The perils of leaving your Wi-Fi unsecured can be plenty. It can even jeopardize a country's security in extreme cases, as appeared to be the case around 18 months back, when Indian cops found that terrorists were using open Wi-Fi networks to send emails to take responsibility for terrorist activities or to issue threats.
The United States leads Europe when it comes to the number of open Wi-Fi access points. According to WeFi, 40% of all hotspots in the States are unsecured compared to only 25% in Europe. But United States trails France in terms of the number of open access points with captive portals, which are used to “moderate the entry of users into unlocked hotspots.” Although it is not uncommon for public hotspots to be open for the sake of convenience, the use of captive portals can help monitor access and prevent misuse to a certain degree.
Nearly one-third of the world's total Wi-Fi hotspots are unsecured, as per WeFi's estimates. WeFi's database of hotspots includes nearly 50 million hotspots, which the company says is around 10% of the total number of hotspots worldwide.
