Summary
This detection rule identifies potential threats associated with the theft or forgery of authentication certificates within Windows environments. It triggers an alert when five or more analytics from the Windows Certificate Services story activate within a designated timeframe. The detection leverages aggregated risk scores and event counts sourced from the Risk data model, indicating potentially malicious activity that could compromise authentication mechanisms. Attackers exploiting such vulnerabilities could gain unauthorized access to sensitive systems and data, leading to significant security breaches. This rule aims to strengthen threat detection capabilities by monitoring unusual activity related to certificate services in order to mitigate the risks associated with improper authentication practices.
