Brinztech Alert: Data of SD Hati Kudus Rajawali Makassar are Leaked

Dark Web News Analysis

A threat actor on a known cybercrime forum is claiming to have leaked a database that they allege was stolen from SD Hati Kudus Rajawali Makassar, an elementary school in Indonesia. According to the post, the compromised data is a 29MB zip file containing sensitive information, with file samples indicating it includes both employee and student data. The actor claims a “hacktivist” motive for the leak, stating a desire to “improve your system security,” a common justification for exposing vulnerabilities.

This claim, if true, represents a critical data breach that places young children and their families at significant risk. A database containing the Personally Identifiable Information (PII) of elementary school students and their parents is a powerful tool for criminals. The exposure of this information can lead to long-term identity theft and enables highly effective and cruel social engineering scams that target families.

Key Cybersecurity Insights

This alleged data breach presents a critical threat to the school’s community:

• Severe Risk to Children’s Data: The most significant danger is the exposure of PII belonging to young children. The theft of a minor’s identity is particularly insidious because the resulting fraud can go undetected for over a decade, only surfacing when the child becomes an adult and first applies for credit or employment.
• A Toolkit for Scams Targeting Parents: The data provides criminals with the information needed to craft highly convincing scams. Attackers can impersonate school officials and contact parents, referencing their child’s real name and information to solicit fraudulent payments for fake school fees, field trips, or other expenses.  
• “Hacktivism” Highlights Sector-Wide Vulnerabilities: The actor’s stated motive of exposing weak security, while malicious, points to a real-world problem. Educational institutions, especially smaller schools with limited budgets, are often perceived as “soft targets” by attackers, highlighting the need for improved cybersecurity across the entire education sector.  

Mitigation Strategies

In response to this claim, the school, its community, and the broader education sector should take immediate action:

• Launch an Immediate Investigation by Education Authorities: The school and the local Makassar education authority, with assistance from Indonesian national cybersecurity agencies, must immediately launch a full-scale investigation to verify the claim, assess the scope of the potential breach, and identify the source of the leak.
• Proactive Communication with Parents and Staff: If the breach is confirmed, the school has a critical responsibility to transparently and empathetically notify the parents of all affected students, as well as their own staff. This communication must clearly explain the risks of identity theft and targeted scams.
• Strengthen Security Across all School Systems: This incident must serve as a catalyst for a security review. It is essential for schools to conduct security audits of their student information systems, enforce strong access controls, and provide cybersecurity awareness training to all employees who handle sensitive student data. Implementing Multi-Factor Authentication (MFA) on administrative systems is a critical control.
