My guess is that everyone on the internet has been subjected to espionage activity. We hear about corporate and government compromises in the news all the time. If my understanding is correct, those compromises happen because hackers routinely search the internet with software that looks for computer systems that are not protected against all possible weaknesses. The sophistication of the hackers ranges from little kids with fat fingers who don’t know any better, to sophisticated organizations sponsored by foreign governments who DO know better, but just don’t care.
Online, we are all subject to contact, even if we are not aware of that contact.
