The Dialog Group, an Australia-based IT services consulting company, which was acquired by Singapore Telecommunications (Singtel) subsidiary NCS, has been hit by a cybersecurity attack, where company data was leaked.
The leak has potentially affected fewer than 20 of Dialog’s customers and 1,000 current Dialog employees as well as former employees.
According to Singtel, there is no evidence that this attack is linked to the other attack experienced by Optus.
“On Saturday 10 Sept, we detected unauthorised access on our servers, which were then shut down as a preventative measure. Within two business days, our servers were restored and fully operational,” reads the statement released by Dialog on Oct 10.
“We contracted a leading cyber security specialist to work with our IT team to undertake a deep forensic investigation and continuous monitoring of the Dark Web. Our ongoing investigations showed no evidence of unauthorised downloading of data,” it adds.
“On Friday Oct 7 we became aware that a very small sample of Dialog’s data, including some employee personal information, was published on the Dark Web,” it continues.
