Check Elevated CMD using whoami — Detection Rule
The following analytic identifies the execution of the "whoami" command with the "/group" flag, where the results are passed to the "find" command in order to look for a the string "12288". This string represents the SID of the group "Mandatory Label\High Mandatory Level" effectively checking if the current process is running as a "High" integrity process or with Administrator privileges. It leverages data from Endpoint Detection and Response (EDR) agents, focusing on process and command-line telemetry. This activity is significant because it is commonly used by attackers, such as FIN7, to perform reconnaissance on a compromised host. If confirmed malicious, this behavior could indicate an attacker is assessing their privilege level, potentially leading to further privilege escalation or persistence within the environment.
