Singapore: PDPC accepts voluntary undertaking from Singapore Teachers’ Co-operative Society

In brief

On 30 May 2025, the Singapore Teachers’ Co-operative Society Limited (“Organisation”) executed a voluntary undertaking to improve its compliance with the Personal Data Protection Act 2012 (PDPA). This followed from a data breach that saw the unauthorized access and exfiltration of personal data of the Organisation’s members.


Key facts

The Organisation provides a range of financial products and services to its members. On 11 November 2024, the Organisation notified the Personal Data Protection Commission (PDPC) that a threat actor had exploited vulnerabilities on its website to perform structured query language (SQL) injection attacks to exfiltrate personal data of the Organisation’s members.

The affected personal data included the members’ NRIC number, address, email address, telephone number, nationality, race, gender, marital status, date of birth, age, highest academic qualification, designation, employment status, date of employment/joining the Society, and membership type. The threat actor subsequently used the personal data to send phishing emails to at least 153 members.

Undertaking

The Organisation undertook the following measures:

  1. Audit its internal processes against the PDPC’s Data Protection Essentials and the Cybersecurity Agency of Singapore’s Cyber Essential Mark requirements
  2. Develop an outsourcing management policy
  3. Perform data protection impact assessments
  4. Establish an agreement with the vendor managing the Organisation’s website to address security requirements
  5. Complete the data inventory map documenting the data shared with external parties
  6. Perform due diligence checks on all vendors
  7. Revamp its website
  8. Perform web application penetrating testing on its website and ensure that all identified vulnerabilities are remediated
  9. Review and update its IT and data protection policies
  10. Implement additional technical measures to improve its cyber security

The PDPC will verify whether the Organisation complies with the undertakings and issue a direction to ensure the Organisation’s compliance if necessary.

Key takeaways

This case highlights how vulnerabilities in web applications can be exploited to exfiltrate extensive personal data and how threat actors may further leverage them to conduct phishing attacks. To protect against these risks, organisations should strengthen their data protection and cybersecurity practices, including regularly assessing their web applications and digital infrastructure for potential vulnerabilities. To this end, the undertakings made by the Organisation serve as a good checklist for ensuring compliance with PDPA.
