When using your phone to connect to a public WiFi hotspot, the signal from your device to the WiFi router is easily tapped, monitored, and scanned using cheap, widely available technology. Anyone can do it. Also, without protection, your phone can be "hijacked", held for ransom, and all of the information held on your phone is open to loss and theft. Financial fraud, ID theft, and ransomware over WiFi is becoming as common as any petty street crime and is being compared to the Digital Age's version of a modern pickpocket. Fortunately, advanced IT security technology has become easy to use and affordable, and now anyone can become virtually invisible on WiFis and the internet by using a VPN.
