Singtel has confirmed that personal details of 129,000 customers, as well as financial information of its former employees, have been compromised in a security breach that involved a third-party file-sharing system. Credit card details belonging to the staff of a corporate client and information tied to 23 enterprises, including suppliers and partners, also have been leaked in the incident.
The announcement on Wednesday came just under a week after the Singapore telco revealed "files were taken" in an attack that affected a file-sharing system, called FTA, which was developed two decades ago by Accellion. Singtel said it had used the software internally and with external stakeholders.
Following its investigations, the telco said compromised personal data belonging to 129,000 customers contained their identification number alongside some other data that included name, date of birth, mobile number, and physical address.
Bank account details of 28 former Singtel staff and credit card details of 45 employees of a corporate client with Singtel mobile lines were also leaked. In addition, "some information" from 23 enterprises including suppliers, partners, and corporate clients were compromised.
Singtel would not offer further details on what exactly this information was, citing security reasons.
The telco did say that a large part of the leaked data compromised internal information that was non-sensitive, such as data logs, test data, reports, and email messages.
It said it has begun notifying affected individuals and enterprises about the breach and was offering help to mitigate potential risks from the breach. This included provisions for a data service provider to provide identity monitoring services, at no additional cost to affected customers, which would be instructed on how to sign up for the service.
