WASHINGTON -- The agency that allowed hackers linked to China to steal private information about nearly every U.S. government employee -- and detailed personal histories of military and intelligence workers with security clearances -- failed for years to take basic steps to secure its computer networks, officials acknowledged to Congress on Tuesday.
China denies involvement in the cyberattack, and no evidence has been aired publicly proving Chinese involvement although the government says it has "moderate confidence" China was involved.
Lawmakers voiced fears Tuesday that China will seek to gain leverage over Americans with access to secrets by pressuring their overseas relatives, particularly if they happen to be living in China or another authoritarian country.
"China now has a list of Chinese citizens worldwide who are in close contacts with American officials and they can use that for espionage purposes," said Rep. Ron DeSantis, a Florida Republican.
But the fears don't end with China. China's intelligence service could share the information with countries such as North Korea or Pakistan. Also, experts say, many who hack on behalf of the Chinese government are allowed to freelance and sell what they steal.
Democrats and Republicans on the House Oversight and Government Reform Committee spoke in unison to describe their outrage over what they called gross negligence by the Office of Personnel Management. The agency's data was breached last year in two massive cyberattacks only recently revealed.
The criticism came from within, as well. Michael Esser, the agency's assistant inspector general for audit, detailed a yearslong failure by OPM to adhere to reasonable cybersecurity practices, and he said that that for a long time, the people running the agency's information technology had no expertise.
Last year, he said, an inspector general's audit recommended that the agency shut down some of its networks because they were so vulnerable. The director, Katherine Archuleta, declined, saying it would interfere with the agency's mission.
The hackers were already inside her networks, she later acknowledged.
"You failed utterly and totally," said committee Chairman Jason Chaffetz, a Republican. "They recommended it was so bad that you shut it down and you didn't."
Archuleta, stumbling occasionally under withering questions from lawmakers, sought to defend her tenure and portray the agency's problems as decades in the making as its equipment aged. She appeared to cast blame on her recent predecessors, one of whom, John Berry, is the U.S. ambassador to Australia.
Offered chances to apologize and resign, she declined to do either.
Chaffetz said the two breaches "may be the most devastating cyberattack in our nation's history," and said OPM's security policy was akin to leaving its doors and windows unlocked and expecting nothing to be stolen.
"I am as distressed as you are about how long these systems have gone neglected," Archuleta said, adding at another point, "The whole of government is responsible and it will take all of us to solve the issue."
Archuleta and the other witnesses offered few new details about the breaches in the public hearing, deferring most questions about methods and damage to a later, classified session. But Donna Seymour, the agency's chief information officer, confirmed that personnel information on 4.2 million current and former federal employees had been stolen, not just accessed.
The number of security clearance holders whose data has been taken is not yet known, she said. But the records go back to 1985 and include contractors as well as federal employees. Some government officials estimate the number could be up to 14 million.
And because their security clearance applications contain personal information about friends and family, those people's data is vulnerable as well.
