A Zero-day vulnerability refers to a security flaw in software or hardware that is unknown to the vendor or has not yet been patched.

These attacks are highly dangerous because they take advantage of the absence of defenses due to the lack of awareness or mitigation options.

A. Spoofing is a form of impersonation, not necessarily tied to unpatched vulnerabilities.

B. Brute-force attacks rely on repeatedly guessing credentials and are not related to software flaws.

C. DoS (Denial of Service) attacks are meant to overwhelm systems and don't necessarily exploit unknown vulnerabilities.

All-in-One Exam Guide adds:

“End-of-life notifications serve as a final warning that continued use of the OS will be insecure and unsupported. It’s crucial for administrators to plan migration”.
