Clients of Australian law firm HWL Ebsworth were reportedly not informed of a personal data breach involving the firm for six months, the Guardian reports. Ransomware group ALPHV/BlackCat hacked the law firm in April, stealing 3.6 terabytes of personal data. Sixty-five government agencies were affected, including the Office of the Australian Information Commissioner. HWL Ebsworth claims they delayed telling clients because "a complex manual review was needed to assess what personal information was involved and identify affected persons."
