Brinztech Alert: Database of a Thai Company (16M Records) is on Sale

Dark Web News Analysis

A threat actor on a known cybercrime forum is advertising the alleged sale of a database belonging to a Thai company. The dataset purportedly contains 16 million user records.

This claim, if true, represents a critical, nation-scale data breach affecting a massive portion of the Thai population (nearly 25%).

Target Analysis: The specific data fields listed—student_code, height, weight, gender, and age—are the “smoking gun.”

• Not a Standard Corporate Leak: A typical e-commerce or corporate breach does not store “student codes” or “height/weight.”
• Likely Source: This specific combination strongly suggests the victim is a National Student Health/Growth Tracking Platform, a major EdTech provider used by schools nationwide, or a Government Education Agency. The “16 million” figure likely covers nearly the entire student population of Thailand, plus historical records (alumni).

This alleged breach is not an isolated incident. It is the latest in a catastrophic 2024-2025 data breach crisis in Thailand. It follows the “9Near” hack (55M records) and the 23M record breach of Vietnam Airlines (which impacted Thai citizens). It creates a perfect storm for identity theft in a country where the National ID Card (13 digits) is the key to all digital services.

Key Cybersecurity Insights

This alleged data breach presents a critical and immediate threat:

• Vulnerable Sector Targeting (Education/Health): The inclusion of ‘student_code’ and health metrics (height, weight) suggests the target is an educational institution or a company handling a large volume of student health data. This makes a vulnerable demographic (minors) susceptible to exploitation.
• Extensive PII Exposure: The breach involves 16 million records containing highly sensitive PII, including Thai ID card numbers, full addresses, and contact information. This is a complete identity theft kit.
• Comprehensive Data for Advanced Attacks: The breadth of data points (demographics, precise location, ID details) can be leveraged for highly personalized phishing, social engineering (e.g., “Your child’s health report is ready”), and potentially even physical threats against individuals.
• Regulatory Crisis (PDPA): This breach is a direct challenge to Thailand’s Personal Data Protection Act (PDPA). With the PDPC recently issuing fines of 7 million THB for smaller breaches, the penalty for a leak of this magnitude involving minors’ data would be historic.

Mitigation Strategies

In response to this systemic threat, all educational and public sector organizations in Thailand must take immediate action:

• Immediate Incident Response and Verification: Conduct an urgent investigation to verify the authenticity of the breach. If you manage student data with “height/weight” fields, assume you are the target.
• Data Breach Notification (PDPA Compliance): If confirmed, the organization must notify the Personal Data Protection Committee (PDPC) within 72 hours and the 16 million affected individuals, as required by law.
• Review Third-Party and Vendor Security: Assess all third-party vendors (especially EdTech and health tracking apps) with access to student data. This breach likely originated from a supply chain partner with aggregated access to multiple schools.
• Strengthen Access Management: Implement robust multi-factor authentication (MFA) across all critical systems and encrypt sensitive fields (especially National IDs and Student Codes) at rest.
