Hi! Thanks for looking! I find many used electronics perfectly usable and agreeable, but my father, who used to be in the army and lives abroad, suggested there's a risk that someone might previouslly install spyware/gain access to your information. I was wondering, can we generally counter this risk? (Above is the important question, below are just thoughts that went with it -What are the chances we'd encounter something like this? (More or less likely in different countries?) -Is risk reduced by buying from a certain type of dealer, type of electronic? (Refurbished, craigslist) -Would taking precautions after buying, address the risks? Are there different types of spyware hard/soft spyware? (What are the most likely route a person doing the nefarious act would take?) -What readings might you suggest for commonfolk who use electronics quite extensively and personally, but don't actually understand the tech they're using (but would like to know how to protect their privacy)? Thank you so much!
