Hacks on hospital records are surging. Here's why your medical data is vulnerable.

A growing trend of hackers seeking to disrupt health care or compromise the medical and personal records of tens of millions of people every year.

The number of attacks has surged since 2019 with organized hackers, often located overseas, infiltrating the computer systems of health providers, locking up critical files and disrupting care.

The trend underscores why hospitals and health companies must upgrade systems to repel these attacks.

The HHS Office of Civil Rights had a 69% jump in cases since 2017.

Two-thirds of the cases involved violations of health information privacy and security laws.

The agency's funding has been flat for the past two decades.

Hacking accounts for 80% of the large breaches the agency has received.

The Justice Department did not announce any arrests nor did it reveal the location of the individuals behind the attacks.

In Anthem's 2015 attack, charges are pending against Fujie Wang, 36, of Shenzhen, China, and an unnamed accomplice.

The FBI field office in Indianapolis did not immediately answer questions about attempts to locate Wang.
