Dialog, a unit of Singapore Telecommunications Ltd (STEL.SI), said on Monday that it faced a cyber attack that could have impacted 1,000 current and former employees and fewer than 20 clients. This news comes weeks after Optus, another Australian company unit, suffered a massive data breach.

Optus, Australia’s second-largest mobile operator, experienced a data breach late last month that compromised the data of up to 10 million customers. This event has overhauled consumer privacy rules to facilitate targeted data sharing between telecommunication firms and banks.

On Monday, Singtel said the Dialog attack, an Australian information technology services consulting firm, began on Sept. 10.

The Singapore-based telecom firm Dialog confirmed that its systems were not connected to Optus or its information technology subsidiary NCS. Additionally, there is no evidence linking the recent data breaches at Dialog and Optus.

Last week, Dialog discovered “a tiny sample” of its data, containing some employee personal information, had been published on the dark web.
