Singtel’s Australian IT services unit Dialog reports cybersecurity incident

Singapore Telecommunications (Singtel) on Monday (Oct 10) announced a cybersecurity incident at Dialog, an Australia-based IT services consulting company acquired in April 2022 by a subsidiary of Singtel-owned NCS.

The group noted that Dialog's systems are completely independent of NCS, Optus and Singtel. There is also no evidence of any link between this incident and the recent Optus security breach which exposed the details of 9.8 million former and current customers.

In a separate statement on Oct 7, Dialog said it became aware of a "very small sample" of its data, including some employee personal information, being published on the Dark Web.

The latest development comes after Dialog detected unauthorised access on its servers on Sep 10. The cybersecurity incident potentially affects fewer than 20 clients and 1,000 current and former Dialog employees, the company said.

The servers were shut down and restored two business days later. Dialog also contracted a cyber security specialist to undertake a deep forensic investigation, which showed no evidence of unauthorised downloading of data at the time.

Dialog also notified relevant authorities and is supporting those impacted to protect against the risk of fraudulent activity, it said.

Singtel's shares closed 0.4 per cent or S$0.01 higher at S$2.53 on Friday.
