Chinese cyberattacks prompt U.S. to beef up Pentagon security, weigh action against Beijing

WASHINGTON In the wake of two major U.S. newspapers reporting cyberattacks by China-based hackers, the Pentagon now is pushing to expand its cyber-security forces, CBS News correspondent Bob Orr reports.

The U.S. military's so-called Cyber Command will grow five-fold over the next few years, from 900 employees presently to nearly 5,000 civilian and military personnel, Orr reported on "CBS This Morning" Friday.

The Obama administration is also considering more assertive action against Beijing to combat a persistent cyber-espionage campaign it believes Chinese hackers are waging against U.S. companies and government agencies.

As The New York Times and Wall Street Journal reported Thursday that their computer systems had been infiltrated by hackers in China, cybersecurity experts said the U.S. government is eyeing more pointed diplomatic and trade measures.

Two former U.S. officials told The Associated Press the administration is preparing a new National Intelligence Estimate that, when complete, is expected to detail the cyberthreat, particularly from China, as a growing economic problem. Neither of the former officials was authorized to discuss the classified report and spoke only on condition of anonymity.

One of the former officials said the NIE, an assessment prepared by the National Intelligence Council, also will cite more directly a role by the Chinese government in such espionage. The former official said the NIE will underscore the administration's concerns about the threat and will put greater weight on plans for more aggressive action against the Chinese government.

Secretary of State Hillary Rodham Clinton, in an interview with reporters as she wound up her tenure, said the U.S. needs to send a strong message that it will respond to such incidents.

"We have to begin making it clear to the Chinese — they're not the only people hacking us or attempting to hack us — that the United States is going to have to take action to protect not only our government's, but our private sector, from this kind of illegal intrusions. There's a lot that we are working on that will be deployed in the event that we don't get some kind of international effort under way," she said.

"Obviously this can become a very unwelcome and even dangerous tit-for-tat that could be a crescendo of consequences, here at home and around the world, that no one wants to see happen," she said.

Although the administration hasn't yet decided what steps it may take, actions could include threats to cancel certain visas or put major purchases of Chinese goods through national security reviews.

"The U.S. government has started to look seriously at more assertive measures and begun to engage the Chinese on senior levels," said James Lewis, a cybersecurity expert at the Center for Strategic and International Studies. "They realize that this is a major problem in the bilateral relationship that threatens to destabilize U.S. relations with China."

To date, extensive discussions between Chinese officials and top U.S. leaders — including President Obama and Defense Secretary Leon Panetta — have had little impact on what government and cybersecurity experts say is escalating and technologically evolving espionage. The Chinese deny such espionage efforts.

Internet search leader Google focused attention on the China threat three years ago by alleging that it had traced a series of hacking attacks to that country. The company said the breaches, which became known as "Operation Aurora," appeared aimed at heisting some of its business secrets, as well as spying on Chinese human rights activists who relied on Google's Gmail service. As many as 20 other U.S. companies were also said to be targeted.

A four-month long cyberattack against The New York Times is the latest in a long string of breaches said to be by China-based hackers into corporate and government computer systems across the United States. The Times attacks, routed through computers at U.S. universities, targeted staff members' email accounts, the Times said, and were likely in retribution for the newspaper's investigation into the wealth amassed by the family of a top Chinese leader.

The Wall Street Journal on Thursday said that its computer systems, too, had been breached by China-based hackers in an effort to monitor the newspaper's coverage of China issues.

Media organizations with bureaus in China have believed for years that their computers, phones and conversations were likely monitored on a fairly regular basis by the Chinese. The Gmail account of an Associated Press staffer was broken into in China in 2010.

Richard Bejtlich, the chief security officer at Mandiant, the firm hired by the Times to investigate the cyberattack, said the breach is consistent with what he routinely sees China-based hacking groups do. But, he said it had a personal aspect to it that became apparent: The hackers got into 53 computers but largely looked at the emails of the reporters working on a particular story. The newspaper's investigation delved into how the relatives and family of Premier Wen Jiabao built a fortune worth over $2 billion.

"We're starting to see more cases where there is a personal element," Bejtlich said, adding that it gives companies another factor to consider. "It may not just be the institution, but, is there some aspect of your company that would cause someone on the other side to take personal interest in you?"

In an interview with CBSNews.com, Mandiant principal consultant Nick Bennett said the firm has been investigating these kinds of incidents for years.

"In a broader picture, we've seen these attacks against lots of companies," said Bennett. "The Times is just unique in the fact that they've reported it, but we deal with, you know, dozens or hundreds of other companies that face these sort of issues, and the attackers are stealing intellectual property and information about journalists and Chinese dissidents and things of that nature from U.S. companies and companies around the world."

Journalists are popular targets, particularly in efforts to determine what information reporters have and who may be talking to them.

The Chinese foreign and defense ministries called the Times' allegations baseless, and the Defense Ministry denied any involvement by the military.

"Chinese law forbids hacking and any other actions that damage Internet security," the Defense Ministry said. "The Chinese military has never supported any hacking activities. Cyberattacks are characterized by being cross-national and anonymous. To accuse the Chinese military of launching cyberattacks without firm evidence is not professional and also groundless."

In a report in November 2011, U.S. intelligence officials for the first time publicly accused China and Russia of systematically stealing American high-tech data for economic gain. And over the past several years, cybersecurity has been one of the key issues raised with allies as part of a broader U.S. effort to strengthen America's defenses and encourage an international policy on accepted practices in cyberspace.

U.S. cybersecurity worries are not about China alone. Administration officials and cybersecurity experts also routinely point to widespread cyberthreats from Iran and Russia, as well as hacker networks across Eastern Europe and South America.

The U.S. itself has been named in one of the most prominent cyberattacks — Stuxnet — the computer worm that infiltrated an Iranian nuclear facility, shutting down thousands of centrifuges there in 2010. Reports suggest that Stuxnet was a secret U.S.-Israeli program aimed at destabilizing Iran's atomic energy program, which many Western countries believe is a cover for the development of nuclear weapons.

The White House declined comment on whether it will pursue aggressive action on China.

"The United States has substantial and growing concerns about the threats to U.S. economic and national security posed by cyber intrusions, including the theft of commercial information," said spokesman Caitlin Hayden. "We have repeatedly raised our concerns with senior Chinese officials, including in the military, and we will continue to do so."
