The FBI is collaborating with FireEye to investigate the cyber attack on healthcare provider Anthem Inc. perpetrated by what U.S. government officials believe to be state-sponsored hackers based in China, Bloomberg reported Thursday.
Investigators found technical details and other pieces of evidence that point to a nation-state as the source of the attack, according to the report.
The data breach affected customers that include Michael Daniel, President Barack Obama’s chief adviser on cybersecurity, and employees of Northrop Grumman and Boeing, Bloomberg reports.
Adam Meyers, vice president of intelligence at cybersecurity firm Crowdstrike, told Bloomberg the attack follows the pattern of a hacking group dubbed “Deep Panda.”
The hacking unit has been targeting defense contractors and healthcare providers over the past several months, according to the report.
