Brinztech Alert: Alleged Database of a Peruvian Company is Leaked (PII & Tax IDs)

Dark Web News Analysis

A threat actor on a known hacker forum is distributing an alleged database belonging to a Peruvian company. The dataset is available via a direct download link, indicating it has been leaked rather than exclusively sold.

Brinztech Analysis:

• The Target: While the specific company remains unnamed in the initial report, the data fields confirm it is a Peruvian entity holding sensitive citizen information.
• The Data: The leaked sample includes comprehensive Personally Identifiable Information (PII):
  • Identity: IDs (DNI), Names, Document Codes.
  • Contact: Email addresses, Phone numbers, Full Addresses.
  • Financial/Tax: NIF (Tax Identification Number / RUC).
• The Threat: The inclusion of “Document Codes” (likely the Dígito de Verificación or specific ID batch numbers) alongside NIF/DNI is critical. In Peru, these specific codes are often required to validate identity for online government services (like Reniec) or banking applications.

This incident adds to the growing list of breaches targeting the Andean region in late 2025, following the high-profile attacks on Interbank and Movistar Peru.

Key Cybersecurity Insights

This alleged data breach presents a critical threat to Peruvian citizens and the local business ecosystem:

• Significant Data Exposure (Identity Theft): The exposed data contains a wide range of PII sufficient for synthetic identity fraud. Criminals can use the NIF and Document Codes to impersonate victims, apply for loans, or register fraudulent SIM cards.
• Regulatory Implications (LPDP): This breach falls under Peru’s Law for the Protection of Personal Data (LPDP). The compromised company faces mandatory reporting requirements to the National Authority for Personal Data Protection (ANPD) and potential fines if negligence is proven.
• Active Exploitation Risk: The availability of the database via a download link (rather than a high-priced auction) significantly increases the risk. “Free” or easily accessible data is rapidly adopted by low-level cybercriminals for mass phishing and smishing campaigns.
• Geographic Specificity: The focus on a Peruvian company suggests a targeted attack or the exploitation of a regional vulnerability (e.g., a specific local ERP or e-commerce platform software common in the region).

Mitigation Strategies

In response to this claim, Peruvian organizations and affected individuals must take immediate action:

• Data Breach Assessment: Organizations operating in Peru must immediately check their own user databases against the leaked samples to determine if they are the source.
• Credential Monitoring: Affected users should assume their passwords are compromised if they reuse them. Implement Multi-Factor Authentication (MFA) on all email and financial accounts immediately.
• Enhanced Fraud Detection: Financial institutions should flag accounts associated with the leaked NIFs for unusual activity, especially changes to contact information or new credit inquiries.
• Incident Response Plan: Activate incident response protocols to identify the entry point (likely an unpatched web vulnerability or compromised vendor) and close the security gap.
