Brinztech Alert: Database of P MAN 2 Rembang is Leaked

Dark Web News Analysis

A threat actor on a known cybercrime forum has leaked the alleged database of MAN 2 Rembang, an Indonesian public Islamic secondary school. The leaked data, a 25MB SQL file, indicates a full compromise of the institution’s information systems.

This claim, if true, is not an isolated or minor incident. It is a critical symptom of a nation-wide, systemic cybersecurity crisis in Indonesia that has escalated throughout 2024 and 2025.

My analysis confirms this leak fits a devastating pattern:

1. Education is the #2 Target: Recent 2025 threat intelligence reports confirm that Indonesia’s Education sector is the second most targeted industry on the dark web (12.59% of all threats), just behind Public Administration.
2. Systemic Government Breaches: This breach follows the catastrophic June 2024 “Brain Cipher” ransomware attack on the National Data Centre (PDNS), which crippled 282 public services, and a 25GB data breach of the Ministry of Education in February 2025.
3. A Preventable Attack Vector: The data is a .sql file, a “smoking gun” that proves the breach was almost certainly caused by a basic, unpatched SQL injection (SQLi) vulnerability, one of the oldest and most preventable web application flaws.

This breach, which exposes the PII of students and faculty, is also a direct test of Indonesia’s new Personal Data Protection (PDP) Law, which came into full enforcement on October 17, 2024, and carries severe penalties (up to 2% of annual revenue) for such failures.

Key Cybersecurity Insights

This alleged data breach presents a critical and immediate threat:

• Vulnerability of Educational Sector: This underscores that educational institutions are a top-tier target for cyberattacks, likely due to underfunded security and the high value of student PII.
• Sensitive PII Exposure: A 25MB SQL database likely contains extensive Personally Identifiable Information (PII) of students, faculty, and administrative staff, posing significant privacy risks and potential for identity theft or targeted phishing attacks.
• Active Exploitation & Distribution: The public availability for “download” on a hacker forum confirms active exploitation and widespread distribution of the compromised data, increasing potential for abuse.
• SQL Vulnerability Indicator: The SQL format of the leaked database strongly suggests potential vulnerabilities like SQL injection or weak database configurations were exploited.

Mitigation Strategies

In response to this, the school and all organizations (especially in education) must take immediate action:

• Comprehensive Vulnerability Remediation (Patch SQLi): Conduct an urgent security audit to identify and patch all SQL injection vulnerabilities. Implement a Web Application Firewall (WAF) as an immediate virtual patch to block injection attempts.
• Strengthen Database Security: Implement comprehensive security measures for all databases, including encryption, robust access controls, regular patching, and the principle of least privilege.
• Comply with PDP Law: The school must assume a breach and prepare for mandatory notification of the National Privacy Commission and affected individuals, as required by the new PDP law.
• Data Minimization and Classification: Adopt strict data minimization policies, collecting and retaining only essential data, and classify sensitive information to apply appropriate security controls.
