Explanation:

Data theft can be defined as a cyber attack which typically involves an unauthorized access to a user's data with the sole intention to use for fraudulent purposes or illegal operations. There are several methods used by cyber criminals or hackers to obtain user data and these includes DDOS attack, SQL injection, man in the middle, phishing, sniffing, etc.

Sniffing can be defined as a form of cyber attack in which a malicious user gains access to a private network with the intent of finding out what information is stored on the network. Thus, it typically involves monitoring and capturing internet traffic or data packets transmitted through a private network in real-time using a sniffing tool, which may either be a software or hardware.
