The main task of this software is to... Wireshark. It is much more common to spoof the MAC address itself, but matching them to their appropriate transmitter and receiver addresses can provide the needed forensic evidence of which devices are involved in a particular communication. After extracting the data, this software divides it onto various sections namely Parameters, DNS, Hosts, and Files. In computer networking, a packet capture is a term for intercepting a data packet that is crossing over a target network. Along with viewing and analyzing the PCAP data, you can also edit PCAP data in one of these analyzers.
