A University of the Cumberlands student is accused of hacking into other students' accounts and using the information to blackmail them.

Sungkook Kim, 23, is charged with identity theft and unlawful access to a computer, according to a press release from the Kentucky Attorney General's office. The office's cybercrime unit conducted a joint investigation with Williamsburg police.

The investigation began after a female student received an anonymous message about personal information that had been stolen from her e-mail account. The e-mail threatened to expose that information unless she complied with some specific demands.

Investigators said Kim pirated another person's wireless router to send the threatening e-mails and that he had installed spyware on college library computers to capture logon IDs and passwords for students and faculty, according to the attorney general's statement.

Additional charges could be filed.

Kim is being held on a $100,000 bond.
