“We don’t believe the criminal had access to success factors or any payroll data, but they did gain access to an Excel spreadsheet with information about your device. On Wednesday, November 9, the criminal posted this information on the dark web.

“We are aware of the distress this may cause you and we apologize for this happening.”

The email confirmed that the file included information such as employees’ full names, mobile phone numbers and device information, and warned that the data could be used “to increase spam such as spearfishing and social engineering.”

The email concluded by thanking the workers for their “understanding” as the company “continues to respond to this cybercrime.”

A Medibank spokesperson confirmed that hundreds of former and current employees have been arrested in the breach.

“The files released by the criminal include an Excel spreadsheet of approximately 900 current and former employees — including their name, email address, cell phone number, and device information including the asset number and phone name (serial number and IMEI number),” the spokesperson said in a statement sent to news. .com.au.

“While security experts have told us the security risks are low, the information can be used to increase spam like spearfishing.

The hacker will not be able to use the information to access people’s phone data or hack their phones remotely. We have also taken steps through our telecom provider to prohibit the porting of phone numbers to Medibank devices.

“We have offered our employees and former employees the option to change their mobile phone number at no cost to them.

“We also have a specialist psychiatrist available on request.

“For employees who are clients, they can access the same support as any other Medibank and ahm client.”

“There are understandably distressing victims of domestic violence in connection with their address details being made public. We are seeing widespread cases,” he said.

“Some individuals literally live in fear for their lives if their addresses are made public, and others live in fear of public ridicule, losing their jobs, and severing relationships if their sensitive medical information is made public.

“Others are at risk of extortion if their HIV status or other health information is made public. Some Medibank and ahm clients will be police or security officers who are at significant personal risk if their personal data and those of their close family members are made public.”
