This detection rule identifies potentially malicious activity involving the Windows Update Agent (wuauclt.exe) when it is executed without any command line flags. Normally, the Windows Update Agent is used to manage updates on Windows systems and operates with specific command line parameters. A lack of command line flags can indicate that the process is being executed in an atypical manner, often associated with evasion tactics used by malware, such as ransomware. This rule employs a combination of process creation and command line analysis to trigger alerts when the wuauclt.exe process is executed without expected command line arguments, thus raising the alert level to high given the potential severity of such incidents. The rule references dnstructions to analyze such executables and highlights previous incidents associated with similar patterns of execution. It is recommended for use in environments where Windows updates are closely monitored, and security teams should investigate any alerts generated to determine the legitimacy of the process execution.
