Mexican Government Database Breach Exposes 152K Records

A threat actor claimed to leak sensitive data from INEGI, Mexico's national statistics institute, including business directories and birth records containing PII. The breach allegedly originated from internal GOB.MX services, suggesting inadequate access controls protecting government databases. Even if portions of business data are publicly available, the combination with sensitive PII records and potential unauthorized access to internal systems represents a significant security failure. This incident highlights the critical need for robust data classification, access restrictions, and monitoring of government databases containing citizen information.
