A scorching potato: Hundreds of standard cell apps throughout Android and iOS are allegedly being exploited to reap delicate location information on an unprecedented scale. This information assortment, occurring via the promoting ecosystem, is probably going occurring with out the information of customers and even app builders themselves.
The knowledge comes from hacked information belonging to Gravy Analytics, a location information firm whose subsidiary, Venntel, has beforehand bought world location information to US regulation enforcement businesses. This info was reported by Wired, which collaborated with 404 Media to supply the story.
The info breach has uncovered a sprawling community of apps, starting from standard video games like Sweet Crush to courting apps resembling Tinder and Grindr. It additionally contains delicate classes resembling being pregnant monitoring and spiritual prayer apps.
“For the primary time publicly, we appear to have proof that one of many largest information brokers promoting to each industrial and authorities purchasers seems to be buying their information from the internet advertising ‘bid stream,’ moderately than code embedded into the apps themselves,” Zach Edwards, senior risk analyst at cybersecurity agency Silent Push, instructed 404 Media.
This revelation sheds mild on the world of real-time bidding (RTB), a course of the place corporations bid to position advertisements inside apps. Nonetheless, this technique has a harmful facet impact: information brokers can intercept this course of and harvest the situation information of cell phone customers.
Edwards described this as “a nightmare situation for privateness,” including that “there’s some firm on the market performing like a world honey badger, doing no matter it pleases with each piece of information that comes its manner.”
The dimensions of this information assortment is staggering. The hacked Gravy information contains tens of hundreds of thousands of cell phone coordinates from gadgets in the USA, Russia, and Europe. The checklist of affected apps is in depth, overlaying a variety of classes together with social networks, health trackers, e-mail purchasers, and even VPN apps that customers might have downloaded in an try to guard their privateness.
Though the info breach seems to contain Gravy Analytics, it stays unclear whether or not Gravy collected this location information itself or obtained it from one other supply. The dataset, which dates to 2024, gives a uncommon glimpse into the opaque world of the situation information business.
Gravy Analytics performs a pivotal function on this ecosystem, aggregating cell phone location information from varied sources and promoting it to industrial entities or authorities businesses through its subsidiary, Venntel.

Most app builders and corporations included within the checklist didn’t reply to requests for remark. Nonetheless, Flightradar24 acknowledged in an e-mail that it had by no means heard of Gravy however acknowledged displaying advertisements to “assist hold Flightradar24 free.”
Tinder denied any relationship with Gravy Analytics, whereas Muslim Professional, one of many affected prayer apps, claimed it doesn’t authorize advert networks to gather location information of its customers.
The invention that this information seems to originate from real-time bidding is especially vital. It shifts accountability towards rogue actors within the promoting business and the tech giants that facilitate it.

The FTC has lately taken motion in opposition to related practices. In December, the company banned location information firm Mobilewalla from gathering shopper information “from internet advertising auctions for functions apart from collaborating in these auctions.” The FTC additionally ordered Venntel and Gravy Analytics to delete historic location information and barred them from promoting information associated to delicate areas, resembling well being clinics and locations of worship, besides beneath restricted circumstances.
