Singtel-owned Dialog Group suffers data breach

Singtel-owned IT services consulting firm Dialog Group has suffered a potential data breach in Australia, according to Mobile World Live, making it the parent company’s second attack in two months.

Reports suggest the cybe rattack involved access to an undisclosed number of both client and employee information by a third party, some of which were published on the dark web.

The attack comes one month after Singtel’s telco Optus fell victim to a cyber attack in September exposing information of up to nine million customers. According to Singtel, this attack is at a much smaller scale, impacting approximately 1,000 current and former employees, and less than 20 clients.

The consulting firm stated it first detected unauthorised access on its servers in early September, and detected that a “small sample” of the data was available on the dark web a month later (7 October).

The operator stressed that there is no evidence of “any link between this incident and the event experienced by Optus”, adding that Dialog’s systems are kept separate from NCS, Optus and Singtel.

Dialog said it is offering support to those affected and the relevant authorities have been notified of the attack. The consulting firm has also appointed a cybersecurity specialist to conduct a forensic investigation and oversee the dark web.
