Fox News correspondent Catherine Herridge reported Thursday that members of the intelligence community are worried about the lack of response to the Office of Personnel Management (OPM) hack from the Obama administration.
The Obama administration has yet to confirm that the Chinese government was responsible for the hack.
"Unlike Sony, where the White House publicly identified North Korea, for OPM the President’s team including counterterrorism adviser Lisa Monaco have made it clear they will not call out China because it might reveal sources and methods," Herridge said.
Sen. Ben Sasse (R., Neb.) said the United States' lack of response would embolden others to attack.
"According to the Defense Department, attribution is the key element of deterrence," Sasse said. "If you don’t admit it’s a big deal and who did it, you embolden lots more attackers."
Director of National Intelligence James Clapper said the next wave of cyber attacks would include data manipulation and deletion.
"The next wave will be data deletions and manipulation that will also be damaging, but as this progresses and people get, they will push the envelope and whether nation states are hacked or individuals, we will so more and more aggressiveness."
Herridge said that the information of more than 22 million people was compromised in the OPM data breach.
