A zero-day attack, or 0day attack, occurs on the 0th day when a vulnerability is discovered an affects an application in such a way that the security industry has never seen before, attacking the application before it can be patched. Large-scale zero-day attacks are typically pre-distributed and set in motion before the attack actually takes place, granting maximum effectiveness between the initial attack and successful patch.
