A Zero-Day Attack refers to the exploitation of a publicly known but still unpatched vulnerability. This type of attack occurs when attackers take advantage of a security weakness for which a fix or patch has not yet been released by the vendor. The term “zero-day” refers to the fact that the developers have “zero days” to fix the issue because it has already been exploited in the wild. These attacks are particularly dangerous because they occur before the vulnerability is widely known, giving attackers the opportunity to exploit systems while they are still vulnerable.
References: The EC-Council’s Certified SOC Analyst (C|SA) program covers the concept of zero-day vulnerabilities and attacks as part of the training for security operations center analysts. Understanding these attacks is crucial for identifying and responding to incidents that involve unpatched software vulnerabilities. The information is consistent with industry standards and best practices for cybersecurity, as outlined in various EC-Council SOC Analyst study guides and courses1234.
