One and a half months ago, somebody walked off with Mark Bao's MacBook Air, which had been left unattended in a Bentley University lounge. Normally, this episode would have been entirely unremarkable except for a victim understandably frustrated, angry - and out-of-pocket to the tune of $1,000-plus. But Bao wasn't your typical 18-year-old freshman. He knew his way around a keyboard - and then some.
He had taken the precaution of installing online backup software (called BackBlaze) on the computer and that now allowed him to gain entry into the purloined machine's browser history as well as to view its hard drive where he could track any updates. "It was still backing up files when I logged in on Sunday," he said in an email to CBSNews.com.
The person absconding with Bao's computer almost immediately used it take a self photograph....
That wasn't all.
"From the files on the computer and some legwork, I was able to track down who (the thief) was, his Facebook page, his email, and the (now) infamous videos," Bao noted.
