Sniffing Wireless Packets:
A packet sniffer is a utility that has been used since the original release of Ethernet. Packet sniffing allows individuals to capture data as it is transmitted over a network and is used by network professionals to diagnose network issues, and by malicious users to capture unencrypted data, like passwords and usernames. If this information is captured in transit, a user can gain access to a system or network.
In this tutorial we will use Wireshark for sniffing wireless packets.
