Silicon Valley Quote
Gilfoyle: Monica... gaining someone's confidence is easy. Appear open and interested by mimicking their body language and repeating what they say back to them.
Monica: So, you just repeat what they say?
Gilfoyle: I just repeat what they say. I was social engineering them. Once trust is established, the social engineer simply offers up information, and the subject will reciprocate: Pets names, kids names, birthdays. Then, that information is entered into a word list generator. Pop it with their hash into John The Ripper, and within minutes, you have their passwords.
