Anglicare Sydney says there is no evidence that personal data was stolen despite having identified that a 17-gigabyte data transmission to a remote location took place following the ransomware attack that affected some of its systems on August 31.

The aged care provider has also clarified that the attack only affected Anglicare Sydney and no other Anglicare agency across Australia, refuting a claim in a Sydney newspaper that the breach could have affected the agency's out of home care program for foster children.
