A hacker has breached the Argentinian government’s IT network and stolen ID card details for the country’s entire population, data that is now being sold in private circles.

The hack, which took place last month, targeted RENAPER, which stands for Registro Nacional de las Personas, translated as National Registry of Persons.

The agency is a crucial cog inside the Argentinian Interior Ministry, where it is tasked with issuing national ID cards to all citizens, data that it also stores in digital format as a database accessible to other government agencies, acting as a backbone for most government queries for citizen’s personal information.
