A Zero-Day Exploit is a type of cyberattack that occurs when hackers exploit a software vulnerability that is unknown to the software vendor or developers. Because the vulnerability is undisclosed, there is no patch or fix available at the time of the attack, leaving systems exposed to potential harm. The term “zero-day” refers to the fact that developers have “zero days” to address the vulnerability before it is exploited. These exploits are highly dangerous and often used in targeted attacks or cyber espionage.
