   There are many ways even air-gapped systems can or do leak data, that   
   may leak the keys or partial information about them.   
      
   IMO every system that exists on the same side of the singularities as we   
   do *is* connected with the rest.  It just may be harder to get the data   
   you want.   
      
   We had leaking CRTs which could be read over a distance, AM leaks using   
   rhythms of loops while computing, blinking drive LEDs, RPM modulated   
   fans, ultrasonic connections between laptops in exams, and additionally   
   we are in the

   era and I definitely will not bet that ARM and RISCV chips or even FPGAs   
   don't come "pre-infected" in a comparable way.  So who knows which   
   Gremlins in other chips are able to play e.g. modem over power-line and   
   whatnot.   
      
   So better assume that every system that is not made exclusively from   
   logic gates[0] you've baked yourself in your kitchen already comes   
   infected with spy hard- and software.  And thinking about this shouldn't   
   stop without a look at the power supply[1].  Some leaks still may exist   
   no matter what you use to build the gates, but at least the foreign   
   gremlins would stay outside.
