* Do not have work-related emails on your Android (unless it's Google-made). iOS (9+) is okay. * Do not open random attachments on a Windows machine. (We always do our best to convince them to switch to a Ubuntu station with an AppArmor profile for LibreOffice set.)
This is a good start. I think this article would be even better if it included some phishing tips (like HTTPS doesn't automatically mean "secure", and if you're suddenly logged out of Google for no apparent reason, don't just log into the webpage displayed to you, but instead, open Google by typing the address bar manually and log in there).
Interesting side-note: Asshats spend days crafting phishing emails specifically targeted to our journalists, and they never get Google's postal address right in the footer.
