How would the attacker know that you mashed the keyboard when answering 'What high school did you go to?' ?

Most likely from a "helpful" CS agent offering up the hint above. "It's really weird" or "I've never seen that one before" or just an odd chuckle. Anything an attacker could use to gain an advantage will be used to compromise you eventually.
