18-year-old Mark Bao is a student and self-professed computer nerd at Bentley University in Waltham, Massachusetts. Two months ago, someone stole his computer. And last week, Mark realized he could have his revenge.
Mark remembered he'd set up his computer to back itself up online. And he could remotely access those backups. So he was actually able to log in and see what the thief had been doing with his computer.
