The volume of stolen data per victim ranged from one gigabyte to several terabytes. Largan Precision was among the more than forty organizations named on the group’s leak site.

The affected organizations, including Largan Precision, stated they were aware of the claims and were investigating. None of the affected organizations confirmed a significant breach at the time of reporting.
