Keep in mind you must understand network traffic fundamentals to effectively use Wireshark. This blog provides customization options helpful for security professionals investigating malicious network traffic.Ī pcap for this tutorial is available here. The default column display in Wireshark provides a wealth of information, but you should customize Wireshark to better meet your specific needs. What makes Wireshark so useful? It is very customizable. As a Threat Intelligence Analyst for Palo Alto Networks Unit 42, I often use Wireshark to review traffic generated from malware samples. This tool is used by IT professionals to investigate a wide range of network issues. *10130* -T fields -E occurrence=f -e ipv6.Wireshark is a free protocol analyzer that can record and display packet captures (pcaps) of network traffic. *10130* -T fields -E occurrence=f -e ip.src | sort | uniq | sort -n | wc Lower counts when only counting the first occurrence of the field in each frame. *10130* -T fields -e ipv6.src | sort | uniq | sort -n | wc
*10130* -T fields -e ip.src | sort | uniq | sort -n | wc ICMP and ICMPv6) include an extra IP header so there are multiple ip.src and ip.dst in the packets. This can be done with tshark pulling the ip.src and ip.dst fields and crunching the output.īe aware that some packets (e.g.
A test capture with IPv4 and IPv6 packets, IPv6 addresses appear in the IPv4 statistics.) The menu items above look like a gui front end to the tshark options:Ĭalculate statistics on IPv4 addresses, with source and destination addresses separated into separate categories.Ĭalculate statistics on IPv6 addresses, with source and destination addresses separated into separate categories. Statistics -> IPv6 Statistics -> Source and Destination Addresses Statistics -> IPv4 Statistics -> Source and Destination Addresses
