Businesses consider installing Faraday cages to cut down on computer microwave or wireless attacks; would home users be next?


Steve Lohr has a Business Day article in the New York Times today, Jan. 18, “Companies fight endless war against computer attacks,” web URL link here. The print version has a humorous intro: “The Lock that Says ‘Pick Me’” – with a bump key.

Some of the newest malware turns on and off cell phone cameras or webcams, for spying. The article discusses the idea of businesses building Faraday cages to stop drive-by wireless or cell phone spying. Now, Faraday cages have been developed for the military, government and large businesses, to protect infrastructure from possible EMP (electromagnetic pulse) or microwave attacks (optical data is not affected, just magnetic). From the article, it sounds feasible that computer manufacturers like Dell could consider designing and manufacturing smaller cage like devices to protect home or small business users.


Popular Science had written about Faraday Cages back in September 2001, just before 9/11.

Picture: Jupiter, at least, is well protected by its electromagnetic fields.

Update: Jan 19

I've noticed that whenever I turn on my repaired XP computer, Kaspersky checks for updates and updates (through Internet) immediately. In my experience, neither mcAfee nor Webroot Spysweeper are as consistent in doing this so promptly.
