Today, in a world connected by many smartphone apps, sharing your location data is sometimes a prerequisite for convenience. Location-based services are a part of everyday life, from finding the nearest coffee shop to following your fitness routine. But the trust can be exploited: a recent hack has shown how a data broker, Gravy Analytics, has been collecting, storing and potentially selling user location data, placing millions at risk.
The Real-Time Bidding Problem
Today’s most popular apps are all built around the ability to make revenue from ads, meaning that users do not need to pay to enjoy the app. In the past, location data companies would pay app developers to plant code in their apps so you could extract location data. However, in Wired and 404 media, investigative journalist Joseph Cox says the game has changed with the real-time bidding (RTB) rise.
RTB is the simple idea of an auction for ads and using that auction to run ads based on a user’s activity in an app. Apps can share app and sensitive data with advertisers during this process, such as location. And now, the recent hack shows Gravy Analytics, a top location data broker, has been hoarding these massive stacks of data, including smartphone coordinates. Government agencies and private companies do not sit well with unauthorized surveillance.
The Scope of the Breach
Security researcher Krzysztof Franaszek said most of the leaked geolocation data came from IP addresses rather than GPS data. However, the sheer size of the breach is staggering. Over 12,000 apps across various categories were affected, including:
- Dating apps: Tinder, Grindr
- Flight tracking apps: Flightradar24
- Period tracking apps
- VPN services
- Popular games: Subway Surfers, Candy Crush and Temple Run.
The scope of this breach goes beyond platforms; Android and iOS users are affected too.
How It Happened
Gravy Analytics reports that hackers accessed their systems and leaked data samples on an underground cybercrime forum named XSS. They also posted messages on Gravy’s websites briefly describing the breach. Those messages were quickly cleaned away, they highlighted the scope of the exposed data and smeared Gravy Analytics as unethical data pros.
Risks and Implications
“This is a nightmare scenario,” said Zach Edwards, a senior threat analyst at Silent Push. The potential consequences are vast:
- Privacy Violations: Data derived from location could be used for surveillance, stalking and harassment.
- De-anonymization Risks: By mixing data on real-world locations with data on real people, the location data can become the target by itself, allowing people who want to locate a person to identify.
- Loss of Trust: If your users are unaware of Gravy Analytics’ actions, they will have little confidence in app developers’ and platforms’ actions.
App Developers Respond
Gravy Analytics is distancing itself from some app developers. For example, Match Group, which owns Tinder and Grindr, told 404 Media they have no connection to the data broker. However, developers’ knowledge about this data collection was kept in the dark, which is not just a problem for Facebook and the other companies mentioned. It is a testament to the opacity of the digital advertising ecosystem.
What is Next?
Google and Apple have not said much as the fallout from this hack continues. Both have strict guidelines on user data privacy and whatever their response is will be crucial to placating their users and preventing future breaches.
This is a salient incident that users should be cautious about. Keeping an eye on what permissions are being requested, discontinuing location access for non-essential apps, and taking advantage of privacy-focused tools will all affect.
A Call for Accountability
This breach is yet another reminder of weak regulations and a lack of transparency in data collection and sharing. We must address end-user privacy violations, which should be a priority for governments and tech companies.
In today’s age of data as currency, users, developers, and regulators need to demand and protect personal information. In fact, the Gravy Analytics hack is a wake-up call that should not be ignored. If you want to learn more about Sundar Pichai Previews Google’s AI-Powered Vision for 2025, Read on.
