What specific systems were compromised in the SLA breach?

Question

Accepted Answer

The Compromised System Was an IBM-Managed Testing Environment, Not Live Operational Systems

A cybersecurity incident involving the Singapore Land Authority (SLA) resulted in the compromise of personal data belonging to approximately 70,000 individuals. The breach occurred due to unauthorised access to a dataset managed within a cloud environment overseen by IBM. This specific environment was designated for vendor development and systems integration testing, and importantly, it is separate from SLA's live operational systems.
IBM Oversees the Compromised Testing Environment

IBM is responsible for managing the testing environment that was accessed without authorisation. This environment is associated with the Singapore Titles Automated Registration System (STARS) and the eLodgment System (ELS). These systems are utilised for the submission of property transfer and caveat documentation.
Dataset Intended for Testing Included Real Information

The dataset at the heart of the incident was initially created in 1998 and updated over time. It was intended to contain only mock and anonymised records for the purposes of vendor development and systems integration testing. However, it was discovered that this dataset inadvertently included real personal information, such as names, NRIC numbers, and past property addresses of around 70,000 individuals.
Live Operational Systems Remain Secure

SLA has explicitly stated that the compromised testing environment is distinct from its live operational systems. Consequently, property ownership and lodgment records within the STARS and ELS remain secure and were not affected by this incident. IBM has taken action to revoke access to the compromised system to prevent any further unauthorised entry.
