Unfriended (2014)

While video chatting one night, six high school friends receive a Skype message from a classmate who killed herself exactly one year ago. A first they think it's a prank, but when the girl starts revealing the friends' darkest secrets, they realize they are dealing with something out of this world, something that wants them dead. Told entirely from a young girl's computer desktop, Unfriended redefines 'found footage' for a new generation of teens.
