Brinztech Alert: Alleged Database of IIEG JALISCO Leaked (Plaintext Biometrics Exposed)

Dark Web News Analysis

A threat actor identified as EVORAX has claimed responsibility for a significant data breach targeting the Instituto de Información Estadística y Geográfica (IIEG) de Jalisco. The leak allegedly contains sensitive records in CSV format spanning multiple government sectors, including fiscal, legal, administrative, and educational systems.

Brinztech Analysis:

• The Anomaly (Plaintext Biometrics): The most alarming aspect of this leak is the alleged presence of fingerprint biometrics stored in plaintext. Standard security protocols (like ISO/IEC 19794) mandate that biometrics be stored as encrypted “templates” (mathematical representations), never as raw images or unencrypted data. If true, this represents a catastrophic failure in data architecture.
• The Scope: As the statistical and geographical hub for the state of Jalisco, IIEG centralizes data from various agencies. A breach here implies a “hub-and-spoke” compromise, potentially exposing data related to:
  • Government Employees: Payroll, biometric attendance logs, and internal credentials.
  • Citizens: Fiscal invoices (Facturas), legal filings, and educational records.
• The Threat Actor: EVORAX appears to be a motivated actor targeting Latin American infrastructure. The choice to release this data suggests an intent to damage the institute’s reputation or demonstrate deep access capabilities.

Key Cybersecurity Insights

This alleged breach presents a unique and irreversible threat to the affected individuals:

• The “Immutable Credential” Problem: You can change a password, but you cannot change your fingerprints. If biometric data has been leaked in plaintext/raw format, it can theoretically be used to spoof identity verification systems for life. This compromises everything from smartphone unlocking to biometric banking apps and border control checks.
• Cross-Sector Identity Fraud: The combination of Fiscal Data (RFC/Tax ID) and Legal/Administrative records allows attackers to build “perfect” synthetic identities. They can apply for loans, file fraudulent tax returns, or impersonate government officials with high fidelity.
• Password Hash Vulnerability: While hashes offer some protection, older algorithms (like MD5 or SHA1) are easily cracked. If the salts were also compromised (or if the hashes are weak), the “password” layer of security is effectively negligible.
• Systemic Risk: The leak includes “administrative and financial systems” data. This could expose the internal logic of Jalisco’s government operations, including vendor payments and budget allocations, facilitating future Business Email Compromise (BEC) attacks.

Mitigation Strategies

In response to this critical claim, IIEG Jalisco and affected agencies must take immediate, high-priority action:

• Biometric Risk Advisory (Critical): If the plaintext claim is verified, IIEG must notify affected individuals immediately. These individuals should be advised to disable fingerprint authentication on critical services (banking apps, secure entry points) and revert to strong PINs or hardware keys.
• Compromise Assessment: Immediately analyze the leaked CSVs to determine the exact nature of the “fingerprint” data. Is it raw images (WSQ/JPG) or unencrypted templates? The mitigation strategy differs significantly based on this finding.
• Global Password Reset: Force a password reset for all internal accounts. Ensure new passwords adhere to NIST guidelines and do not rely on previously hashed values.
• Architecture Audit: Conduct a forensic review of why biometric data was stored in an unsecured format. This likely violates Mexican data privacy laws (LFPDPPP) and international standards.
