It is a pcap capture with all the traffic (background, normal and botnet)
This pcap file was not made public because it contains too much private information about the users of the network.
This file was captures on the main router of the University network.
Capture with only the botnet traffic. It is made public.
This file was captured on the interface of the virtual machine being infected.
This file has the netflows generated by a unidirectional argus. The labels were assigned as this:
- First put Background to all the flows. - Put LEGITIMATE to the flows that match some filters. - Put Botnet to the flows that come to or from the infected IP addresses
- Infected hosts - 188.8.131.52: Windows XP English version Name: SARUMAN. Label: Botnet. Amount of bidirectional flows: 126 - Normal hosts: - 184.108.40.206 (amount of bidirectional flows: 1614, Label: Normal-V42-Stribrek) - 220.127.116.11 (amount of bidirectional flows: 584, Label: Normal-V42-Jist) - 18.104.22.168 (amount of bidirectional flows: 1040, Label: Normal-V42-Grill) - 22.214.171.124 (amount of bidirectional flows: 98, Label: CVUT-WebServer. This normal host is not so reliable since is a webserver) - 126.96.36.199 (amount of bidirectional flows: 2, Label: CVUT-DNS-Server. This normal host is not so reliable since is a dns server)
Please note that the labels of the flows generated by the malware start with "From-Botnet". The labels "To-Botnet" are flows sent to the botnet by unknown computers, so they should not be considered malicious perse. Also for the normal computers, the counts are for the labels "From-Normal". The labels "To-Normal" are flows sent to the botnet by unknown computers, so they should not be considered malicious perse.
Today we capture the neris bot along with the packets of the whole CTU department. We used an XP virtualbox machine with the 188.8.131.52 public ip address. The first hour of capture was only background and latter we run the malware until 5 minutes before ending. We limited the bandwith of the experiment to 20kbps in the output of the bot.
The bot sent spam, connected to IRC, and use HTTP to do some ClickFraud. The first netflow record of the bot is: 2011-08-10 06:04:24.863 0.000 UDP 184.108.40.206:1025 -> 220.127.116.11:53 INT 0 1 64 1 Botnet Tue Aug 16 13:51:25 CEST 2011 We started the overall capture. Bandwith is 100kBps. "Windows XP English Version" -> 18.104.22.168 (SARUMAN) Bot binary: sogou_explorer_silent_22.214.171.1248_2136.exe bot capture file is: botnet-capture-20110816-sogou.pcap Overall capture file is: capture20110816-2.pcap Tue Aug 16 13:52:53 CEST 2011 We started the VM. Tue Aug 16 13:56:07 CEST 2011 We started the capture and the bot. Tue Aug 16 14:12:17 CEST 2011 We stopped the malware and both pcaps.
These files were generated in the Stratosphere Lab as part of the Malware Capture Facility Project in the CVUT University, Prague, Czech Republic. The goal is to store long-lived real botnet traffic and to generate labeled netflows files.
