The group claimed possession of more than 200GB of compressed data exfiltrated from Ameriprise's Salesforce environment and internal SharePoint infrastructure, and subsequently published the data after negotiations allegedly failed. The published data contained 500k unique email addresses as well as names, phone numbers, physical addresses and employer information. In their disclosure to state attorneys general, Ameriprise reported 47,876 affected people; the larger email address population represents contacts from Ameriprise's broader operational systems, including internal staff.
