Spoofing is a broad term for the type of behavior that involves a cybercriminal masquerading as a trusted entity or device to get you to do something beneficial to the hacker — and detrimental to you. Any time an online scammer disguises their identity as something else, it's spoofing.

Sniffing collects data packets, analyzes network traffic, and sends those packets to the targeted traffic. Spoofing is the theft of the user's data. After that, it distributes malware, and phishing attacks make all sorts of data theft thanks to this data.
