The agency responsible for the national disability insurance scheme is scrambling to learn whether sensitive client information related to appeal cases has been caught up in a large cybersecurity hack on the law firm HWL Ebsworth which has represented the agency.
The Russian-linked ALPHV/Blackcat ransomware group said in a post on the dark web in late April that data from the law firm had been hacked. Earlier this month, the group published some of the data it claimed to have stolen – later established to be 3.6TB worth of data, of which 1.1TB has been posted.
