, the Tor network, and other IP anonymizing services come into play here and the IPs might not trace back to a user’s actual physical location.
The ‘attacks’ database table contains attacks from January 23, 2013 to March 15, 2013. There were 48,844 entries. Resolving hostnames and parsing out some junk IPs, close to 11,000 unique IPs were targeted. Here is a geo IP location map of the IPs.
The targeted IPs roughly map into the following organization types.
Assuming the ‘duration’ field is in seconds, the average attack duration was 34 minutes. Here is a breakdown of the different attack types:
This posting was a quick visualization of some of booter.tw’s database data as referenced by Krebs. I am glad that he and his family were unharmed during the associated “SWAT”ing attack and I look forward to reading his updates on this fascinating story.
