Free Wi-Fi is becoming increasingly commonplace — millions of us connect to it every day — but are these connections secure?

TODAY's Tom Costello turned to cyber-security experts, who demonstrated just how easily criminals can take control of devices that are connected the wrong Wi-Fi hotspots. Their advice:

  • Know who is behind the hotspot you're connecting to.
  • Use a secure Wi-Fi whenever possible.
  • Keep your security software up to date.
  • Use Web filtering to block malicious code or phishing expeditions.

Cyber security is opportunistic, so it's always best to be on your guard, especially when on a network you're not sure you can trust.
