    Amazon devices will soon automatically share your Internet with neighbors

    Hidden Content
    If you use Alexa, Echo, or any other Amazon device, you have only 10 days to opt out of an experiment that leaves your personal privacy and security hanging in the balance.

    On June 8, the merchant, Web host, and entertainment behemoth will automatically enroll the devices in Amazon Sidewalk. The new wireless mesh service will share a small slice of your Internet bandwidth with nearby neighbors who donít have connectivity and help you to their bandwidth when you donít have a connection.By default, Amazon devices including Alexa, Echo, Ring, security cams, outdoor lights, motion sensors, and Tile trackers will enroll in the system. And since only a tiny fraction of people take the time to change default settings, that means millions of people will be co-opted into the program whether they know anything about it or not. The Amazon webpage says Sidewalk "is currently only available in the US."

    What is Amazon Sidewalk?
    Amazon Sidewalk is a shared network that helps devices work better. Operated by Amazon at no charge to customers, Sidewalk can help simplify new device setup, extend the low-bandwidth working range of devices to help find pets or valuables with Tile trackers, and help devices stay online even if they are outside the range of their home wifi. In the future, Sidewalk will support a range of experiences from using Sidewalk-enabled devices, such as smart security and lighting and diagnostics for appliances and tools.

    How will Amazon Sidewalk impact my personal wireless bandwidth and data usage?
    The maximum bandwidth of a Sidewalk Bridge to the Sidewalk server is 80Kbps, which is about 1/40th of the bandwidth used to stream a typical high definition video. Today, when you share your Bridgeís connection with Sidewalk, total monthly data used by Sidewalk, per account, is capped at 500MB, which is equivalent to streaming about 10 minutes of high definition video.

    Why should I participate in Amazon Sidewalk?
    Amazon Sidewalk helps your devices get connected and stay connected. For example, if your Echo device loses its wifi connection, Sidewalk can simplify reconnecting to your router. For select Ring devices, you can continue to receive motion alerts from your Ring Security Cams and customer support can still troubleshoot problems even if your devices lose their wifi connection. Sidewalk can also extend the working range for your Sidewalk-enabled devices, such as Ring smart lights, pet locators or smart locks, so they can stay connected and continue to work over longer distances. Amazon does not charge any fees to join Sidewalk.Amazon has published a white paper detailing the technical underpinnings and service terms that it says will protect the privacy and security of this bold undertaking. To be fair, the paper is fairly comprehensive, and so far no one has pointed out specific flaws that undermine the encryption or other safeguards being put in place. But there are enough theoretical risks to give users pause.Bluetooth has had its share of similar vulnerabilities over the years, too, either in the Bluetooth standard or in the way itís implemented in various products.
    If industry-standard wireless technologies have such a poor track record, why are we to believe a proprietary wireless scheme will have one thatís any better?

    The omnipotent juggernaut
    Next, consider the wealth of intimate details Amazon devices are privy to. They see who knocks on our doors, and in some homes they peer into our living rooms. They hear the conversations weíre having with friends and family. They control locks and other security systems in our home.Extending the reach of all this encrypted data to the sidewalk and living rooms of neighbors requires a level of confidence thatís not warranted for a technology thatís never seen widespread testing.Last, letís not forget whoís providing this new way for everyone to share and share alike. As independent privacy researcher Ashkan Soltani puts it: ďIn addition to capturing everyoneís shopping habits (from amazon.com) and their internet activity (as AWS is one of the most dominant web hosting services)... now they are also effectively becoming a global ISP with a flick of a switch, all without even having to lay a single foot of fiber.Ē

    Amazonís decision to make Sidewalk an opt-out service rather than an opt-in one is also telling. The company knows the only chance of the service gaining critical mass is to turn it on by default, so thatís what itís doing. Fortunately, turning Sidewalk off is relatively painless. It involves:

    Opening the Alexa app
    Opening More and selecting Settings
    Selecting Account Settings
    Selecting Amazon Sidewalk
    Turning Amazon Sidewalk Off
    No doubt, the benefits of Sidewalk for some people will outweigh the risks. But for the many, if not the vast majority of users, thereís little upside and plenty of downside.

    I think it's in the USA at the moment only, but I would opt out
