Singtel has completed initial investigations into a recent breach on a third-party file sharing system and has begun reaching out to affected stakeholders.
Based on investigations and analysis conducted with the help of cyber security experts, the company has established which files on the Accellion FTA system were accessed illegally during the breach and which stakeholders have been impacted.
The data taken includes consumer information containing varying combinations of personally identifiable information. 23 enterprises have also been impacted. These include suppliers, partners and corporate customers.
A large part of the leaked data includes Singtel’s internal information that is non-sensitive such as data logs, test data, reports and emails. Singtel has begun notifying all affected individuals and enterprises to help them and their staff manage the possible risks involved and take appropriate follow-up action.
“While this data theft was committed by unknown parties, I’m very sorry this has happened to our customers and apologise unreservedly to everyone impacted. Data privacy is paramount, we have disappointed our stakeholders and not met the standards we have set for ourselves,” said Singtel’s Group CEO Yuen Kuan Moon.
“Given the complexity and sensitivity of our investigations, we are being as transparent as possible and providing information that is accurate to the best of our knowledge. We are doing our level best to keep our customers supported in mitigating the potential risks.”
Yuen added, “I’d like to thank our customers and partners for their patience and understanding as we continue our cyber and criminal investigations to understand the full extent of this breach. I want to emphasise that our core operations and functions remain unaffected and sound and this incident involves a standalone system provided by a third-party vendor.
“Information security remains our highest priority and you have my commitment that we are conducting a thorough review of our systems and processes to strengthen them.”
