What is a Zero Day Exploit?

Zero-Day Exploit

A zero-day exploit is a cyber attack that takes advantage of a previously unknown software vulnerability, typically one for which no patch or fix is yet available.

"Zero-day" refers to the fact that developers and security teams have zero days to fix the flaw before it is exploited. Attackers can use zero-day exploits to bypass defenses and compromise systems before the vulnerability is discovered and addressed.

Zero-day exploits are highly valuable to attackers because they offer a window of opportunity to execute undetectable attacks. These exploits are often sold on the black market or used in targeted attacks to steal sensitive data, deploy ransomware, or disrupt operations.

Organisations can mitigate the risk of zero-day exploits by using advanced threat detection tools, implementing a strong patch management process, and employing defense-in-depth strategies to reduce the impact of undiscovered vulnerabilities.
