This was Trustwave's original headline for this little ditty, and we just couldn't pass it up. The number of Wi-Fi hotspots is expected to increase by 350 percent by 2015. Meanwhile, only 18 percent of the users log on to a VPN when accessing public Wi-Fi. The rest do not. Trusting souls are they! But all too often, that trust is misplaced. And, you don't have to go to some anonymous coffee shop or log on to some hot spot that just showed up on your phone in order to get exploited. The FBI recently released an alert to travelers warning about an increase in malware that pops up on hotel Internet connections, claiming to be an application update that you might otherwise take for granted. Beware.
