Massive Data Breach Exposes Sensitive Information of 81.5 Crore Indians

In an alarming revelation, a substantial data breach has exposed the personal and sensitive information of approximately 81.5 crore Indian citizens, raising significant concerns about data security and privacy. A US-based cybersecurity firm called ReSecurity revealed the hack, which revealed a plethora of private information, including names, phone numbers, Aadhaar and passport details, and temporary and permanent residences, among other vital information.

The Breach Details

Resecurity’s detailed report sheds light on the breach, which emerged through a hacker known as ‘pwn0001.’ This individual disclosed the breach on Breach Forums, showcasing the availability of a staggering 815 million records. The stolen data set contains a myriad of personal information, comprising:

  • Name
  • Fathers Name
  • Phone Number
  • Other Number
  • Passport Number
  • Aadhaar Number
  • Age
  • Gender
  • Address
  • District
  • Pincode
  • State

Confirmation and Verification

While the government is yet to officially confirm the data breach, Resecurity’s HUNTER (HUMINT) unit has diligently identified millions of records containing personally identifiable information (PII) belonging to Indian residents. The hacker, pwn0001, substantiated their claims by presenting spreadsheets containing Aadhaar data pieces as evidence. To validate the authenticity of these records, the HUNTER team cross-referenced Aadhaar Card IDs on a government website designated for verifying the validity of Aadhaar details. Shockingly, the data checked out as genuine, raising concerns about the credibility and security of the exposed information.

Additional Leaks and Implications

The breach doesn’t stop at ‘pwn0001’s’ revelation. Another individual, ‘Lucius,’ declared on August 30 about a mammoth data leak amounting to 1.8 terabytes. Named “India internal law enforcement organization,” this extensive leak surpassed ‘pwn0001’s’ records, encompassing even more personal details such as Aadhaar IDs, Voter IDs, driving license records, and records marked with the term “PREPAID.” The latter could potentially signify a connection to companies providing prepaid SIM cards, which often necessitate collecting personal information for customer verification before service activation.

The Gravity of the Breach

The disclosure of such vast personal data on the dark web poses severe implications for the affected individuals and the broader implications on data privacy and security frameworks. The breach not only jeopardizes the personal safety and security of Indian citizens but also points to potential systemic vulnerabilities in data collection, storage, and regulatory safeguards.

Addressing the Crisis

Authorities and organizations must act quickly and work together to minimize the consequences of this breach in light of the alarming situation. Ensuring swift corrective actions, enhancing data security protocols, and fortifying cybersecurity frameworks are critical steps in safeguarding sensitive information and preventing such breaches from occurring in the future.


The magnitude of the data breach affecting 81.5 crore Indians is a stark reminder of the pressing need for robust data protection measures and the urgency to reinforce cybersecurity infrastructure. This incident underscores the critical importance of vigilant data management and comprehensive security practices to avert catastrophic breaches and protect the privacy of individuals in an increasingly interconnected digital landscape.
