A lengthy Bloomberg  article outlines a series of incidents that have alarmed security officials and some university leaders who fear that some countries are attempting to use American universities' foreign connections for the purpose of spying. The article notes numerous incidents, including an American researcher who was invited to give a talk abroad. Then someone there asked for a copy of her paper, inserted a thumb drive into her laptop, and downloaded every document she had. In another instance, Michigan State University was approached by a Dubai-based company about providing funds and students for the university's Dubai campus, which was struggling financially. Lou Anna K. Simon, president at Michigan State, contacted the Central Intelligence Agency because she was afraid the company might be a front for Iran. When the CIA couldn't confirm the company's legitimacy, Simon passed on the deal and shut down the Dubai campus.
The article also quoted from a 2011 Pentagon report that said that attempts by East Asian countries to obtain classified or proprietary information through "academic solicitation" (requesting to see academic papers or discuss work with professors), jumped eightfold in 2010.
