What is a Zero-Day Vulnerability?

A zero-day vulnerability is a vulnerability in a software security flaw known to the software vendor but hasn’t been patched yet. This makes it potentially susceptible to cybercriminals or hackers.


Hackers can write code to target these vulnerabilities. They package it into malware called a zero-day exploit which then uses the vulnerability to compromise security or cause unwanted behavior.
