News today arrives about an old scam gaining new life. Airports and other busy area's around the world are being targeted by hackers that turn on Ad-hoc (known as computer to computer) hotspots to lure business travelers into a connection.

One good practice to follow when using ANY "free" hotspot is to subscribe to and use a trusted VPN proxy service, or use your corporate VPN connection, when you check email or access your online bank account.
You should also turn on the Windows Firewall -- or your third party personal firewall of choice -- and block file and printer sharing while traveling.
