The principle of urgency in social engineering attacks relies on creating a sense of immediate importance or time sensitivity to manipulate the target's behavior. Attackers employing this principle introduce urgency through various means, such as emphasizing deadlines, imminent consequences, or time-limited opportunities. By exploiting the fear of missing out or the desire to avoid negative outcomes, the attacker aims to override the target's rational thinking and prompt them to take immediate action. This can lead the victim to disclose sensitive information, perform tasks without proper verification, or bypass security measures in haste.
