Mexico's Migration Database Breach Exposes 1M Sensitive Records

A threat actor is allegedly selling a database containing approximately 1 million records from Mexico's National Migration Institute (INM), exposing highly sensitive immigration and personal data. This breach highlights critical failures in protecting citizen data at government institutions, where inadequate access controls and data protection measures allowed unauthorized access to confidential migration records. The incident demonstrates how government agencies handling sensitive personal information remain attractive targets for cybercriminals seeking to monetize stolen data on underground forums.
