PCAP
Packet Capture or PCAP files record the raw data packets. You can use tools like Wireshark and tcpdump to intercept data from a network interface, which are then stored as pcap
files.
With the network activity stored in these files, we can investigate and anaylze traffic at the packet level.
Sample PCAP files
We can generate our own traffic, but there are free, publicly available pcap
files like here: Netresec 1
