Mexican Municipality Suffers Data Breach Exposing 37K Business Licenses

The Municipality of Benito Juárez experienced a significant data breach that exposed nearly 37,000 business licensing records to threat actors. This incident highlights critical failures in data protection and access control measures for sensitive government records. Business licensing data often contains personally identifiable information, financial details, and proprietary business information that can be exploited for identity theft, fraud, or competitive intelligence. The public distribution of this data by cybercriminals demonstrates the cascading impact when government systems lack proper security controls.
