Do you know that an eavesdropper (worse, a hacker) can glean from your computer usage at a coffeeshop, airport, or hotel? When on a Wi-Fi hotspot and your data are not protected it's relatively easy for anyone to sniff sensitive information such as emails, passwords, instant messages, and website logins
It's pretty scary thinking they can capture FTP login credentials and even hijack your accounts on Gmail/Yahoo, LinkedIn, Facebook, twitter and more.
Pretty scary, isn't?
