During a pretexting event, how is a target typically contacted?
-
By e-mail
-
By phone
-
In person
-
Through another person
Correct Answer
A. By phoneExplanation
During a pretexting event, a target is typically contacted by phone. This method allows the attacker to establish a more personal and convincing interaction, as they can use voice manipulation techniques and social engineering tactics to gain the target's trust and obtain sensitive information. Email or other forms of communication may lack the same level of immediacy and personal touch that a phone call provides, making it a less effective choice for pretexting.Rate this question:
