Zero-Day Exploit

Definition ∞ 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.
Context ∞ Zero-Day Exploits represent a significant threat in cybersecurity, and their discovery in platforms relevant to digital assets can lead to substantial financial losses. News reports often detail the emergence of such exploits affecting web browsers, wallet software, or blockchain infrastructure. The absence of immediate patches makes these attacks particularly potent, underscoring the importance of proactive security measures and rapid incident response.
