LONDON, July 16, 2021 /PRNewswire=KYODO JBN/ --

As of July 2021, there were 116.8 million internet users in Japan [

https://www.statista.com/topics/2361/internet-usage-in-japan/ ], and 92.6% of

people globally connect to the internet through the Wi-Fi on their phones.

However, few know that phone Wi-Fi can reveal person's living location.

"All it takes for someone to find your house location is your Wi-Fi name. There

are public websites like Wigle.net that create heatmaps of Wi-Fi hotspots.

Anybody can simply type your Wi-Fi name into Wigle's search bar and find out

where you live," digital security expert at NordVPN [ http://nordvpn.com/ ]

Daniel Markuson comments.

How does a person's phone reveal the Wi-Fi name?

A phone is continuously looking for trusted Wi-Fi networks. Once a person gets

close to home or work, the device automatically connects to the network it

finds there. This is convenient, but by continually broadcasting these "joining

requests", the phone gives out a lot of valuable information [

https://nordvpn.com/es/blog/wifi-scanning-hack/ ] about it.

Can hackers find out where a person lives?

Having "joining requests" combined with Wigle's data, a hacker only needs a

Wi-Fi name to figure out the user's living location.

"A hacker can stick the scanner under a park bench, under a table at the coffee

shop, or just carry it in his backpack," says Daniel Markuson from NordVPN [

http://nordvpn.com/ ]. "You won't notice it, but the scanner will passively log

all nearby Wi-Fi requests."

How to protect yourself?

As scary as it sounds, Daniel Markuson says that there are ways to protect

yourself, and most of them don't require much technical knowledge.

- Change your phone's Wi-Fi settings or turn it off. Even if your phone is

connected to Wi-Fi network, this doesn't stop it from scanning the area for

other networks. The easiest way to change this is to either adjust your

settings or completely turn Wi-Fi scanning off.  

- Change your Wi-Fi strength. To keep your Wi-Fi from showing up on hotspot

heat maps, you can reduce your Wi-Fi strength. You will get a better signal if

your router is in an open space rather than in your closet, but it doesn't need

to be so strong that your neighbors can use it too.

- Use a VPN on your Wi-Fi router. A VPN can encrypt the traffic on every device

connected to your home Wi-Fi.
