July 17 (Reuters) - Clover Health Investments said in a regulatory filing on Friday that it ‌detected unusual login activity on some of its ‌information systems on July 4 and later found a hacker had gained access to three employee accounts through social engineering.
• The health insurer said the affected accounts belonged to non-managerial health plan employees who handled member visit ‌scheduling and broker-facing sales ⁠work.
• These accounts could access some personal and protected health information, according to the ⁠company, but not corporate financial or claims systems.
• Clover began an investigation with external cybersecurity experts, took steps to contain the activity and notified law enforcement, it ‌said.
• The investigation is ongoing and the company is still reviewing what information may have been accessed or taken. Clover believes its response curbed and ended the unauthorized access.
