Argentina Probes 1-Terabyte Data Dump Linked to Work Management as ARCA Denies Breach

Authorities question the provenance of the trove, pointing to a private broker tied to a shuttered firm.

Overview

  • The archive, first flagged by Daily Dark Web and circulating on forums since November, is reported to contain roughly 1 terabyte of Argentine personal data.
  • Listings describe more than 60 million ARCA records, about 75 million vehicle entries from DNRPA, some 176 million ANSES labor records, and over 100 million mobile-line records, with updates through October–November 2025.
  • The files are attributed to Work Management, described as the successor to SudamericaData, which was closed by court order in 2023 during an illegal intelligence probe.
  • ARCA issued a statement saying its systems were not breached, and government sources told reporters state platforms show no incidents, suggesting the data stem from irregularly compiled private repositories.
  • Judicial and oversight bodies are examining the publications to determine whether to open a new case, as security specialists warn that combined datasets and exposed source code heighten risks of identity theft and targeted fraud.
