A zero-day refers to a flaw in software, hardware, or firmware that is unknown to the vendor or responsible party—and therefore has “zero days” of warning before being exploited.
The term can describe the vulnerability itself or the attack that occurs before a fix is available.
Once publicly disclosed, a zero-day becomes known as a 0-day or one-day vulnerability.
Cybercriminals exploit these weaknesses to infiltrate corporate networks, either launching immediate attacks or remaining undetected until the most damaging moment.
