Clover Health Assessing Impact of Social Engineering Incident
Clover Health Investments has notified the U.S. Securities and Exchange Commission (SEC) about a cybersecurity incident first identified on July 4, 2026. Clover Health Investments is a publicly traded health insurer that provides Medicare Advantage plans, directly contracts with the U.S. government, and manages care for Medicare beneficiaries in 11 states. The company also provides technology and software tools to physicians.
Unusual login activity was identified, and its forensic investigation confirmed that a hacker had accessed three employee email accounts after the employees had been tricked by social engineering into disclosing their credentials. Clover Health activated its incident response plan to contain the incident and believes that unauthorized access has been terminated.
Clover Health said the compromised accounts belonged to non-managerial health plan employees who were responsible for handling member visit scheduling and broker-facing sales work. The accounts did not have permissions to access corporate financial or claims systems, but they could access some personal and protected health information.
The volume of exposed data has yet to be determined, and Clover Health has not publicly confirmed whether sensitive data was exfiltrated from its systems. Clover Health has reported the incident to law enforcement and is working with third-party cybersecurity experts to investigate the incident and review the information that was exposed, viewed, or exfiltrated.
