A school board near London, Ont. will upgrade computer security after a hacker exposed passwords of up to 27,000 high school students.
The security breach Thursday left passwords for the student portals on a Facebook page that let people see student marks and schedules.
Officials with the Thames Valley District School Board say the upgrades should be done in a couple of weeks.
Passwords and web pages for students will then be encrypted.
London police are investigating the breach.
