Usurpation, also known as hijacking, occurs when attackers gain unauthorized access and control over a computer system. This can involve replacing legitimate programs with their own malicious ones, giving them complete control over the system. Encryption refers to the process of encoding data to prevent unauthorized access, sniffing refers to intercepting data on a network, and spoofing refers to masquerading as a trusted entity to trick users. None of these options specifically refer to the scenario in the question.
