Question

1. which tactic is commonly used in spear-phishing attacks? *

sending mass emails with generic greetings.
including specific details about the recipient, such as their name or position.
attaching a file with a random name like file123.txt.
using vague language without any context.

Explanation:

Spear - phishing is a targeted form of phishing. In spear - phishing, attackers gather specific information about the target (like name, position, etc.) to make the attack seem more legitimate and personalized. Sending mass emails with generic greetings is more like regular phishing. Attaching a file with a random name and using vague language without context are not typical spear - phishing tactics as spear - phishing relies on personalization. So the tactic commonly used in spear - phishing is including specific details about the recipient.

Answer:

B. Including specific details about the recipient, such as their name or position.
