After Joshua Kaufman’s Macbook was stolen from his apartment in Oakland, he notified the police. Due to budget cutbacks, Oakland PD don’t respond to many non-violent crimes anymore like burglary, grand theft, and car wrecks, so initially they couldn’t help him. Then Josh activated a tracking program on it called Hidden. Like other similar programs, it gave him real-time remote access to his computer, letting him take pictures using its webcam and capture screenshots. He set up a Tumblr to post them, his story went viral, he gave the tracking info to the police, and they ended up trapping the thief and getting the laptop back to Josh.
