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.
Zero-day vulnerabilities are often classified as alive—meaning that there is no public knowledge of the vulnerability—and dead—the vulnerability has been disclosed, but not patched. If the software's maintainers are actively searching for vulnerabilities, it is a living vulnerability; such vulnerabilities in unmaintained software are called immortal.
Zero-day vulnerability. As mentioned above, a zero-day vulnerability refers to a previously unknown security gap that hasn't been publicly disclosed or patched by the vendor. The term zero-day indicates that the vendor has had zero days to address the issue. Cybercriminals can exploit these vulnerabilities to compromise systems, steal data, or ...
A zero day (or 0-day) vulnerability is a security risk in a piece of software that is not publicly known about and the vendor is not aware of. A zero- ay exploit is the method an attacker uses to access the vulnerable system.
- A zero-day attack is so-called because it occurs before the target is aware that the vulnerability exists.
- Yes, if companies remain vigilant against the threat of zero-day attacks, businesses must have a strategy in place.
- A zero-day attack can happen to any company at any time, often without them realizing. High-profile examples of zero-day attacks include:Sony Pictu...
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 zero day exploit?
A zero-day vulnerability is a software vulnerability discovered by attackers before the vendor has become aware of it. Because the vendors are unaware, no patch exists for zero-day vulnerabilities, making attacks likely to succeed. A zero-day exploit is the method hackers use to attack systems with a previously unidentified vulnerability.
