“Whether it’s paid or not, whether there’s a password involved or not, nearly all of them are completely unsecure,†he said. “The reason that Wi-Fi hotspots put passwords on their Wi-Fi is not to protect the individual, but rather to limit usage…LAN technology evolved years ago for use within organizations where security was never thought to be a major issue. The result is that most of today’s LANs can be hijacked, and all communication can be easily captured and stored on an unseen laptop.â€
Private Communications Corp., a Connecticut-based digital-security company, reports that more than half of the 24 million Wi-Fi networks thought to exist worldwide are unencrypted, meaning they’re effectively open to anyone within radio range.
That statistic is particularly alarming when juxtaposed with another from the same company: In the United States, an estimated 43 million people use Wi-Fi hotspots to conduct personal or professional business.
Lawson said travelers should be wary even when connecting directly to a local area network, or LAN, offered by, say, a big-name hotel.
