App Releases • Pry-Fi v1.01

Pry-Fi v1.01

Requirements: Android 4.0+

Overview: You are being watched...

Retailers, crooks, the government, and others shady individuals are

tracking your movements. Even when your Wi-Fi is turned off, your

phone may be broadcasting information to whomever is in range

which can be used both to track repeated visits to as well as your

exact movements in an area under surveillance.

It's not a big step to couple this to personal information - a retailer

for example, could track your trip to the register and correlate with

your payment information. Now the tracking hardware and software

vendors, the store (or chain) owner, their business partners, they can

now all track where you are every time you come into range of one of

their systems, and fully profile who you are, what you do, your

financials, and your daily patterns!

That is just one example, but there are many uses for tracking you.

Make no mistake, this is happening in the real world today .

Pry-Fi

One solution is shutting off Wi-Fi completely (including the

background network scanning, a setting most people don't know

about), but you would lose benefits like automatically connecting to

known Wi-Fi networks and improved location awareness for your

apps. It also does nothing to help the situation for others.

Pry-Fi will prevent your device from announcing all the networks it

knows to the outside world, but it will still allow background scanning

and automatically connecting to Wi-Fi networks. While you are not

connected to a Wi-Fi network, the MAC address will constantly be

pseudo-randomized, following a pattern that still makes the trackers

think you are a real person, but they will not encounter your MAC

address again. This will slowly poison their tracking database with

useless information.

When you do connect to a Wi-Fi network, unless you specify

otherwise, your MAC address will also be randomized - the same MAC

address will not be used the next time you connect to this or any

other network.

War!

Though of course the companies involved with these trackers claim

they wouldn't use the data maliciously, the possibility is there, and we

all know that if something can be abused, ultimately it will be. There

do not appear to be any laws against these practices yet, nor is it

likely Wi-Fi will be redesigned any time soon to get rid of the

information leaks.

But we can make an effort to reduce the usefulness of the tracking

data for the exploiters. Pry-Fi comes with a War mode, which when

enabled tries to make your Android device appear like dozens of

people. Just wandering around an area under Wi-Fi location

surveillance for a few minutes can ruin the tracking data for the

period of your stay.

Proof of Concept

This is proof-of-concept code, and how for it will go in the future

depends on interest and how well it works. It has been tested on

several devices and seems to work, but it is very young still. The

magic the app does to achieve its purpose is ever subject to changing

Android security policies and OEM customizations, so even though it

works now, there really is no saying if it will still be possible in future

firmwares.

Of course you should also keep in mind that tracking can be done in

many ways, and these W-Fi signals are far from the only method in

use.
