Turkish National Citizenship (MERNIS) 49.6M Database Leak Data Breach

Exposed Data Types
6- National identity numbers
- Names
- Physical addresses
- Dates of birth

About This Breach
Forensic examination of the PostgreSQL dump confirms the compromise of unencrypted personally identifiable information, including 11-digit Turkish National Identification Numbers (TCKN), first and last names, mother's and father's given names, gender, place and date of birth, registration district, and street-level residential addresses.
As one of the most significant national citizenship leaks in modern history, this dataset permanently compromised the baseline authentication credentials of over half the country's population, facilitating synthetic identity creation, targeted fraud, and unauthorized administrative account queries.
