Why it matters

The alleged data includes national ID (DNI) and tax ID (CUIT) numbers, full names, dates of birth and sex, plus school name, code and address. According to the analyst note, most people in the dataset are children, and ID numbers issued in childhood are rarely changed, so fraud risk can follow them for years.

What to do

Treat the data as potentially exposed, monitor for confirmations and official statements, and strengthen identity checks and alerts for misuse of minors' DNI and CUIT numbers.
