Question

attack occurs when malicious websites are set up to attack ers computers by transferring harmful software onto a users computer. black - hat hacking quarantining drive - by download dos i dont know yet

Explanation:

The question describes an attack where malicious websites transfer harmful software to users' computers. Drive-by download specifically refers to this scenario—unintended downloading of malware from a compromised or malicious website. Black-hat hacking is a broad term for unethical hacking, not the specific attack described. Quarantining is a defense method (isolating malware), not an attack. DoS (Denial of Service) attacks disrupt service, not transfer malware.

Answer:

C. drive-by download
