The hacking occurred in March and the perpetrators appeared to be targeting the files of people who had applied for top-security clearances, the Times said, quoting senior US officials.
The report came as US Secretary of State John Kerry was in Beijing for two days of high-level talks on thorny issues including hacking.

The paper quoted one senior US official as saying the attack was traced to China although it was not clear if the hackers belonged to the government.
