This rule detects the execution of the built-in Windows command 'rmdir', which is used to remove directories. Adversaries often utilize this command to eliminate residual files or directories that may provide insights into their activities, thus minimizing their footprint after an intrusion. The rule specifically looks for the invocation of 'rmdir' with flags that signify recursive deletion and quiet mode, indicating that the command is being executed to delete directory contents without prompting for confirmation. This activity could be indicative of an adversary trying to erase signs of their presence on a compromised system or during a cleanup phase to remove evidence of their activities. By monitoring this command, security teams can detect potential malicious behaviors linked to post-exploitation tactics.
