What Happened?

IMDataCenter notified Apex on . After forensic investigators confirmed the intrusion and identified the files involved, Apex concluded on that personal information from class-action and PAGA participants had indeed been compromised.
What Data Was Compromised?
The investigation determined that the following categories of personally identifiable information (PII) were exposed:
