Brinztech Alert: Sensitive Legal Databases of Poder Judicial de Mendoza on Sale

Dark Web News Analysis

Cybersecurity intelligence from February 19, 2026, has identified a high-stakes listing on a prominent hacker forum advertising a database belonging to the Poder Judicial de la Provincia de Mendoza. A threat actor is offering a structured dataset that appears to have been exfiltrated from the province’s judicial and administrative systems.

The breach is particularly sensitive due to the nature of the information involved—legal records and citizen identifiers within a sovereign judicial framework. The exfiltrated dataset is reportedly structured across three main sections and includes:

• Personally Identifiable Information (PII): Full names, DNI (National ID numbers), home addresses, phone numbers, and birthdates of citizens involved in legal proceedings.
• Legal Service Metadata: Formal requests for legal services, case identifiers, and status updates.
• Privileged Communications: Logs of client-attorney communications and internal administrative notes.
• Financial Metadata: Billing codes and “Centro de Costos” (cost center) identifiers linked to judicial fees and state accounting.

Key Cybersecurity Insights

The sale of a judicial database represents a “Tier 1” threat with profound legal and social implications for the Mendoza region:

• Strategic Social Engineering and Extortion: Armed with specific case numbers and DNI data, attackers can launch hyper-convincing Phishing campaigns. They can impersonate court officials to trick citizens into paying fake “legal fees” or reveal further sensitive information to “prevent an arrest.”
• Compromise of Judicial Integrity: The exposure of internal communications and case metadata could be used to manipulate ongoing litigation or to pressure judicial employees. This undermines public trust in the provincial justice system and its ability to protect the confidentiality of legal proceedings.
• Identity Theft and Financial Fraud: The combination of DNI numbers and physical addresses is sufficient for Identity Cloning. Furthermore, the leaked billing codes provide a roadmap for attackers to execute fraudulent financial transfers or intercept judicial payments.
• Institutional Reconnaissance: By analyzing cost centers and service requests, threat actors can gain insight into the judicial branch’s internal workflows and budgetary allocations, identifying further technical weaknesses for future exploitation.

Mitigation Strategies

To protect your legal privacy and secure your digital identity following this exposure, the following strategies are urgently recommended:

• Immediate Forensic Compromise Assessment: The Poder Judicial de Mendoza must conduct an urgent audit to verify the authenticity of the data. Identify the exfiltration vector—likely a vulnerable web portal or a compromised administrative account—and implement modern encryption standards for all stored legal PII.
• Mandatory Password and Credential Rotation: All judicial staff and registered legal professionals in the province should change their portal passwords immediately. Enforce Multi-Factor Authentication (MFA) across all internal judicial applications.
• Citizen Alert and Transparency: The judicial branch should issue an official advisory to the public. Warn citizens to be skeptical of any unsolicited calls or emails asking for DNI verification or payment for “Legal Services,” even if the sender correctly identifies a current legal case.
• Enhanced Financial Monitoring: Monitor all “Centro de Costos” and judicial billing accounts for anomalous activity. Review and secure the API endpoints used for financial reporting and judicial fee collections.
