The data of more than 33 million people was compromised during the cyberattack targeting the Viamedis and Almerys cyberattacks, which manage third-party payments for complementary health insurance, the CNIL announced on Wednesday.

“The data concerned are, for the insured and their family, the marital status, the date of birth and the social security number, the name of the health insurer as well as the guarantees of the contract subscribed,” specified in a press release the digital privacy watchdog, adding that banking information, medical data or health reimbursements “would not be affected”.

The CNIL, which will "conduct investigations very quickly" to verify whether the security measures of these operators were in compliance with their obligations, also calls on each of the complementary services using Viamedis and Almerys to inform "individually and directly" all of their policyholders affected by this data breach.
