10. 20/20 Eye Care Network

Number Of Individuals Impacted: 3.25 Million 

20/20 Eye Care Network discovered that data was removed from the S3 buckets hosted in its Amazon Web Services (AWS) environment and all the data in the S3 buckets was then deleted. Hackers might have gained access to the names, addresses, Social Security numbers, member identification numbers, dates of birth, and health insurance information for some or all of 20/20’s health plan members.

A cybersecurity firm investigated the breach for 20/20 and could not tell which files were seen or deleted by the unknown adversary. 20/20 doesn’t think there was any actual misuse of the personal or vision/hearing insurance information of its health plan members, but acknowledged it doesn’t know for sure.

Upon discovering the breach, 20/20 said it moved quickly to investigate and respond, assess the security of its systems, notify potentially affected individuals, and implement additional safeguards and training for its employees. 20/20 said it is also providing access to credit monitoring services at no cost for twelve months to individuals whose personal information was potentially compromised in the breach.
