This in from F-Secure’s blog: paint that defends against leaking wireless data at forcefield wireless. Probably some cheap additive that painters have known about for years, but an interesting (and fun) marketing campaign nevertheless. I’ve often thought there would be a market for tinfoil clothing to protect against all the wireless transmissions and emissions coarsing through our bodies all the time.
