Although most people might see this as
a nice opportunity for stealing access to the Internet, the key
consequence for criminals is that all the traf?¬?c generated can be
sniffed without putting a foot in the victim??™s house. The address
of the sites visited, the chat conversation taking place, the documents
downloaded or transferred, the mail read from a Web
interface, the information typed on nonprotected channels, all
can be running like a river on the screen of Eve??™s laptop, in her
car parked not too far from the victim??™s residence.
Again, there are means of countering those threats. websites can
protect their traf?¬?c by using HyperText Transfer Protocol Secure
(HTTPS), more on that in the next sections), and Wi-Fi networks
can count on Wired Equivalent Privacy (WEP) and Wi-Fi
Protected Access (WPA) encryption methods for safeguarding
the privacy of their users. The purpose of this section was to give
you a feel for how easy and remunerative it is for Eve to be the
man in the middle if Alice and Bob do not take adequate precautions.
Attacks in the Information-Storing and -Processing Phases
Let??™s strengthen the hypothesis we assumed at the beginning of
the previous section.
