A zero-day vulnerability is a computer security vulnerability unknown to the software developer or vendor. It is called a "zero-day" because it is discovered on the same day an attacker exploits it. This means that the vulnerability had existed for “zero days”, meaning that it was not found before it was controlled. Because the exposure is unknown, the software developer or vendor had not had the opportunity to fix it before it was used. Zero-day vulnerabilities can be very dangerous because malicious people can use them to access systems and data without being detected. Understanding the importance of keeping your computer and other devices up to date is essential. Software developers and vendors usually release updates to fix vulnerabilities, so downloading and installing them is necessary to ensure your device is safe. What impacts could it have?Zero-day vulnerabilities can be exploited in various ways.
What are some examples?
Zero-day vulnerabilities are typically discovered by security researchers who are on the lookout for them. Once discovered, the researcher can alert the affected party so that they can patch the vulnerability and protect their systems. In some cases, security researchers may also sell the details of the zero-day vulnerability to third parties, such as governments or cyber criminals. https://bit.ly/3vD97fv https://images.unsplash.com/photo-1660644808219-1f103401bc85?crop=entropy&cs=tinysrgb&fit=max&fm=jpg&ixid=MnwxMTc3M3wwfDF8c2VhcmNofDF8fHZ1bG5lcmFiaWxpdHklMjBzZWN1cml0eXxlbnwwfHx8fDE2NzIxNjczNjU&ixlib=rb-4.0.3&q=80&w=2000 https://deepakguptaplus.wordpress.com/2022/12/28/what-is-zero-day-vulnerability/
