Which one of the following is the odd one out?

Social engineering  

Virus  

Spoofing 

Phishing

Virus

The odd one out among the given options is "Virus."

To identify the odd one out from the given options, we need to understand what each term represents. Here's an explanation of each term:

1. Social engineering: This refers to the manipulation of individuals through psychological tactics to gain unauthorized access to systems or sensitive information.
2. Virus: In the context of computer systems, a virus refers to a type of malicious software that can replicate itself and infect other files or systems.
3. Spoofing: Spoofing is a technique used to deceive systems or users by falsifying information, such as the source of communication or the identity of a device.
4. Phishing: Phishing is an attempt to trick individuals into sharing sensitive information, such as usernames, passwords, or financial details, by impersonating a trustworthy entity.
5. Smishing: Smishing is a type of phishing that specifically occurs through text messages (SMS) or other SMS-based communication platforms.

Upon analyzing the options, we can see that all of them, except "Virus," are related to social engineering attacks and different methods of manipulating or deceiving individuals. Therefore, the odd one out is "Virus" since it refers to a type of malware rather than a social engineering tactic.

So, the answer is "Virus."
