A Zero-Day Exploit is a cyberattack that targets a previously unknown software vulnerability for which no patch or fix currently exists. Attackers discover and leverage these flaws before the software vendor is aware of them, granting them a significant advantage. The “zero-day” designation signifies that the developers have had zero days to prepare a defense against the exploit.
