David wants to know if he's secure surfing the internet on his mobile device. Leo says that nothing is unhackable, but LTE is encrypted and very secure. A phone can be hacked, even at the radio level, though. It's also possible for someone to spoof his SIM card. But it's too much work for the average hacker. It would have to be a state level attack in order to accomplish it. Wi-Fi is less secure, and if he's relying on WPA2 or any other Wi-Fi connection, it's possible to hack it. But that's not easy, either. Odds are, there's really not all that much to worry about.

Ilya from Los Angeles, CA

Ilya spends a lot of time traveling and wants to know if Remote PC is a good way to access his computer to surf. Leo says you can, but it could be slower than using a VPN. It really comes down to your bandwidth, and what VPN service you're using. You'd certainly be more secure with a remote access product or VPN. But that doesn't mean a host nation won't see what you're doing. They'll at the very least be suspicious as to why you're using an encrypted app. So avoid authoritarian countries when using it. Leo also recommends the Ubakey.
