Which of the following is an example of spoofing?

Spoofing involves deceiving systems or individuals by impersonating another identity, often to mislead or gain unauthorized access to information or resources. Disguising an IP address is a common example of this practice. When an attacker substitutes their real IP address with a fake one, they can mask their identity and often bypass security measures, creating opportunities for cyberattacks or illicit activities without being easily traced.

This method is frequent in various attacks, including denial-of-service attacks, where the attacker may want to hide their true origin to avoid detection. By obscuring their IP address, they can manipulate traffic or access sensitive data while pretending to be a trusted source. Thus, disguising an IP address exemplifies the fundamental concept of spoofing by altering the perceived identity of the sender or user in a digital communication.
