New York Times blog post on how easy it is to eavesdrop on an open Wi-Fi session:
Turns out there was absolutely nothing to it. John sat a few feet away with his PowerBook; I fired up my Fujitsu laptop and began doing some e-mail and Web surfing.
That’s all it took. He turned his laptop around to reveal all of this:
* Every copy of every e-mail message I sent *and* received.
* A list of the Web sites I visited.
* Even, incredibly, the graphics that had appeared on the Web sites I had visited.
None of this took any particular effort, hacker skill or fancy software. Anyone could do it. You could do it.
Nice to see this getting some popular attention.
