University officials concede that some of the hacking attempts have succeeded. But they have declined to reveal specifics, other than those involving the theft of personal data like Social Security numbers. They acknowledge that they often do not learn of break-ins until much later, if ever, and that even after discovering the breaches they may not be able to tell what was taken.
Universities and their professors are awarded thousands of patents each year, some with vast potential value, in fields as disparate as prescription drugs, computer chips, fuel cells, aircraft and medical devices.
“The attacks are increasing exponentially, and so is the sophistication, and I think it’s outpaced our ability to respond,” said Rodney J. Petersen, who heads the cybersecurity program at Educause, a nonprofit alliance of schools and technology companies. “So everyone’s investing a lot more resources in detecting this, so we learn of even more incidents we wouldn’t have known about before.”
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.
