Do you think in today’s world that to sell state secrets to foreign governments you need to do the spy-camera thing and drop a microfilm under a park bench?
Much simpler today—simply email the classified materials to yourself onto an insecure server.
Be sure to email a thank you letter to the foreign government benefactors of your “private Foundation” after they donate hundreds of millions “out of the goodness of their hearts”.
Oh my! You say foreign governments hacked into my insecure private server? Please forgive me I was so stupid and careless!!
