America’s research universities, among the most open and robust centers of information exchange in the world, are increasingly coming under cyberattack, most of it thought to be from China, with millions of hacking attempts weekly. Campuses are being forced to tighten security, constrict their culture of openness and try to determine what has been stolen.
Tracy B. Mitrano, the director of information technology policy at Cornell University, said that detection was “probably our greatest area of concern, that the hackers’ ability to detect vulnerabilities and penetrate them without being detected has increased sharply.”
Like many of her counterparts, she said that while the largest number of attacks appeared to have originated in China, hackers have become adept at bouncing their work around the world. Officials do not know whether the hackers are private or governmental. A request for comment from the Chinese Embassy in Washington was not immediately answered.
Analysts can track where communications come from — a region, a service provider, sometimes even a user’s specific Internet address. But hackers often route their penetration attempts through multiple computers, even multiple countries, and the targeted organizations rarely go to the effort and expense — often fruitless — of trying to trace the origins. American government officials, security experts and university and corporate officials nonetheless say that China is clearly the leading source of efforts to steal information, but attributing individual attacks to specific people, groups or places is rare.
The increased threat of hacking has forced many universities to rethink the basic structure of their computer networks and their open style, though officials say they are resisting the temptation to create a fortress with high digital walls.
“A university environment is very different from a corporation or a government agency, because of the kind of openness and free flow of information you’re trying to promote,” said David J. Shaw, the chief information security officer at Purdue University. “The researchers want to collaborate with others, inside and outside the university, and to share their discoveries.”
Some universities no longer allow their professors to take laptops to certain countries, and that should be a standard practice, said James A. Lewis, a senior fellow at the Center for Strategic and International Studies, a policy group in Washington. “There are some countries, including China, where the minute you connect to a network, everything will be copied, or something will be planted on your computer in hopes that you’ll take that computer back home and connect to your home network, and then they’re in there,” he said. “Academics aren’t used to thinking that way.”
Bill Mellon of the University of Wisconsin said that when he set out to overhaul computer security recently, he was stunned by the sheer volume of hacking attempts.
“We get 90,000 to 100,000 attempts per day, from China alone, to penetrate our system,” said Mr. Mellon, the associate dean for research policy. “There are also a lot from Russia, and recently a lot from Vietnam, but it’s primarily China.”
Other universities report a similar number of attacks and say the figure is doubling every few years. What worries them most is the growing sophistication of the assault.
For corporations, cyberattacks have become a major concern, as they find evidence of persistent hacking by well-organized groups around the world — often suspected of being state-sponsored — that are looking to steal information that has commercial, political or national security value. The New York Times disclosed in January that hackers with possible links to the Chinese military had penetrated its computer systems, apparently looking for the sources of material embarrassing to China’s leaders.
This kind of industrial espionage has become a sticking point in United States-China relations, with the Obama administration complaining of organized cybertheft of trade secrets, and Chinese officials pointing to revelations of American spying.
