In its court filing, Harvard listed some of its most notable alumni who enrolled as foreign students. The list includes Benazir Bhutto, the former prime minister of Pakistan; Ellen Johnson Sirleaf, the former president of Liberia; Empress Masako of Japan; and many leaders of major corporations.Many of the world’s top students spend years preparing for their college applications, sometimes working with admissions consultants such as Crimson Education, a company named after Harvard’s school color. Crimson clients recently admitted to Harvard were shocked by the government’s action, said Jamie Beaton, a Harvard alumnus from New Zealand who founded the company. But rather than looking for other options, many students quickly shifted to finding a way forward with Harvard, he said.

Still, some current students and those bound for the university in the fall were weighing other opportunities. Two universities in Hong Kong on Friday extended invites to affected students.“It feels like my world has exploded,” said Fang, a Chinese student who was accepted to Harvard for a master’s program. She also spoke on the condition that only her first name be used out of fear that she could be targeted.Her student visa was approved just this week. “If America becomes a country that doesn’t welcome me, I don’t want to go there.”

The recent developments forced Aleksandra Conevska, a Canadian graduate student researching climate change, to cancel her summer research and briefly look for jobs in Canada. But her thinking has since shifted, and she says she plans to remain at Harvard.“I’ve already invested in this country, and I’m not going to give in,” she said.

The U.S. government’s action against Harvard has dominated news in countries around the world, said Mike Henniger, president and CEO of Illume Student Advisory Services, which helps colleges in the U.S., Canada and Europe recruit international students. He is traveling in Japan and awoke to the news Friday with dozens of emails from colleagues.

The reactions from the international community, he said, were incredulous: “‘Unbelievable!’ ‘Oh My God!’ ‘Unreal!’”for its past campaigns targeting the U.S. and its allies.

The hackers used a variety of tactics to gain access, including, which involves sending authentic-looking messages to a potential victim that contain links to harmful software or requests for sensitive information.

The Russian team also exploited security vulnerabilities in computer devices used at small and in-home offices, networks that often lack the security measures found in larger systems.The hackers didn’t use particularly innovative techniques, according to Grant Geyer, chief strategy officer at the cybersecurity company Claroty. Nevertheless, the sprawling yet carefully orchestrated effort gives the Russians a “granular understanding” of the aid sent to Ukraine, he said.
