Make sure to use a VPN on public Wi-Fi. Even though most sites have HTTPS, which prevents most attacks, a few are still possible. The two most common would be:  
  
Man in the Middle – which, contrary to popular belief, is not completely prevented by HTTPS.  
  
Session hijacking – which is basically stealing your cookies.  
  
I have had multiple friends already who have fallen specifically to session hijacking.  
  
Session hijacking is an especially scary attack as it is not prevented by using two-factor authentication.
