You believed air gaps and Faraday cages are bulletproof ways to isolate sensitive systems and data from attackers?

Wrong. [Read all about the attacks](https://www.infosecurity-magazine.com/news/air-gaps-faraday-cages-cant-deter/) documented by Ben-Gurion University -- one awesomely named "Magneto" -- that exploit the low-frequency magnetic radiation of CPUs to transfer data.

The Geek Factor is sky high with this one. I want to validate it in my under-construction Faraday cage pictured below (hardware courtesy of Home Depot).

Are your business systems and mission-critical data as secure as you think?
