Is Your Phone Being Tracked Through Ads? Data Broker Investigation Reveals Alarming Truth

The Unsettling Revelation of Locate X: How Mobile Ad Data Fuels a Vast People-Tracking Network

Recent investigative reports from 404 Media and Krebs on Security have unveiled a deeply concerning development in the world of data privacy: Locate X, a powerful people-tracking software capable of monitoring individuals’ movements using their mobile advertising identifiers. This revelation highlights the inherent vulnerabilities within the mobile advertising ecosystem and underscores the urgent need for stronger data privacy regulations and transparency in the technology industry.

The investigation, spearheaded by the New Jersey-based Atlas Data Privacy Corp, paints a chilling picture. Atlas, an organization dedicated to helping individuals remove their personal information from data brokers, discovered that Locate X, developed by Babel Street, can pinpoint a person’s precise location by leveraging their mobile advertising identifier (MAID). This unique number, assigned by Google and Apple to each smartphone, is initially used for targeted advertising. But as the investigation revealed, it’s being weaponized for far more invasive purposes.

The mechanics of Locate X are deceptively simple, yet terrifyingly effective. By aggregating data from numerous apps and websites that deliver ads, advertisers build profiles associated with each MAID. These profiles include location data, creating a network of tracked locations. Babel Street then leverages this aggregated data to power Locate X, generating a map displaying the movements of individuals represented as red dots. A screen recording obtained by 404 Media showcased a disturbing example: hundreds of mobile phones clustered over an abortion clinic, demonstrating the potential for misuse. The software then tracked a specific device, following its trajectory from Alabama, to various locations like a Lowe’s and a church, culminating at an abortion clinic in Florida. This clear illustration of the software’s capabilities underlines the potential for serious privacy violations and even physical harm.

The implications of Locate X’s capabilities are far-reaching and deeply unsettling. The technology has the potential to:

• Undermine personal safety and freedom of movement: The ability to track an individual’s movement across state lines presents a grave threat to anyone concerned about surveillance, stalking, or harassment. Its application to monitor individuals visiting sensitive locations like abortion clinics underscores the very real dangers faced by marginalized communities seeking access to healthcare. The potential for misuse by malicious actors is simply too significant to disregard.
• Enable sophisticated surveillance: The technology extends far beyond tracking individuals to specific locations; it allows for the reconstruction of detailed behavioral profiles, revealing personal patterns and habits. This highly sensitive information could be misused for political manipulation, targeted advertising, or even more sinister purposes.
• Exacerbate existing inequalities: The technology disproportionately impacts vulnerable populations, such as those seeking healthcare services or engaging in activism. The monitoring of individuals at abortion clinics highlights the specific risks faced by women seeking reproductive care.

The investigation also revealed concerning aspects of Babel Street’s sales practices. An Atlas investigator, posing as a potential customer interested in purchasing New Jersey home addresses, was presented with Locate X by a Babel Street salesperson. While claiming that the software is only available to government officials or contractors, the salesperson’s response when the investigator indicated potential future government work was telling: "that’s good enough" and "they don’t actually check." This apparent laxity in verifying the identity and legitimacy of clients raises serious concerns about the software’s potential for misuse and the lack of effective oversight by Babel Street.

This incident highlights a crucial gap in existing regulatory frameworks. While many regulations govern the collection and use of personal data, the industry often operates in a gray area, making it difficult to effectively enforce existing rules or develop new ones. The use of MAIDs, originally intended for targeted advertising, to enable precise location tracking brings into sharp focus the potential for data repurposing and the potential for unforeseen negative consequences.

The future of mobile data privacy depends on several key steps:

• Increased transparency about data collection and use: Companies must be more transparent about how they collect, use, and share user data, including details about the potential downstream applications of this data. Consumers must be informed and given meaningful consent options for the collection and use of their location information.
• Development of stronger data protection regulations: Governments worldwide must strengthen data privacy regulations to address the increasing sophistication of data tracking technologies. Laws must adapt to the dynamic landscape of technology, specifically targeting tools like Locate X that exploit loopholes in existing legislation.
• Enhanced scrutiny of data brokers: Data brokers hold vast quantities of personal data, and this data is often used in ways that are opaque and potentially harmful. More rigorous oversight and regulation of the activities of these brokers are essential.
• Empowerment of consumers: Individuals should be better equipped to understand and control their data. This involves providing clear and concise information about data privacy and providing easy-to-use tools that allow individuals to manage their data and opt out of various tracking practices..

The revelations surrounding Locate X constitute a wake-up call. The pervasive nature of data collection through seemingly innocuous means raises profound ethical and societal concerns. The software’s ability to track individuals’ movements with alarming precision highlights the need for immediate and impactful action. Unless there’s a fundamental shift towards greater transparency, stricter regulations, and enhanced consumer control, the potential for misuse of location data, with implications for liberty, safety, and justice, will continue to grow. The investigation into Locate X should serve as a catalyst for a much-needed conversation on how to protect individuals from the increasingly intrusive capabilities of data-driven surveillance technologies.
