Sniffing is a powerful tool in the hands of a hacker.
Network sniffers examinie network traffic but not alter it.
The Sniffer program works by asking a computer,
specifically its Network Interface Card (NIC), to stop
ignoring all the traffic headed to other computers and pay
attention to them. It does this by placing the NIC in a
state known as promiscuous mode. Once a NIC is promiscuous
mode, a machine can see all the data transmitted on its
segment. The program then begins to constantly read all
information entering the PC through the network card. Data
traveling along the network comes as frames, or packets,
bursts of bits formatted to specific protocols. Because of
this strict formatting, the sniffer peels away the layers
of encapsulation and decodes the relevant information
stored in the packet sent, including the identity of the
source computer that of the targeted computer, and every
piece of information exchanged between the two computers.
