Srsly Risky Biz: It Is Time to Ban Sale of Precise Geolocation

A recent deep dive into the American adtech surveillance system, Webloc, highlights the national security and privacy risks of pervasive and easily obtainable geolocation data. It brings home, once again, that the US needs to clamp down on the collection and sale of geolocation data.
The report, from Citizen Lab, documents what Webloc says it can do, who uses the product and its relationship with other commercial intelligence products.
Webloc was developed by Cobweb Technologies, but is now sold by the US firm Penlink after the two companies merged in 2023. A leaked technical proposal document, obtained by Citizen Lab, says that Webloc provides access to records from "up to 500 million mobile devices across the globe". These records contain device identifiers, location coordinates and profile data from mobile apps and digital advertising.
