DDos_Dissector is responsible for summarizing DDoS attack traffic from stored traffic (pcap/flows). The key point is to build a heuristic/algorithm that can find similarities in the analyzed network traffic.
In order to improve software efficiency, we are working on software components that can parse specific DDoS attacks, such as amplification and TCP Syn flood attacks.
- Install the dissector
git clone https://github.com/ddos-clearing-house/ddos_dissector
pip install -r requirements.txt- Provide a pcap to be analized
We do provide some pcap samples. Check the directory pcap_samples. Note, you can provide any type of cap and the size of pcap will influence the processing time. We encourage the use of a medium-size file (25Mbytes to 50Mbytes). You can find other pcap samples online, such as in the this repository.
- Run the software
./ddos_dissector.py -f pcap_samples/sample1.pcap --summary
- Check the generated fingerprint (json file).

-g, --graph build dot file (graphviz). It can be used to plot a visual representation
of the attack using the tool graphviz. When this option is set, youn will
received information how to convert the generate file (.dot) to image (.png).
-f [FILENAME], --filename [FILENAME]
Example: ./ddos_dissector.py -f ./pcap_samples/sample1.pcap --summary --upload
Input file not provided. Use '-f' for that.
