NYC Health + Hospitals says hackers stole medical data and fingerprints during breach affecting at least 1.8 million people

NYC Health + Hospitals says hackers were in its network for months via a third-party vendor.

The attackers copied files with personal, medical, billing, and identity information, and may also have taken biometric data.

At least 1.8 million people may be affected, making this one of the largest healthcare data breaches this year.

The incident is especially serious because biometric data like fingerprints cannot be changed if exposed.
