the question highlights how ill-suited the 'spy agencies'​​ are for
conducting asymmetric anything.

Unless they had a Brain inside think of a mechanism and explain it to an
Engineer to propose to a Facilities Security Manager who obtained
confirmation from a Director, they would be vulnerable.

For instance, TEMPEST security - every SCIF has it because inside it was
well documented/implemented.  SEISMIC security - no SCIF*** is isolated
from seismic vibrations modulated with data.  So, to ex-filtrate data, have
those passing circus elephants stomp their feet in predetermined patterns.
 Or make one of those "Dune" style thumpers.  The worms in this case being
.... ?

*** I'm suppose some very few SCIFs are vibration isolated for various
reasons, but not as an exfil channel.
