Renamed Whoami Execution
This rule detects the execution of the 'whoami.exe' utility when its executable file name has been changed from the original 'whoami.exe'. Adversaries often rename legitimate system utilities to evade detection by security tools that monitor for specific process names. This technique is commonly used during the discovery phase to gather information about the compromised system's user context without triggering alerts associated with the standard 'whoami.exe' process name.
