Why Your Wi-Fi Router Doubles As an Apple AirTag

An anonymous reader quotes a report from Krebs On Security: Apple and the satellite-based broadband service Starlink each recently took steps to address new research into the potential security and privacy implications of how their services geo-locate devices. Researchers from the University of Maryland say they relied on publicly available data from Apple to track the location of billions of devices globally -- including non-Apple devices like Starlink systems -- and found they could use this data to monitor the destruction of Gaza, as well as the movements and in many cases identities of Russian and Ukrainian troops. At issue is the way that Apple collects and publicly shares information about the precise location of all Wi-Fi access points seen by its devices. Apple collects this location data to give Apple devices a crowdsourced, low-power alternative to constantly requesting global positioning system (GPS) coordinates. Both Apple and Google operate their own Wi-Fi-based Positioning Systems (WPS) that obtain certain hardware identifiers from all wireless access points that come within range of their mobile devices. Both record the Media Access Control (MAC) address that a Wi-FI access point uses, known as a Basic Service Set Identifier or BSSID. Periodically, Apple and Google mobile devices will forward their locations -- by querying GPS and/or by using cellular towers as landmarks -- along with any nearby BSSIDs. This combination of data allows Apple and Google devices to figure out where they are within a few feet or meters, and it's what allows your mobile phone to continue displaying your planned route even when the device can't get a fix on GPS. With Google's WPS, a wireless device submits a list of nearby Wi-Fi access point BSSIDs and their signal strengths -- via an application programming interface (API) request to Google -- whose WPS responds with the device's computed position. Google's WPS requires at least two BSSIDs to calculate a device's approximate position. Apple's WPS also accepts a list of nearby BSSIDs, but instead of computing the device's location based off the set of observed access points and their received signal strengths and then reporting that result to the user, Apple's API will return the geolocations of up to 400 hundred more BSSIDs that are nearby the one requested. It then uses approximately eight of those BSSIDs to work out the user's location based on known landmarks. In essence, Google's WPS computes the user's location and shares it with the device. Apple's WPS gives its devices a large enough amount of data about the location of known access points in the area that the devices can do that estimation on their own. That's according to two researchers at the University of Maryland, who theorized they could use the verbosity of Apple's API to map the movement of individual devices into and out of virtually any defined area of the world. The UMD pair said they spent a month early in their research continuously querying the API, asking it for the location of more than a billion BSSIDs generated at random. They learned that while only about three million of those randomly generated BSSIDs were known to Apple's Wi-Fi geolocation API, Apple also returned an additional 488 million BSSID locations already stored in its WPS from other lookups. "Plotting the locations returned by Apple's WPS between November 2022 and November 2023, Levin and Rye saw they had a near global view of the locations tied to more than two billion Wi-Fi access points," the report adds. "The map showed geolocated access points in nearly every corner of the globe, apart from almost the entirety of China, vast stretches of desert wilderness in central Australia and Africa, and deep in the rainforests of South America." The researchers wrote: "We observe routers move between cities and countries, potentially representing their owner's relocation or a business transaction between an old and new owner. While there is not necessarily a 1-to-1 relationship between Wi-Fi routers and users, home routers typically only have several. If these users are vulnerable populations, such as those fleeing intimate partner violence or a stalker, their router simply being online can disclose their new location." A copy of the UMD research is available here (PDF).

Hubble Network Makes Bluetooth Connection With a Satellite For the First Time

Aria Alamalhodaei reports via TechCrunch: Hubble Network has become the first company in history to establish a Bluetooth connection directly to a satellite -- a critical technology validation for the company, potentially opening the door to connecting millions more devices anywhere in the world. The Seattle-based startup launched its first two satellites to orbit on SpaceX's Transporter-10 ride-share mission in March; since that time, the company confirmed that it has received signals from the onboard 3.5mm Bluetooth chips from over 600 kilometers away. The sky is truly the limit for space-enabled Bluetooth devices: the startup says its technology can be used in markets including logistics, cattle tracking, smart collars for pets, GPS watches for kids, car inventory, construction sites, and soil temperature monitoring. Haro said the low-hanging fruit is those industries that are desperate for network coverage even once per day, like remote asset monitoring for the oil and gas industry. As the constellation scales, Hubble will turn its attention to sectors that may need more frequent updates, like soil monitoring, to continuous coverage use cases like fall monitoring for the elderly. Once its up and running, a customer would simply need to integrate their devices' chipsets with a piece of firmware to enable connection to Hubble's network.

'Smart Devices Are Turning Out To Be a Poor Investment'

An anonymous reader quotes a report from Android Police, written by Dhruv Bhutani: As someone who is an early adopter of all things smart and has invested a significant amount of money in building a fancy smart home, it saddens me to say that I feel cheated by the thousands of dollars I've spent on smart devices. And it's not a one-off. Amazon's recent move to block off local ADB connections on Fire TV devices is the latest example in a long line of grievances. A brand busy wrestling away control from the consumer after they've bought the product, the software update gimps a feature that has been present on the hardware ever since it launched back in 2014. ADB-based commands let users take deep control of the hardware, and in the case of the Fire TV hardware, it can drastically improve the user experience. [...] A few years ago, I decided to invest in the NVIDIA Shield. The premium streamer was marketed as a utopia for streaming online and offline sources with the ability to plug in hard drives, connect to NAS drives, and more. At launch, it did precisely that while presenting a beautiful, clean interface that was a joy to interact with. However, subsequent updates have converted what was otherwise a clean and elegant solution to an ad-infested overlay that I zoom past to jump into my streaming app of choice. This problem isn't restricted to just the Shield. Even my Google TV running Chromecast has a home screen that's more of an advertising space for Google than an easy way to get to my content. But why stop at streaming boxes? Google's Nest Hubs are equal victims of feature deterioration. I've spent hundreds of dollars on Nest Hubs and outfitted them in most of my rooms and washrooms. However, Google's consistent degradation of the user experience means I use these speakers for little more than casting music from the Spotify app. The voice recognition barely works on the best of days, and when it does, the answers tend to be wildly inconsistent. It wasn't always the case. In fact, at launch, Google's Nest speakers were some of the best smart home interfaces you could buy. You'd imagine that the experience would only improve from there. That's decidedly not the case. I had high hopes that the Fuchsia update would fix the broken command detection, but that's also not the case. And good luck to you if you decided to invest in Google Assistant-compatible displays. Google's announcement that it would no longer issue software or security updates to third-party displays like the excellent Lenovo Smart Display, right after killing the built-in web browser, is pretty wild. It boggles my mind that a company can get away with such behavior. Now imagine the plight of Nest Secure owners. A home security system isn't something one expects to switch out for many many years. And yet, Google decided to kill the Nest Secure home monitoring solution merely three years after launching the product range. While I made an initial investment in the Nest ecosystem, I've since switched over to a completely local solution that is entirely under my control, stores data locally, and won't be going out of action because of bad decision-making by another company. "It's clear to me that smart home devices, as they stand, are proving to be very poor investments for consumers," Bhutani writes in closing. "Suffice it to say that I've paused any future investments in smart devices, and I'll be taking a long and hard look at a company's treatment of its current portfolio before splurging out more cash. I'd recommend you do the same."
