Zero-day Attack

Zero-day Attack

A zero-day (or zero-hour or day zero) attack or threat is an attack that exploits a previously unknown vulnerability in a computer application, meaning that the attack occurs on "day zero" of awareness of the vulnerability. This means that the developers have had zero days to address and patch the vulnerability. Zero-day exploits (actual software that uses a security hole to carry out an attack) are used or shared by attackers before the developer of the target software knows about the vulnerability.

Famous quotes containing the word attack:

    “The small perplexities of small minds eddy and boil about you. Confident from the experience that has led you out of these same dangers, you attack each problem as it appears, unafraid.”
    —Alice Foote MacDougall (1867–1945)
