I created an account while in the store with an email of [email protected] and a basic password and surprisingly didn't have to verify the email. Then turned on a VPN to my house.
I plan on just creating a new account every time I go in just to fill up their database with nonsense.
You do realize that they are actually tracking the device itself by the hardware MAC address and other device fingerprints.
The email is just a bonus to let them legally spam you. Anti-spam laws have an exemption. If there's a prior business relationship like shopping in their stores, they can put you on their spam list unless you opt out.
Bogus email only helps for spam but doesn't do anything about tracking.
EDIT: For Android when there's a Captive Portal like the screen shot. devices will use Persistent randomization which while not the hardware MAC will remain the same for the same network where they can track your visits.
That data isn't nothing, either. Over ten years ago, Target was able to use shoppers habits to determine when women were pregnant, sometimes even before the women knew.
I remember febreeze coming out and being like, that would be cool but you can't trust ads and it sounds like total BS. I knew they added a scent, but I had not idea about the subtle social manipulation that they used to shift people's habits.
Speaking of habits, this is the first time I have heard about all the science involved in studying and breaking them.
Thank you for that link. Definitely going to save it.
At least they're telling you. There's also a lot of hidden surveillance in stores - they've done it with Bluetooth and cameras for some time. Things like monitoring how long you look at products and evaluating your reactions to displays.
That's why I always introduce a good bit of entropy to my shopping patterns:
-Enter and go straight to produce
-Spend 20 minutes examining eggplants
-Walk up and down 5 aisles pausing exactly the square of the aisle number in seconds.
-Grab a box of tampons
-Grab what I need as quickly as possible
-Return tampons
-Checkout and leave
Somewhere a marketing team is spending hours trying to figure out how to improve the conversion rates for tampons and eggplants for customers in my demo.
Don't forget to flick and knock on various fruits and vegetables. Randomize how many flicks/knocks per item, and throw in a few on produce items that normally don't get that kind of test e.g. grapes or potatoes.
When you need service, but data is blocked by all the steel in the ceiling/roof. I've used it, but with my VPN active. I wonder if they're now going to try to block VPN services?
In the EU they already had a complaint, because it violates GDPR, but in any case I would never use a public WiFi without a VPN, and even less in places with these conditions, there is also free WiFi in some Rstaurants (even in most McDonalds), public Libraries and others. Fuck surveillance advertising
There's just no reason to unless you are really skimping on phone data. Random wifi hotspots are one of the most dangerous things for an average joe in terms of infosec.
I have seen it on Europe... maybe there was some way to circumvent it hidden away, not sure. But you could type a random email and that's it, like they don't send anything to confirm the email or anything once you submit you have access to internet.
Went to a Walmart the other day and my phone automatically connected to a wifi that was apparently hosted by my cell carrier. Immediately turned on my VPN because wtf. I disconnected at first then realized I didn't have any service at all which was probably why it existed. Thankfully didn't need to log in but that's why I have Firefox relay.
AFAIK it does not exist in Europe, but I meant that these conditions in the EU would not be tolerated. Maybe because of this there isn't a Walmart in the EU, there are a lot of Malls from other companies and none of these use this practices in their restaurants, mostly with free WiFi for their visitors. Offering free WiFi is already enough of a benefit for them, because it attracts customers, they do not need to intrude on their privacy with an obvious attempt to spam them and make money with their data.
Why are all you mother fuckers shopping at Walmart. They are a welfare corporation offloading their costs to tax payers because despite making tons of money they pay shit and skirt employee benefits laws by keeping worker hours low and give new employees info on how to get financial aid such as food stamps.
Yeah, this is the thing. Does literally anyone want to go to Walmart? No. Is it the place I can afford? Increasingly, still no. Not sure I can even afford to walk past whatever the good version of a Whole Foods is today, though.
Because all of the other retailers do the same shit only with higher prices. Here in Canada they don't pay their employees any less than the competition, yet their prices are 30-40% cheaper on average.
That extra 40% doesn't result in better working conditions for the employees, it goes directly to the shareholders and bonuses for the C-suite.
I respect the hell out of Walmart because they actually keep their price increases tied to inflation and aren't out there trying to sell a loaf of poverty white bread for $5 or a pack of 4 chicken breasts for $37.
I got some insight from a friend who works at a major supplier for these retail stores in Canada. He said how they manage prices is that when they anticipate a rise in cost they'll jack the price all the way to a future projected target instead of following the current inflationary rate so that they won't need to constantly quote their customers different prices. They don't care because they know it will get passed downstream.
I’d like to hope they mean the VPN they pay for for other… uses. So it’s no extra money, cuz they already are using it at home to download Overwatch VR Porn.
There was an equal sign in between those words. Idk if it's visible on your end but I see it on mine. That being said, the only free vpn I would use is protonvpn. Downside is it's slow and unstable due to using a free plan.
I always give some bs emails in those authentication forms. Mainly because as a client who tries to connect, I do not have internet access, so I cannot verify my email before they give me the access. And when they gave me access, there is no power in the world to make me do that 🤷
I found a script for bypassing captive portals on Linux back in the day...
The full functionality of how it works escapes me at the moment, but essentially it searches the network for a host that possibly already connected through the captive portal and spoofs their MAC address.
