How Windows 10 Wi-Fi Sense works?

Windows 10 Wi-Fi Sense feature allows

you to share your Wi-Fi password with

your friends or contacts, as well as lets

you automatically connect to networks

that your friends and acquaintances have

connected to in past, even if you don't

know the password.

Now, when those friends are within the

range of your Wi-Fi network, Windows 10

automatically joins the network with that

saved password you just shared with your

friends and logs them in, without

prompting them for a password.

Enabled by Default, but It's not the actual Security Threat, Here's Why:

Wi-Fi Sense feature is enabled by default

in Windows 10 to make it easier for users

to receive instant access to the Shared

Networks by their Friends or Contacts.

But, But, But… did you notice that the

feature says "For networks I select..."?

"Enabled by default" doesn't mean your

Wi-Fi passwords are automatically going

to be shared with your Facebook or Skype

contacts by default, unless you won’t

manually configure your Wi-Fi Sense

settings to share selected network access

with any contact group.

Under "For networks I select..." option,

you can explicitly control which group of

contacts from which social networks get

access to which Wi-Fi Network.

Until or unless you do not offer your Wi-Fi

password to Wi-Fi Sense, it will not let

selected contact group to connect to your

network.

This means Wi-Fi password sharing

option is OFF for every social network

by default.

And of course even if you choose to share

your Wi-Fi network with your contacts, Wi-

Fi Sense only shares Internet access and

not your actual Wi-Fi password.

Why You Should be Scared of Wi-Fi Sense (Actual Security Threat)

Microsoft promoted Wi-Fi sense as:

In simple words, now you don't need to

read out loud your Wi-Fi password,

character by character when your friends

are at your home and want to use The

Internet. So similarly, you don’t need to

shout across the office or your friend’s

house "What’s the Wi-Fi password?"

However:

"If you choose to share with your

Facebook friends, any of your Facebook

friends who are using Wi-Fi Sense on a

Windows Phone will be able to connect to

the network you shared when it's in

range, You can't pick and choose

individual contacts." -- Microsoft FAQ

says.

As a general Internet user, I used to

accept almost every friend request on the

Facebook and also communicate with lots

of people on Skype or Outlook. In short,

the majority of people in my contact list

are whom I don't know personally or

trust.

So, If I can't choose any individual contact

from my list, then enabling "Network

password sharing feature" will share my

network access with all my contacts in the

selected social network.

Microsoft also Argued:

Neither it allows anyone to access your

local resources so that nobody can hunt

through your personal files.

However, We know that...

The biggest threat of sharing your Wi-Fi

access with everyone on a list is just like

you are allowing hackers to position

themselves between you and the

connection point i.e. Man-in-the-Middle

attack.

In such attack scenarios, the hacker can

access every piece of information you're

sending out on the Internet, including

important emails, account passwords or

credit card information.

Sitting on the same network, an attacker

can also target your machine directly

using Metasploit or any other hacking

tool.

Ultimately, Windows 10 Wi-Fi Sense

probably is not the most secure feature in

the world, but it is not that bad either, if in

future, Microsoft could allow Windows 10

users to choose individual contacts from a

group.

For Now… Should You Stop Using It?

Like many things in life, we have to make

a choice between things that make our

life comfortable and that provide us

absolute security.

AND, if you are concerned more about

security, just turn Wi-Fi Sense OFF.
