What is a Zero-Day Exploit? What Can be Done About Them?
In cybersecurity, a zero-day exploit refers to the method a hacker uses to take advantage of a security vulnerability in a computer system, software, or network.

The term “zero-day” indicates that the security vulnerability is being exploited or targeted as soon as discovered, giving IT and security teams zero days to prepare or patch the vulnerability.
Cybercriminals constantly target vulnerabilities in Microsoft Exchange; therefore, zero-day exploits will continue as new attack methods are always on the horizon. What can be done to proactively detect zero-day exploits before they become known? It comes down to detecting unusual or suspicious activity that would tip off an analyst to an attack.
Why It Is Important to Monitor Zero Day Exploits?
Cybercriminals commonly attempt to compromise enterprises before zero-day patches are implemented and advanced attackers will exploit zero-day vulnerabilities before they are even known. For example, in September of 2022, Microsoft announced “Reported Zero-Day Vulnerabilities in Microsoft Exchange Server” for CVE-2022-41040 and CVE-2022-41082...Read More!
