Be aware when using public WiFi.
Public WiFi in places like coffee shops and hotels is more susceptible to mobile attacks, so limit the personal information you share (e.g., personally identifying information) and the type of activities you do (e.g., banking) online while using public WiFi.
Keep devices in your possession.
When traveling (especially internationally) don’t let your devices out of your sight. If a device is out of your possession for a significant amount of time, be aware that your information may be compromised.
Double-check to see where your account is logged geographically.
Facebook provides this option, for example. If you see you’ve logged in on the other side of the world, your account has been compromised and you’ll need to reset your password(s) and notify your contacts.
