Which of the following is a common social engineering technique? Spear phishing Spoofing Denial of Service (DoS) attacks Malware attacks

Spear phishing and spoofing are common social engineering techniques.

1. Spear Phishing: This is a targeted form of phishing where fraudulent emails are sent to specific individuals or companies. They may appear to be from a trusted source and usually aim to steal sensitive data like credit card information and login credentials.

2. Spoofing: This is a technique where an attacker disguises themselves as a trusted source to gain access to important data. It can be done through emails, websites, IP addresses, and more.

Denial of Service (DoS) attacks and Malware attacks, while they are common cyber threats, they are not typically classified as social engineering techniques. Social engineering techniques usually involve manipulation or deception to trick users into making security mistakes or giving away sensitive information.
