Proxyearth is a new online tool that claims to locate any Indian citizen using just their mobile phone number. Launched in October 2025, it offers detailed personal information, including full names, addresses, email accounts, and even Aadhaar card numbers. The site presents this data on a map and allows users to view extensive API responses that reveal additional personal identifiers. Hackread.com tested the service with a private number and found the information accurate, raising serious privacy concerns about how easily such data can be accessed. The source of Proxyearth's data is unclear, but it likely comes from breaches of telecom companies and government databases. A report from January 2024 highlighted a massive 1.8TB database on the dark web containing the personal information of 750 million Indian mobile users. Although Bharti Airtel denied a breach in 2021, a hacking group claimed to have accessed millions of customer records, including sensitive details. This history suggests that Proxyearth may be exploiting previously leaked data to provide its services. Proxyearth's website downplays its capabilities, presenting itself merely as a mobile number tracking tool. It does not disclose the origins of its data, who runs the site, or whether its operations are legal. The lack of transparency raises significant ethical and regulatory questions. The potential implications extend beyond individual privacy; the tool poses a direct threat to national security. With access to precise geolocation and sensitive personal data, the risk of targeted surveillance or espionage becomes a real concern for various groups, including government officials and journalists.
