Cops: Students hacked school computers, changed schedules, grades

COMMACK, N.Y. -- Three students at a New York high school are facing criminal charges after police say they hacked into the school's computer system over the summer and changed grades and schedules, reports CBS New York.

Police say one of the boys, who are all 17, entered Commack High School on Long Island after hours, and installed a "keystroke logger" on computers. The device recorded the keystrokes of teachers who used the computers to log in to the computer system, and police say the boy was able to obtain their usernames and passwords when he retrieved the device several days later.

The schedules of 300 students at the school were affected in July, police told the station, and two of the students had their grades changed, reports the station. In one case, the alleged hacker changed a grade from a "94" to a "100."

The alleged hacker faces charges of burglary, computer tampering, identity theft, computer trespass and eavesdropping. The two others reportedly face computer tampering and criminal solicitation charges.

The school told the station all the altered schedules and grades were fixed, and that a full electronic security review is underway.
