Q & A
What method did the scammer use to accurately predict the stock prices?
-The scammer used a method of dividing and conquering his victims through a mathematical game. He would call a large group of people, tell half that a stock would go up and the other half that it would go down. He would then repeat this process over several weeks, narrowing down to a small group of people to whom he appeared to always predict correctly.
How did the scammer try to exploit Jack after gaining his trust?
-The scammer tried to exploit Jack by telling him about a company whose stock price was going to explode and that they were in the initial investor round. He asked Jack if he wanted to invest, starting with a question about investing ten grand.
What was Rachel's origin story that led her to social engineering?
-Rachel's origin story began with her watching the movie Harriet the Spy, which made her realize that being a spy was a job girls could do. This idea stayed with her through her childhood and later, despite not getting into coding, she found her way into social engineering through a nonlinear path involving neuroscience, behavioral psychology, and improv.
How did Rachel get into the field of information security?
-Rachel got into information security after her husband introduced her to Defcon, an annual hacker conference. Despite her initial reluctance, she attended and was fascinated by the social engineering contest. This experience sparked her interest and led her to apply for the contest, which she eventually won, launching her career in social engineering.
What is the Social Engineering Village that Rachel's husband described to her?
-The Social Engineering Village is a popular area at the Defcon conference where participants demonstrate various social engineering techniques. Contestants are placed in a soundproof glass booth in front of an audience and make calls to companies to extract information, showcasing their skills in elicitation, pretexting, and persuasion.
What was the strategy Rachel used to trick the bank's customer support into giving her access to accounts?
-Rachel used a strategy of posing as a customer who lost access to all her devices and was traveling abroad. She attempted to convince the support team to change the email address or phone number associated with the account to one she controlled. When this failed, she switched to a phone call approach, spoofed the customer's phone number, and used voice manipulation and a convincing story to gain the support team's trust.
How did Rachel manage to spoof phone numbers?
-Rachel managed to spoof phone numbers by using an app available on the App Store, which allowed her to make calls appear as though they were coming from a different number, in this case, the customer's number that she was trying to mimic.
What was the result of Rachel's attempt to gain access to the bank accounts?
-Rachel was successful in her attempts to gain access to the bank accounts. She managed to convince the support team to send her documents for identity verification. Using Photoshop, she and her husband created fake documents that matched the account details, which granted her full admin access to the accounts.
What was the purpose of the edge cases that Rachel helped the company set up after the penetration test?
-The purpose of the edge cases was to create scenarios that would help the company identify and prevent potential security breaches in the future. These scenarios would test the company's protocols and help them find practical ways to verify identity correctly and make it harder for attackers to gain access.
What is the significance of LinkedIn in the context of social engineering?
-LinkedIn is significant in social engineering because it provides a wealth of personal and professional information about individuals. This information can be used to target specific people within a company, guess their email addresses, and even deduce technical details about the company's infrastructure, making it easier for social engineers to carry out their attacks.
