The error message “The Group Policy Client service failed to logon – Access is denied” suggests a problem with user permissions, which are managed by group policies in Windows environments. The unexpected modifications to system settings further indicate that an unauthorized user or process has gained higher-level permissions than originally assigned. This scenario is characteristic of an elevation of privileges breach, where an attacker gains elevated access to resources that are normally protected from an application or user. This can be achieved through various methods, including exploiting software vulnerabilities, configuration errors, or using social engineering techniques.
