Via

Skype Conversation that was screen recorded on July 13th, 2012 captures a face of an "alien being" when one of the video cams is turned on and off on its own, interrupting the live feed from the camera. As of now, it is unclear whether the Skype communication was hacked by a hacker but Skype claims all conversations are encrypted. Was this simply a hoax or real alien encounter?
