Singapore Telecommunications said its unit Dialog faced a cyber attack that potentially affected 1,000 current and former employees and fewer than 20 clients.
Optus, Singtel’s another business unit in Australia, faced cyber attack recently.
The data breach at Optus, Australia’s second-largest mobile operator, late last month compromised data of up to 10 million customers, triggering an overhaul of consumer privacy rules to facilitate targeted data sharing between telecommunication firms and banks.
Singtel, Singapore-based telecom operator with presence strong presence in Asia, said on Monday the attack on Dialog, an Australia-based information technology services consulting firm, was first detected on Sept. 10, Reuters news report said.
The Singapore-based telecom firm assured that Dialog’s systems were independent of Optus and information technology unit NCS, and that there was no evidence of any link between the incidents of data breaches at Dialog and Optus.
Last week, Dialog realised a very small sample of its data, including employee personal information, had been published on the dark web. Singtel had acquired Dialog in April for A$325 million ($206.57 million).
