Brinztech Alert: Student Database of Indonesian School SMP Darussalam Kademangan Leaked

Dark Web News Analysis: SMP Darussalam Kademangan School Database Leaked

A database allegedly belonging to SMP Darussalam Kademangan, an Indonesian junior high school, has been leaked on a hacker forum. The breach appears to be comprehensive, exposing sensitive student records, user credentials, and the technical blueprint of the school’s database. The data, which seems to originate from the school’s website (esdasa.sch.id), is a critical security event that puts the school’s vulnerable community of students and staff at risk. The compromised information reportedly includes:

• Student Information (tb_siswa): Student graduation data, full names, national student identification numbers (NISN), class information, and exam scores.
• User Credentials (tb_user): Usernames, email addresses, and passwords, which appear to be weakly hashed with the obsolete MD5 algorithm.
• Technical Data: The full database schema, table structures, and PHP code snippets.

Key Cybersecurity Insights

A data breach impacting a junior high school is particularly severe due to the involvement of minors’ data and is often the result of fundamental security flaws.

• A Critical Breach Targeting the Data of Minors: The exposure of detailed personal and academic information of junior high school students is a severe privacy violation. This data can be used by malicious actors for a wide range of harmful activities, including long-term identity theft that can affect the children for their entire lives, the creation of fraudulent academic records, and launching targeted scams against their parents.
• Leaked Code and Schema Suggest a Classic SQL Injection Flaw: The presence of PHP code snippets and the database structure is a textbook sign of a successful SQL injection (SQLi) attack. This indicates a fundamental and common security flaw in the school’s website, which allowed attackers to bypass security and directly extract sensitive information from the database.
• Compromised Credentials Pose a Wider Threat: The leak of usernames and passwords, especially if weakly hashed, presents a significant risk. These credentials will be cracked and tested in “credential stuffing” attacks against other platforms popular with young people, such as gaming and social media sites, where password reuse is extremely common.

Critical Mitigation Strategies

The school administration must act with extreme urgency to contain this breach and protect its students, while parents and staff must be on high alert.

• For SMP Darussalam Kademangan: Immediately Launch a Full Investigation and Patch: The school’s administration must immediately launch a full investigation to confirm the breach. A top priority is to conduct a vulnerability assessment of the esdasa.sch.id website to find and immediately patch the SQL injection vulnerability.
• For the School: Mandate Universal Password Resets and Notify Community: A mandatory password reset for all student and staff accounts is a critical immediate step. This must be followed by a clear and transparent notification to all students and their parents/guardians about the breach and the specific risks they now face. The school should also upgrade its password storage to a modern, salted hashing algorithm.
• For Parents, Students, and Staff: Be on Maximum Alert for Phishing and Fraud: The entire school community must be warned about this breach. They should be on high alert for phishing scams that may use their real names or academic information to appear legitimate. It is also crucial for every user to immediately change any password that they may have reused on other online platforms.
