PHI of 23,811 Palmetto Health Patients Exposed in Phishing Attack
Palmetto Health – Now Prisma Health – has experienced a phishing attack that has resulted in several email accounts being accessed by unauthorized individuals.
Emails were sent to Palmetto Health employees which contained a malicious hyperlink. When the link in the emails was clicked, employees were directed to a realistic-looking web page where they were required to enter their email credentials. Doing so disclosed those credentials to the attackers, who used them to gain access to the email accounts.
A third-party computer forensics firm was retained to conduct an investigation into the breach to determine the nature and extent of access and whether any patients’ protected health information had been accessed or obtained.
The forensics firm determined that the first of the email accounts were compromised in November 2018. The review process took some time to complete as emails had to be manually checked to determine whether they contained any protected health information. The review process was completed on February 19, 2019 and revealed the protected health information of 23,811 patients had been exposed.

The exposed information was limited to names and information used by Palmetto Health when providing treatment or consultation. A small percentage of the emails also contained health insurance information, Social Security numbers, and/or financial information.
Palmetto Health believes the aim of the attack was to gain access to payroll information rather than to obtain patient health information. No evidence was uncovered to suggest any patient information was accessed or copied, but data theft could not be ruled out.
Complementary credit monitoring and identity theft protection services have been offered to all patients whose financial information has potentially been accessed.
