Def. A Zero-day threat (also known as 0-day) is a computer-software threat that is unknown to, or unaddressed by, those who should be interested in mitigating it. The term is derived from the age of the exploit, which takes place before or on the first (“zeroth”) day of awareness of the exploit or threat.
An exploit directed at a zero-day is called a zero-day exploit, or zero-day attack.
