Brinztech Alert: Alleged Employee Database of Fiscalía General de Justicia del Estado de México (FGJEM) is on Sale

Dark Web News Analysis

A threat actor on a known cybercrime forum is advertising the alleged sale of an employee database belonging to the Fiscalía General de Justicia del Estado de México (FGJEM). The dataset reportedly contains personal records for approximately 5,000 employees.

Brinztech Analysis:

• The Target: FGJEM is the Attorney General’s Office for the State of Mexico, one of the most populous and critical regions in the country. A breach here targets the heart of the state’s justice and law enforcement apparatus.
• The Data: The leak is highly granular and administrative. It reportedly includes:
  • Identity Data: Full Names, CURP (Unique Population Registry Code), RFC (Tax ID).
  • Employment Data: Employee IDs, Assigned Units/Departments, Job Positions, Ranks, Codes, and Position Numbers (Plaza).
  • Social Security: Issemym ID (Instituto de Seguridad Social del Estado de México y Municipios).
• The Threat: The seller claims to possess “vulnerability information and full system access,” offering this technical intelligence alongside the data. This suggests the breach is not just a static export but potentially an active backdoor or unpatched exploit (Remote Code Execution or SQL Injection) that allows continued access.

Context: This incident aligns with a severe surge in cyberattacks targeting Mexican government institutions in late 2025. It follows the confirmed ransomware attack on the Fiscalía de Guanajuato (November 2025) and alleged breaches of the Mexico City Auxiliary Police, indicating a coordinated campaign against Mexico’s security infrastructure.

Key Cybersecurity Insights

This alleged data breach presents a critical threat to the physical safety and operational integrity of Mexican law enforcement:

• Physical Safety Risks (Doxing): The most severe risk is the exposure of law enforcement personnel. Linking names and home addresses (often derivable from CURP/RFC data) to specific “Ranks” and “Assigned Units” allows cartels or criminal groups to target specific officers or investigators.
• Systemic Compromise: The seller’s claim of “full system access” implies they have compromised the central administrative network. This could allow attackers to manipulate case files, track ongoing investigations, or delete criminal records.
• High-Fidelity Identity Theft: The combination of CURP, RFC, and Issemym ID is the “holy grail” for bureaucratic identity theft in Mexico. It allows criminals to take out loans or access state benefits in the victim’s name.
• Reputational & Operational Damage: For a justice institution, the inability to protect its own agents erodes public trust. It may force the FGJEM to restructure units or relocate personnel whose covers have been blown.

Mitigation Strategies

In response to this claim, FGJEM and Mexican state authorities must take immediate action:

• Immediate Threat Hunting: Launch a forensic investigation to validate the “full system access” claim. Hunt for web shells, unauthorized VPN accounts, or backdoors in the HR and administrative portals.
• Physical Security Advisories: Issue immediate warnings to all 5,000 affected employees. Staff, especially those in sensitive units, should be advised to increase personal security and monitor for surveillance.
• Mandatory Credential Reset: Force a global password reset for all internal systems. Implement biometric or hardware-based Multi-Factor Authentication (MFA) to prevent the attacker from using stolen credentials to re-enter.
• Regulatory Compliance (LGPDPPSO): The agency must comply with the General Law on the Protection of Personal Data Held by Obligated Subjects. Notification to the transparency institute and affected individuals is likely mandatory.
