Communications privacy

Privacy is a major issue in mobile communications. It is so easy for people to eavesdrop on mobile communications -- including cordless phones -- that until recently snoopers could buy off-the-shelf scanners in the US for eavesdropping. Today they can nevertheless buy books or find Web sites that tell them how to build scanners and tell them what frequencies to tune into for the juiciest conversations. An example of a publisher that caters to these snoopers is Index Publishing Group, Inc.

And then there is the wireless Ethernet standard, IEEE 802.11. The protocol itself is badly flawed. Set up a wireless network and you can expect intruders to do whatever they want to you. Read about this problem -- and how to exploit it -- at http://wardriving.com.

However, there is a cornucopia of ways to achieve communications privacy.  See what the hacker world can tell you..
