Brinztech Alert: The Alleged Database of Ayuttech.ac.th is Leaked

Dark Web News Analysis

The dark web news reports a significant data breach involving Ayutthaya Technical College (ayuttech.ac.th), a prominent vocational institution in Thailand. A threat actor on a hacker forum has released a database dump, approximately 110MB in size, allegedly in MySQL format.

The leak is particularly damaging due to the nature of the exposed data. It contains sensitive Personally Identifiable Information (PII) including Full Names, Usernames, Email Addresses, Phone Numbers, Dates of Birth, Physical Addresses, and most critically, Plaintext Passwords. The fact that passwords were stored without encryption (hashing) indicates a fundamental failure in the college’s data security posture.

Key Cybersecurity Insights

Breaches of educational institutions, especially when involving unencrypted credentials, have long-term consequences for students:

• The “Plaintext” Negligence: Storing passwords in plain text is an obsolete and dangerous practice. It gives attackers immediate, zero-effort access to student and faculty portals. This allows them to view grades, access financial aid documents, or hijack official email accounts to send spam.
• Credential Reuse Cascade: Students often use the same password for their college portal as they do for their social media, gaming, and email accounts. This leak likely compromises the digital identities of thousands of students across the entire internet, not just within the college network.
• Identity Theft Risk: With Dates of Birth, Full Names, and Addresses exposed, students are at risk of identity theft. In Thailand, this data could potentially be used to register fraudulent SIM cards or open digital wallet accounts in the victim’s name.
• SQL Dump Usability: The data was released as a structured MySQL dump. This means attackers can easily import it into their own local servers to query, filter, and sort the victims (e.g., finding all students who live in a specific district) for targeted harassment or scams.

Mitigation Strategies

To protect the student body and secure the college’s infrastructure, the following strategies are recommended:

• Immediate Password Invalidation: The college IT department must force a password reset for every single user account immediately. The new system must store passwords using strong hashing algorithms (e.g., bcrypt or Argon2) rather than plain text.
• Student Advisory: Issue an urgent warning to students: “If you used your college password on any other website (Facebook, Gmail, etc.), change it there immediately.”
• MFA Deployment: Enable Multi-Factor Authentication (MFA) for the student portal. This is the only way to protect accounts if passwords continue to be compromised in the future.
• Vulnerability Patching: Since the attacker obtained a full SQL dump, it is highly likely the website suffered from an SQL Injection vulnerability. The website code must be audited and patched to prevent the attacker from simply downloading the new database next week.
