Answer:
Spear-phishing
Step-by-step explanation:
Spear-phishing is a coordinated attempt to obtain sensitive data from a single user, often for malicious reasons, such as account credentials or financial information.
This is obtained by collecting the victim's personal details such as their family, neighborhood, workplace, locations they visit, and what they recently purchased on the web.
The attackers then mask themselves to acquire sensitive information as a reliable friend or organization, usually via mail or other online communication.
It is the most effective form of using the internet to access confidential information, accounting for 91 percent of attacks.
