(NBC) - A group of Haddonfield Memorial High School students have been turned over to police after allegedly hacking into the school's computer system.
The students used keystroke-logging software to obtain logins and passwords of about 200 school computers. School officials say the computers hold information such as grades, attendance, class schedules and statuses of homework assignments.
"It was confirmed late yesterday afternoon that several HMHS students developed a plan to capture secure passwords from staff/students who used a computer in the high school," Principal Michael Wilson said in a letter.
"We are confident this is a contained situation," said Wilson.
Wilson recommended that all students, parents and staff change their passwords for the internal system, as well as any passwords they might have used on the computers in the past six weeks.
The school district is not identifying the students and says the FBI might get involved in the investigation.
