I have this USB key which I forgot at a friends house. It's contents is entirely encrypted using Truecrypt 7.1a. Now I have it back and am getting a bit paranoid. This friend is alright but you should never trust the devil in anyone right. This friend is mac-based and quite the nerd. He brags about how he hacks iphones and tablets. And even how he spies on his girlfriends iphone. He shows her all these tricks he can do like getting back pictures she thought she deleted or getting access to her pin-guarded phone. My question is, can my USB stick somehow been comprimised. Like it could autimatically install spyware on my laptop now once I plug it in?