This isn't the one I originally found, but its the same principal and a Kali tool, so it may be considered more secure than the original bash script I copied back in the day:
Not sure about this Walmart case but most you can write any email like random letters [email protected] or not even the Gmail part as long as it's a valid looking mail and then works like you don't even have to confirm the email or anything.
Never trust an open network. Even if the company providing isn't doing anything shady, the easy at which MITM (man in the middle) attacked, can be performed means that many insecure (and some secure) networks can be spoofed with a small amount of know-how.
Always make sure your connecting to a safe, secure wifi network, in a place where you expect that network to exist at.
If your phone connects in a place you wouldn't expect it to connect, double check what it's connecting to, and if necessary, disable your wifi.
That mechanism only happens after you connect to it, you have to connect to the wifi in order to download the certificate to connect. And it doesn't apply to all open WI-FI. A someone can still spoof the wifi. The fun part is when they set up their own false "I agree to the usage" pop up page that just steals your data - standardised systems like this are easily spoofed, especially when it comes to open and insecure wifi. They could even send you a bogus certificate that routes all the traffic through their gateway, allowing them to spy on the secure connections.
Try luck with throwaway email + VPN. Although it's possible they'll still be able to identity you if you're the only one using that VPN on your local Walmart. At least they won't be able to see your traffic.
They can use your wifi signal as a beacon by triangulating the signal strength from at least 3 different points. Then they can figure out in which departments you spend the most time, how long you spend in store, heatmaps, which aisles you skip and generic info like what time you visit, which locations you also shop at.
A quick google for "Retail Wifi tracking" brings up mirame.net , where you can see some of the features.
I would suggest to set your phone to flight mode if you see a "free wifi" sign in your shopping mall.
Sometimes these login portals accept any old bogus email or burner account. They were logging your IP anyway so realistically doesnt add any more compromised dafa
I'm gonna assume that by IP you mean MAC address because your IP is something that gets negotiated with the AP when you connect, changes every time you connect and can't really be linked back to your device at a public AP. In that case, the right move is to enable MAC randomization and connect through a VPN if you need to hide who you're talking to or just rely on TLS if you don't care that they know who you're talking to and only need to hide what was said.
I am so happy to live in Sweden. All open WiFi networks here are free to use and requires no email or account (VPN recommended as always, though). Even at grocery stores.
It was very easy to get free WiFi in the US compared to most EU countries I've been in. But here in the EU at least I have cheap data so it's not all bad.
I've never agreed to this, but I might be on Walmart Wi-Fi from a long time ago. Once recently shopping at Walmart in person I got an email to my account saying something really creepy like, "rate your in store purchases" and sent me pictures of each item I bought IN STORE with an invitation to rate each. Also included my real name. This isn't even the email I use for my online pickup orders.
Don't all stores do this, particularly those with membership cards? Isn't one of the main reasons for these cards to track your purchases in exchange for discounts, besides fostering loyalty? All major stores in my area operate like this. If you use scan-and-pay with a smartphone or another device, joining their membership program is mandatory. They monitor what, when, and where you buy, and sometimes even why. I don't understand why this surprises some people.
Walmart is not a membership store. I never scanned a membership card, or put in any code or anything. I walked in with my child, browsed around a little bit, ended up purchasing a water gun and some potted flowers, paid at the self-scan, and walked out. I did use a debit card, but that card shouldn't even be connected with the old account that I got an email for, as the card is years newer than the account.
Many people here suggesting a throwaway email and/or VPN. While this does migitate the impact somewhat, the only proper response is to not use their "service" and deactivate the WiFi fo your phone (else they might be tracking your MAC address).
Walmart has an interesting app where if you're connected to their wifi then the app "transforms" to tell you what's in stock in the store you're connected to. I wish they'd just do something like Home Depot where the site just tells you if X location has an item or not, but alas.
Wait, do they not do that anymore? I used to be able to search on their website for an item and it wold tell me if it's in stock at the store I selected and the aisle it's in if they have it.
Yeah, you can pretty much assume that any random Wi-Fi asking for that information is already doing that. My local mall has one that will accept any old email but it certainly looks like this one wants you to create an actual Walmart account.
Imo, this is part of the problem with lack of privacy in today's world.
People will accept this more than not, without a second thought. This leads to the taking of a little bit more until one day you are left wondering where your privacy went.
From personal experience I've found that an OpenVPN connection routed over port 53 (same as DNS) bypasses their signin screen entirely.
Of course it's been months since I last tried since I rarely go into the store and don't have reception issues when I do. Could be they've patched it since. Still worth a shot.
It sounds to me like they are developing some tools to help map things inside the store. So they can give you directions to things you are looking for maybe. Also with this information they could do something similar to those Amazon stores where you just pick things up and walk out and it charges you automatically.
Not saying you all want to share the info with them. It is invasive. But as an engineer I can see so many cool features I could build with this information.
That's great, unless the store you're in is a giant concrete bunker.
Mobile data barely works in my neighbourhood supermarket; even text-based communication is frequently dicey, but you want to send someone a photo of something as a "should I buy this"? Fuhgeddaboudit.
Why open yourself up to all the nasty of public WiFi for that?
Either you're buying something cheap, so just do it. Or it's something expensive, and in that case a simple quick message isn't really enough. Go out to the parking lot and talk about it, or come back later.
