WASHINGTON (Reuters) - U.S. government investigators discovered a separate attack on the federal Office of Personnel Management targeting sensitive information about government employees similar to a hacking incident revealed last week, a senior U.S. official said on Friday.
U.S. investigators also suspect a Chinese link to the attack, a source familiar with the probe said.
The senior U.S. official, who spoke on condition of anonymity, could not confirm a Associated Press report that the information obtained was background data submitted by U.S. intelligence and military personnel for security clearances.
However the official said the cyber intrusion affected “a different set of OPM systems and data” to that disclosed last week. The official could not say when the separate breach occurred.
