A zero-day (also known as a 0-day) is a vulnerability or security hole in a computer system unknown to its owners, developers or anyone capable of mitigating it. Until the vulnerability is remedied, threat actors can exploit it in a zero-day exploit, or zero-day attack.
A zero-day exploit is a cyberattack vector that takes advantage of an unknown or unaddressed security flaw in computer software, hardware or firmware. "Zero day" refers to the fact that the software or device vendor has zero days to fix the flaw because malicious actors can already use it to access vulnerable systems.
A zero-day exploit (also called a zero-day threat) is an attack that takes advantage of a security vulnerability that does not have a fix in place. It is referred to as a "zero-day" threat because once the flaw is eventually discovered, the developer or organization has "zero days" to then come up with a solution. What is a vulnerability?
A zero-day attack is the use of a zero-day exploit to cause damage to or steal data from a system affected by a vulnerability. What are zero-day attacks and how do zero-day attacks work? Software often has security vulnerabilities that hackers can exploit to cause havoc.
