Wireless networking hacked to see through walls! (BUT...)

Okay, first the bad news: researchers have found a way to modify wireless networking signal processing so that people outside your home or office can "see" what you are doing right through the building's walls.

But there is also good news: another group of researchers has developed a new kind of paint that blocks wireless networking radio waves! Just coat those same walls with this stuff, and if the paint lives up to its promise you'll be free to do... whatever (and I don't wanna know either).

I could also see a huge market for this paint among those worried about mind control rays...
