76GB of Government Data Leaked from Mexico’s CONAMER Servers

Data Breach Summary

A major data leak has exposed sensitive information from Mexico’s Comisión Nacional de Mejora Regulatoria (CONAMER). A user identified as charlotte shared the compromised data on the dark web forum darkforums.st, revealing an extensive breach involving both server files and internal databases.

The leaked content includes 76GB of server files and 40GB of database records related to CONAMER’s digital infrastructure. The data contains detailed personal and institutional information, including names, job titles, emails, phone numbers, physical addresses, server logs, and official documents.

This exposure affects key government portals such as:

  • https://catalogonacional.gob.mx
  • https://conamer.gob.mx/cnmr
  • https://conamer.gob.mx/cuestionarios/
  • https://conamer.gob.mx/transparencia/

The files were compressed to approximately 44.4GB and contain over 329,000 documents, along with 2,912 database entries.

Where and How?

The breach was found circulating on the dark web, specifically on the darkforums.st platform. The exposed materials include .tsv formatted databases and sensitive server-side files such as configuration documents, .PDFs, and .config files (e.g. web.config), some of which contain .NET and Entity Framework settings used in ASP.NET environments.

Company Data Breach History

No prior incidents involving CONAMER have been publicly reported. This appears to be the first known breach tied directly to conamer.gob.mx. However, it aligns with a broader pattern of increasing attacks on Mexican government institutions:

  • RansomHub targeted multiple federal government websites in 2024, claiming large-scale data theft (CyberNews)
  • A separate breach in 2024 exposed 12 million citizen records from empleo.gob.mx (Mexico Business News)
  • Experts warn that 28% of Mexican organizations have experienced confidential data leaks, with the public sector being especially vulnerable (Mexico Business News)

This breach highlights serious weaknesses in the handling of personal and institutional data by public digital systems.

Further Action

It is crucial that CONAMER conducts a full forensic investigation, informs potentially affected individuals, and reinforces its digital security protocols. Proactive communication and transparency are key to regaining public trust and preventing future exposures.

Recommendations for Personal Data Protection

To protect their information, individuals listed in the breach should:

  • Immediately change passwords for any associated accounts.
  • Enable two-factor authentication on all email and government platforms.
  • Avoid reusing passwords across different services.
  • Be cautious of phishing emails or calls that request sensitive information.
  • Monitor credit reports and online activity for unusual behavior.
