When a user says “GoogolPlex, turn off the lights,” Siri hears this as “Google ‘Plex turn off the lights,’” interpreting that the user wants to Google something. Siri then searches Google for the words “Plex turn off the lights,” and this is where GoogolPlex comes in. We are able to get the words the user was asking Siri by intercepting the request between Siri and Google with a man-in-the-middle exploit.
