Three Purdue engineering students are facing charges after allegedly hacking into a professor's computer to change their grades.

The Journal & Courier in Lafayette reports Sujay Sharma and Mitsutoshi Shirasaki, both 24 of Lafayette, and 24-year-old Roy C. Sun of Andover, Massachusetts were charged Thursday. Sharma and Sun were arrested, but Shirasaki is in his native Japan, prosecutors say.

The newspaper reports an engineering professor reported that his password had been changed by an unknown party last November. The password was changed again in December and police were contacted a month later, when it was discovered that grades had been changed.

Sun, who graduated in May 2010 with a bachelor's degree in electrical engineering, reportedly had his grades changed between December 2008 and May 2010. The Journal & Courier, citing an affidavit of probable cause, reports Sun had D, F and "incomplete" grades changed to straight As.

Shirasaki had grades changed from Cs, Ds and Fs to As and Bs, and two As changed to A+ grades. Those changes occurred between May 2010 and December 2012.

Sharma had a D changed to an A and allegedly used one professor's computer to gain access to three tests.

According to the probable cause, the students used keyloggers on computers used by several professors to learn their passwords.

The newspaper could not confirm if Shirasaki and Sharma had graduated from the university.

The men face charges including conspiracy to commit computer tampering, conspiracy to commit burglary and conspiracy to commit computer trespass.
