Brinztech Alert: The Alleged Database of Cayetano Heredia National Hospital is on Sale

Dark Web News Analysis

The dark web news reports a critical data privacy incident involving Cayetano Heredia National Hospital (Hospital Nacional Cayetano Heredia), a major healthcare institution likely located in Peru. A threat actor identified as @Spirigatito is advertising the sale of a massive database on a hacker forum.

The scale of the alleged breach is alarming, affecting approximately 2.5 million people and totaling 14.8 million records. The dataset is a comprehensive mix of Personally Identifiable Information (PII) and Protected Health Information (PHI). Compromised fields include National IDs, Full Names, Dates of Birth, Residential Addresses, Mobile Phone Numbers, and Email Addresses. Crucially, it also exposes deep medical data: Clinical Record Numbers, Episode & Triage Identifiers, Reasons for Visit, Diagnoses/Clinical Codes, Insurance Details, and internal infrastructure data like Workstation/IP Addresses and Staff Identifiers.

Key Cybersecurity Insights

Breaches of major national hospitals are “Tier 1” human safety threats because they expose the most intimate and permanent details of a person’s life:

• Medical Identity Theft: The combination of National IDs and Insurance Details allows criminals to commit medical identity theft. They can use a victim’s identity to obtain expensive medical services, prescription drugs, or surgery. The victim is then left with the bill and, more dangerously, a corrupted medical history that could lead to wrong treatments in emergencies.
• Extortion & Social Engineering: The exposure of Diagnoses and Reasons for Visit provides attackers with devastating leverage. Patients with sensitive conditions (e.g., infectious diseases, mental health issues) can be targeted for Extortion—threatened with public exposure unless a ransom is paid. Alternatively, phishers can pose as hospital staff calling about “test results” to steal further data.
• Infrastructure Reconnaissance: The leak of Workstation IPs and Staff Identifiers is a major network security risk. It provides a roadmap of the hospital’s internal network, allowing attackers to target specific terminals or impersonate specific staff members to launch ransomware attacks or move laterally across the network.
• Insurance Fraud: With access to Clinical Codes and Policy Numbers, organized crime groups can file thousands of fake insurance claims for procedures that never happened, draining resources from the healthcare system.

Mitigation Strategies

To protect patient safety and hospital operations, the following strategies are recommended:

• Patient Notification: The hospital must urgently notify the 2.5 million affected individuals. Transparency is vital so patients can monitor their medical benefits statements for suspicious activity.
• Infrastructure Hardening: Given the leak of workstation IPs, the IT security team should immediately audit network logs for unauthorized remote access and consider reassigning IP ranges or implementing stricter network segmentation.
• Staff Credential Reset: Force a password reset for all staff members, particularly those whose identifiers were exposed. Implement Multi-Factor Authentication (MFA) on all clinical workstations.
• Medical Record Locking: Advise patients to contact their insurance providers to place a fraud alert on their files, requiring additional verification before any new claims are approved.
