PCAPs for Testing

Downloading

You can download pcaps from the link above using a standard web browser or from the command line using a tool like wget or curl. Here are some examples.

To download the pcap from https://www.malware-traffic-analysis.net/2020/09/16/index.html using wget:

wget https://www.malware-traffic-analysis.net/2020/09/16/2020-09-16-Qakbot-infection-traffic.pcap.zip

To download a pcap from https://www.netresec.com/?page=MACCDC:

wget https://download.netresec.com/pcap/maccdc-2012/maccdc2012_00000.pcap.gz

tcpreplay

You can use tcpreplay to replay any standard pcap to the sniffing interface of your Security Onion sensor.

so-import-pcap

A drawback to using tcpreplay is that it’s replaying the pcap as new traffic and thus the timestamps that you see in Kibana and other interfaces do not reflect the original timestamps from the pcap. To avoid this, a new tool was developed called so-import-pcap.
