Fujie Wang, 32, a Chinese national, and another person identified as "John Doe," alleged to be part of an "extremely sophisticated hacking group" based in China, were charged by federal prosecutors in connection with the 2014 data breach that affected nearly 80 million customers of Anthem Inc., one of the nation's largest health insurance companies. 

The indictment charges Wang and Doe of targeting Anthem and committing "one of the worst data breaches in history,” according to a news release from the Department of Justice.“

The defendants are accused of installing malware and tools on the compromised computer systems and identifying ‘data of interest’ on the computers, which included personal information, according to the indictment. 

They allegedly stole data from approximately 78.8 million people from Anthem's computer network, including names, health identification numbers, dates of birth, Social Security numbers, addresses, telephone numbers, email addresses, employment information and income data, the indictment states.”
