I'd say EVs are the greatest risk on the list.
I reported the Canada Chinese Computer Association to CSIS in 1998 due to the fact they controlled all IT hardware sales through all the various members businesses and they were a threat to Nortel as well through IP theft.
TechData, Supercom, Canada Computers, etc.
They were also running a myriad of charities and foundations moving money back and forth.
The security risks such imposes, including to our infrastructure and secure areas.
Imagine letting someone into a Tempest Secure Level A facility with a cell phone. Air gap isn't secure either.
Then again, I reported more than a few security issues on bases during my tenure. Its only gotten worse. Lax standards is not limited to fitness and dress.
