In January 2018, The Tribune reported that anonymous sellers were offering access to Aadhaar records through WhatsApp for a small fee. Aadhaar is India’s biometric identity system, used by more than 1.1 billion residents or passport holders at the time, and links demographic information with a unique identification number. Subsequent reporting described insecure access involving government websites and an unprotected API associated with state-owned LPG provider Indane. Reports alleged exposure of names, bank-related information and other personal details, while more than 200 government websites were said to have published Aadhaar-related data inadvertently.
The scale and technical characterization of the incident remain contested. UIDAI unequivocally denied that its central database had been breached, although reported insecure endpoints and websites were taken offline. UIDAI also filed a criminal complaint against The Tribune under Sections 419, 420, 468 and 471 of India’s Penal Code, alleging false reporting. The World Economic Forum’s Global Risks Report described the episode as the world’s largest data breach, but the source does not establish that claim independently. The incident nevertheless exposed the consequences of weak access controls around a near-national biometric identification system.
