The U.S. plans to "keep up the pressure" on China as it gauges that nation's response to this week's indictment of five Chinese military officials for allegedly hacking into American corporate computers, a senior administration official said Friday.

If China doesn't begin to acknowledge and curb its corporate cyberespionage, the U.S. plans to start selecting from a range of retaliatory options, other officials said.

They include releasing additional evidence about how the hackers allegedly conducted their operations, and imposing visa, business and financial restrictions on those indicted or people or organizations associated with them.

Beyond that, some officials are advocating more stealthy moves. These could include the government working with a U.S. company that has been breached to feed hackers bad data, said one person familiar with the discussions.

U.S. Attorney General Eric Holder announced the charges Monday, alleging the five men hacked into five U.S. companies, including Alcoa Inc. and U.S. Steel Corp., as well as the United Steelworkers union, to take sensitive information. U.S. officials said they expected the Chinese would strike back.

But so far, China's response has been fairly restrained: denying the accusations, canceling the nation's participation in cybersecurity talks and signaling that U.S. technology companies may face greater scrutiny in trying to do business in China.

A senior administration official said the Chinese response is as expected, and the U.S. will tie any retaliation to Beijing's longer-term reaction.

"It has to be calibrated some to what the Chinese government chooses to do," the senior administration official said. "This is a long-term process."

U.S. officials expect it will take a few more weeks to discern the true Chinese response.

"If the Chinese don't re-engage, they [U.S. officials] have more things in their bag of tricks," said James Lewis, a cybersecurity specialist at the Center for Strategic and International Studies who frequently consults with the Obama administration.

Chinese officials in Washington didn't immediately respond to a request for comment.

The indictment in federal court in Pittsburgh is part of a much broader strategy to counter a growing cyber assault against the U.S. government and companies, which intelligence officials have said tops their list of national security threats.

The indictment seems to be in direct response to a challenge Chinese officials issued more than a year ago, when U.S. officials launched a public shaming campaign to try to press China to stop hacking U.S. companies. Chinese officials called on the Americans to put forward the kind of evidence that would hold up in court.

Monday's indictment, in effect, is aimed at providing a foundation on which the U.S. government could build an array of punishments. It sets out evidence in detail--naming alleged actors and affected U.S. companies and organizations--that could be used to support additional penalties.

"Criminal charges can justify economic sanctions from our colleagues in the Treasury Department, sanctions that prevent criminals from engaging in financial transactions with U.S. entities and deny access to the U.S. financial system," said John Carlin, the head of the Justice Department's national security division, in a speech Wednesday at the Brookings Institution think tank. "They can facilitate diplomacy by the State Department."

On the prosecutorial side, follow-on steps may include releasing more evidence about the hacking cases, or filing new charges in other hacking cases in which investigators have collected a critical mass of evidence, officials say.

Officials were mum on the nature of the additional evidence. But a person familiar with U.S. probes into Chinese hacking said investigators often collect video evidence of hackers.

"Some of these actors are not real good about turning off the Skype camera on their machines while they are working," this person said.

A more controversial response advocated by some Federal Bureau of Investigation officials is to work with companies under cyber siege to feed bad information to hackers, said a person familiar with the discussions. The goal would be to cast doubt on the quality of the data being stolen, and in addition raise questions about information taken from other companies.

If executed as a counter-spying campaign, advocates of the approach say it would force Chinese officials to spend much time trying to separate bad information from good and lead them to centralize their diffuse operations, which could slow the pace of their cyberspying.

The idea is "getting a lot of traction, both on the commercial and government sides," said the person familiar with the discussions. "The dilemma has always been finding companies willing to cooperate."

Another option government officials are considering is putting individuals or organizations linked to hacking, such as Chinese universities or government contractors, on Department of Commerce lists of "parties of concern." People or entities on the lists are essentially red-flagged by the U.S. government and can't trade with Americans or conduct financial transactions in the U.S. The move also could bar faculty or graduate students at listed universities from fellowships or conferences in the U.S.

In the past, it has been difficult to use the lists in hacking cases, because evidence pointing to specific responsible entities was limited. Monday's cases now provide that kind of evidence.

Government officials are also weighing actions at the Treasury Department, such freezing assets or imposing individual sanctions, according to two people familiar with the discussions.

Those penalties could take a form similar to those levied against Russian business people in the wake of Russia's annexation of Crimea.

Officials in additional are assessing whether and how they might impose visa restrictions to prevent Chinese hackers from attending popular hacker conferences in the U.S., such as the annual Defcon conference in Las Vegas.

Another option under consideration is whether to take action at the World Trade Organization.

Monday's indictment focuses on trade-secret theft, and some U.S. officials believe they can make the case that Chinese hacking represents intellectual-property theft in violation of the WTO's trade-related aspects of intellectual-property rights.

U.S. officials also are looking to allies to both endorse the U.S. cases outlined Monday and take action of their own. Investigations "can lead other governments to take action, even when the United States doesn't end up doing so," Mr. Carlin noted.
