= 1 and a Threat Intelligence Analyst for Palo Alto Networks Unit 42, I often use Wireshark to review packet captures (pcaps) of network traffic generated by malware samples.

Filter by IP address: displays all traffic from IP, be it source or destination Bellow is a list of the most common type of filtering. The filtering capabilities are very powerful and complex, there are so many fields, operators and options and their combination becomes overwhelming. Fortunately, wireshark has display filters so that we can search for specific traffic or filter out unwanted traffic, so that our task becomes easier.

Wireshark takes so much information when taking a packet capture that it can be difficult to find the information needed.
