Cyber attack hits 4 million US federal employees2015-06-05 11:03 by Daniela
Chinese hackers have reportedly compromised the personal information of four million current and former federal employees, from different government agencies. U.S. investigators believe this could be the biggest breach ever of the government's computer networks.
The attack is considered to be linked with earlier thefts of healthcare records from Anthem Inc, the second largest U.S. health insurer, and Premera Blue Cross, a healthcare services provider.
"The FBI is conducting an investigation to identify how and why this occurred," a Department of Homeland Security spokesperson said.
Sen. Susan Collins (R-Maine), a member of the Senate Intelligence Committee, said the hack was "extremely sophisticated," and "that points to a nation state" as the responsible party, likely China.
"We're still evaluating how serious the breach is, but if it does involve the compromising of the personal records of four million Americans, I certainly think that a strong response is warranted," she said.
China authorities have denied to have something in common with the attack and claim that the allegation is irresponsible.
"Cyber attacks conducted across countries are hard to track and therefore the source of attacks is difficult to identify," Zhu Haiquan said.
