  • Scarcity: Creating a sense of urgency or limited availability.
    • "[27:11] A: ... toilet paper's made in Canada and the U.S. it's not coming off the docks."
  • Authority: Impersonating authoritative figures to gain trust.
    • "[30:01] A: ... bully people into obeying authority unquestioningly."
  • Consistency: Leveraging individuals' desire to remain consistent with prior actions.
    • "[30:08] B: ... starting small to build up trust for bigger requests."
  • Liking: Building rapport to make the victim more susceptible.
    • "[31:09] A: ... familiarity and shared interests."
  • Social Proof: Using testimonials or references to validate the attack.
    • "[31:14] B: ... crypto scams leveraging social proof."

Research and Hypotheses

• Phish Failure Survey:

  • Exploring three primary reasons why individuals fall for phishing:
    1. Accidental: Distractions or lack of intent leading to impulsive clicks.
