Singtel says it is investigating the impact of a cybersecurity breach that may have compromised customer data, after it ascertained on February 9 that “files were taken”. The attack had affected a file-sharing system developed two decades ago by a third-party vendor Accellion, which the Singapore telco had used internally and with external stakeholders. 

Singtel revealed in a statement Thursday it was notified by Accellion that the file-sharing system, called FTA (File Transfer Appliance), had been breached by unidentified hackers. The telco said the tool was deployed as a standalone system and used to share information within the organisation and with external stakeholders. 

All use of the system had been pulled back and relevant authorities, including Singapore’s Cyber Security Agency and local police, were notified. Singtel added that it currently was assessing the nature and impact of the breach, and the extent of data that might have been illegally accessed. 

“Customer information may have been compromised,” the telco said. “Our priority is to work directly with customers and stakeholders whose information may have been compromised to keep them supported and help them manage any risks. We will reach out to them at the earliest opportunity once we identify which files relevant to them were illegally accessed.”
