Brinztech Alert: The Alleged Database of E-Serkom is on Sale

Dark Web News Analysis

The dark web news describes the alleged sale of a significant database originating from E-Serkom (e-serkom-ng.co.id), an Indonesian university certification system, on a hacker forum. The database is a massive 7GB SQL dump containing over 100,000 records of Indonesian university accounts. The leaked data is extensive, including bcrypt password hashes, student, alumni, and citizen emails, limited phone numbers, and specific account data from the University of Muhammadiyah Yogyakarta (UMY) and other institutions. The data is reportedly structured and verified, increasing its utility for malicious actors.

Key Cybersecurity Insights

The breach of an educational certification platform exposes the academic sector to specific “Educational OSINT” risks:

• High-Value Target: The database contains sensitive information related to students, alumni, and staff. This demographic is often targeted for phishing campaigns disguised as scholarship offers, job opportunities, or academic alerts.
• Password Reuse Risk: The presence of bcrypt password hashes suggests a high potential for credential stuffing. While bcrypt is strong, students often reuse passwords across social media and university portals. Attackers will likely test these credentials against other Indonesian digital services.
• Structured Data & OSINT: The structured and verified nature of the SQL dump makes it highly valuable for “Educational Open Source Intelligence” (OSINT). Attackers can map the internal hierarchy of universities like UMY or track the career progression of alumni for targeted fraud.
• Specific University Focus: The explicit mention of UMY indicates a targeted focus. Attackers may launch tailored attacks against this specific institution, leveraging internal terminology found in the database to gain trust.

Mitigation Strategies

To protect the academic community and digital infrastructure, the following strategies are recommended:

• Password Reset Enforcement: Mandate immediate password resets for all users, specifically targeting those affiliated with UMY and other affected universities. Advise students and staff to never reuse their academic passwords on external sites.
• Multi-Factor Authentication (MFA): Enforce Multi-Factor Authentication (MFA) on all critical university accounts (portals, email, LMS). MFA prevents unauthorized access even if the bcrypt hashes are cracked or recycled.
• Enhanced Monitoring: Implement enhanced monitoring for suspicious login attempts, especially those originating from unusual geographic locations. Prioritize alerting systems to flag potential credential stuffing attacks against the university’s Single Sign-On (SSO) portals.
• Phishing Awareness Training: Conduct targeted phishing awareness training for students and alumni. Educate them about the risks of credential harvesting emails that mimic official E-Serkom or university certification notices.
