2026 Serasa Experian (Brazil) — historic 223M+ dossier recirculated on forums (April attention wave)
Data compromised
CPF-linked credit and PII fields per Brazilian leak analyses
Technical writeup
In April 2026, cyber-intelligence dashboards revived attention on a massive Brazilian credit-bureau–style dataset frequently associated in press with Serasa Experian branding, citing figures on the order of 223 million people and multi-terabyte archives, often described as repackaging or re-sharing 2022-era source material rather than a freshly confirmed 2026 perimeter hack. Cybernews and NGO summaries emphasized verification challenges, duplicate data, and political fallout. Treat as a market recirculation / forum visibility event unless Serasa issues a new incident-specific confirmation.
Root cause
Criminal resale or recompilation of historic bureau-scale tables
