A few weeks after a catastrophic data breach at its Sydney-based company Optus, Singapore Telecommunications Ltd. has reported that its Australian unit Dialog was the target of a cyberattack that may have impacted 1,000 current and former workers as well as fewer than 20 customers.

Singtel said on Monday that the assault on Dialog, an information technology services consulting business located in Australia, had been discovered for the first time on September 10.

At 03:15 GMT, the share price of Singtel had dropped by 1.6 percent.

A breach that occurred late last month at Optus, Australia’s second-largest mobile operator, exposed the personal information of up to 10 million customers. As a result, consumer privacy regulations had to be rewritten in order to make it easier for telecommunications companies and banks to share specific customer information.

The telecommunications company located in Singapore reassured customers that Dialog’s systems were entirely separate from those of Optus and the information technology subsidiary NCS, and that there was no evidence to suggest that data breaches at Dialog and Optus were connected to one another in any way.

The previous week, Dialog came to the realization that “a very tiny sample” of its data, including some personal information pertaining to employee, had been made available on the dark web.

In April, Singtel paid 325 million Australian dollars (about 206.57 million USD) to buy Dialog.
