The hacking of personal information on international students from a Kansas University computer database is "a matter of grave concern," Chancellor Robert Hemenway said Thursday.
KU's top administrator also said that a temporary "hole" that allowed a hacker to access and download information on 1,450 international students has been closed.
And Hemenway said KU is working closely with the FBI to find the person or persons responsible for the crime.
"This university highly values its international student community, and all our students," Hemenway said in a prepared statement.
"We are doing everything possible to contact those affected by this incident. We regret that this theft of data took place and are distributing information and resources our students can use to reduce their personal risk of identity theft."
Hemenway's statement was released in conjunction with a press conference held Thursday afternoon at KU, as the FBI began its investigation of the data theft, which was discovered about noon Wednesday.
The files, which were stored on a computer in KU's Academic Computer Center, were test files for the Student and Exchange Visitor Information System, which will allow universities to transmit information on international students to the Immigration and Naturalization Service, beginning in August.
The files included student information, such as Social Security numbers, passport numbers, cities and countries of origin, KU identification numbers and programs in school.
