What is the term used when attackers create false identities to manipulate network traffic?

The correct term for when attackers create false identities to manipulate network traffic is spoofing. Spoofing involves impersonating another person or device on a network in order to deceive or manipulate. This can take various forms, such as IP spoofing, where a malicious actor sends IP packets from a false (or "spoofed") source address, making it appear as though the communication is coming from a legitimate entity.

Spoofing is commonly employed in various attacks, such as man-in-the-middle attacks or denial-of-service attacks, where the objective is to disrupt legitimate communication or gain unauthorized access to sensitive data. The process often exploits the trust that users and systems place in certain IP addresses or domain names, leading to potential security breaches.

Other terms, while related to cybersecurity, do not specifically describe the act of creating false identities in the context of network manipulation. Phishing involves tricking individuals into providing personal information, often through deceptive emails, but it doesn't directly pertain to manipulating network traffic with false identities. Faking and emulation, while they may convey a sense of imitating, do not specifically relate to identity deception in networking contexts.
