Home delivered groceries business Aussie Farmers Direct has fallen victim to an attack on its systems which has seen the personal details of more than 5000 of its customers posted online.
Attackers today posted the names, phone numbers, email addresses and physical addresses for 5149 of Aussie Farmers Direct's customers.
No credit card or banking details were included in the data dump. It is unclear whether the details are current or from an old backup.
It is understood an attacker contacted Aussie Farmers Direct with a threat to release the data in the days leading up to the hack unless the company handed over a certain amount of money.
The company became aware of the breach late this morning and immediately contacted police and began contacting affected customers.
It also alerted the Office of the Australian Information Commissioner.
"Although we do not store credit card numbers within our systems we have also taken the precaution of contacting our banking partner about the matter," a spokesperson said.
"Aussie Farmers Direct sincerely apologises for any inconvenience this has caused but we are confident that the matter will be resolved quickly.
"We greatly value our customers’ trust and remain committed as ever to providing Australians with a high quality and reliable service. Anyone who has concerns should contact our call centre team on 1300 645 562."
Within just two days of each other, the retailers revealed attackers had managed to infiltrate their systems and steal sensistive customer data.
The federal government has previously pledged to introduce legislation that would make data breach reporting mandatory before the end of the year.
