A zero-day attack is when a malicious actor uses a zero-day exploit to plant malware, steal data or otherwise cause damage to users, organizations or systems. A similar but separate concept, zero-day malware, is a virus or malware for which the signature is unknown or as yet unavailable, and therefore undetectable by many antivirus software solutions or other signature-based threat detection ...
Zero-day vulnerability. A zero-day (also known as a 0-day) is a vulnerability in software or hardware that is typically unknown to the vendor and for which no patch or other fix is available. The vendor has zero days to prepare a patch as the vulnerability has already been described or exploited. Despite developers' goal of delivering a product ...
A zero-day vulnerability is a software vulnerability discovered by attackers before the vendor has become aware of it. Because the vendors are unaware, no patch exists for zero-day vulnerabilities, making attacks likely to succeed. A zero-day exploit is the method hackers use to attack systems with a previously unidentified vulnerability.
A zero day attack can happen to any company at any time, often without them realizing. High-profile examples of zero day attacks include: Sony Pictures: Potentially the most famous zero day attack took down the Sony network and led to the release of its sensitive data on file-sharing sites. The attack, in late 2014, saw the leak of information ...

A zero-day attack is one that is discovered while it is already in progress, meaning a security team has “zero days” to prepare or remediate the vector through which the attacker gained entry. Indeed, according to the National Institutes of Standards and Technology (NIST), a zero-day attack “exploits a previously unknown hardware ...
