Brinztech Alert: Database of Indonesian High School SMA Islam YMI Wonopringgo on Sale

Dark Web News Analysis

A threat actor is advertising a database for sale on a cybercrime forum, claiming it was stolen from SMA Islam YMI Wonopringgo, a high school in Indonesia. The seller states the database is 2GB in size and is being offered for the extremely low price of $50 USD. To prove the data is legitimate, a sample has been provided to potential buyers.

This is a critical security incident that poses a significant threat to a vulnerable population. A school database typically contains a rich set of Personally Identifiable Information (PII) on students, many of whom are minors, as well as their parents and school staff. The extremely low asking price is a strong indicator that the seller’s primary motive is not profit, but to ensure the data is distributed as widely and as quickly as possible to a large number of low-level malicious actors. This exponentially increases the likelihood that the compromised information will be actively used for identity theft, financial fraud, and highly targeted scams.

Key Cybersecurity Insights

This data breach presents several immediate and severe threats:

• High Risk to the PII of Minors and Their Families: School databases contain highly sensitive information, including student names, dates of birth, home addresses, and parent contact details (names, phone numbers, emails). The exposure of this data puts students and their families at a high, long-term risk of identity theft and other forms of fraud.
• Low Price Guarantees Widespread, Malicious Use: An asking price of only $50 makes this data accessible to virtually any opportunistic cybercriminal. Unlike expensive corporate data, which is often purchased by a single sophisticated group, this data will likely be purchased by hundreds of different actors, leading to a massive and uncontrolled proliferation of fraud and phishing campaigns targeting the victims.
• Foundation for Highly Credible Family-Targeted Scams: The most direct and dangerous threat is that criminals will use this data to launch highly convincing scams targeting parents. By using a student’s real name, school name, and other personal details, attackers can craft credible-looking fake emails or text messages regarding urgent tuition payments, school emergencies, or scholarship opportunities, with the goal of tricking parents into sending money or revealing sensitive financial information.

Mitigation Strategies

In response to this significant threat, the school and its community must take immediate action:

• School Must Immediately Launch an Investigation and Secure Systems: The administration of SMA Islam YMI Wonopringgo must assume a breach has occurred and immediately launch an internal investigation, ideally with the help of a professional cybersecurity firm and national authorities like Indonesia’s BSSN. Their top priorities are to confirm the breach, identify and patch the security vulnerability that was exploited, and secure their network to prevent any further data loss.
• Proactive and Transparent Notification to All Parents and Staff: If the breach is confirmed, the school has a critical ethical and legal responsibility to proactively and transparently notify all students, parents, and staff. This communication must clearly state the types of information that were stolen and provide clear, actionable guidance on the specific risks they now face, particularly regarding targeted fraud.
• Parents and Staff Must Be on Maximum Alert for Phishing and Scams: All parents and staff associated with the school must operate under the assumption that their data is compromised. They must be extremely vigilant for any unsolicited or unusual emails, text messages, or phone calls purporting to be from the school. All requests for payment or personal information should be independently verified by calling the school directly using a known, trusted phone number.
