Hello today I was meeting with a potential client to see if I can make him a website. so I met him at a coffee shop and I went in with my laptop. I have a lot of private information on this laptop and mistake #1 was taking this to the meeting. he wanted me to show him some websites I have made in the past. the internet at the coffeeshop was not working so I connected to his "hot spot". I am not sure what a hot spot is, I am not that technologically up to date, but anyway...he gave me his password and I connected to his hot spot. my questions are: is it possible that he hacked into my computer because I used his hot spot? is it possible for him to steal some files from my laptop? do you see any security issues here?
