What is Zero-Day Exploit in cyber security?

A vulnerability in software that is exploited before the developer has a chance to fix it.

A zero-day exploit refers to a software vulnerability that is unknown to the software developer and is exploited by attackers before a patch or fix is available. These exploits are highly valuable to cybercriminals and can cause significant damage because there is no immediate defense against them. Organizations can mitigate the risk by using robust security practices, keeping software up to date, and employing advanced threat detection systems to identify and respond to zero-day attacks swiftly.
