CVS Health recently leaked approximately one billion user records that include email addresses, user IDs, and metadata. The information was discovered in a non-password protected database.
CVS Health acted fast and professionally to secure the data and a member of their Information Security Team contacted me the following day and confirmed my findings and that the data was indeed theirs. I was informed that this was a contractor or vendor who managed this dataset on behalf of CVS Health, but it was confidential as to who the vendor was.
