Premier Health is investigating how many people were impacted by a data breach this year.
According to a letter sent to patients, Premier Health discovered unusual activity involving certain employee email accounts on June 8, 2020.
Premier Health contracted a cybersecurity forensics vendor who reviewed the content of the compromised mailboxes.
They told News Center 7 that this review could take several months.
The investigation confirmed that certain accounts were subject to unauthorized access by someone not connected with Premier Health, starting on May 5 through June 16.
In the letter, Premier Health said that the investigation could not conclusively rule out that data within the accounts had been accessed.
Premier Health told News Center 7 that they had not determined how many people have been affected by this security incident.
They are offering credit monitoring to those whose Social Security number or driver’s license/state identification number have been identified as impacted. They said at this time, there was no evidence that any information was subject to actual or attempted misuse.
