A recent data breach has revealed that over 12,000 apps have compromised personal information, exposing sensitive location data of users. The breach stemmed from Gravy Analytics, a data broker that collects and sells location data, which was hacked, leading to the theft of 10 terabytes of data. This dataset included billions of location points, with a sample of 1.4 GB released by the hacker showing 30 million location points. Popular apps like Candy Crush, Tinder, and even VPN services were implicated, raising concerns over privacy and data security. The breach highlights how real-time bidding for ads in these apps can facilitate the unauthorized collection of user data, even from companies that do not win the ad auctions. Consumers are advised to take proactive steps to protect their privacy, including deleting their personal information from data broker websites and adjusting their device settings to prevent tracking.
